Hi Mick, Quick tip you can try in just 5 minutes, to narrow it down, to possibly "tappets needed adjusting". Simply idle the car, then carefully unscrew the rocker cover oil filler cap, & listen at the oil filler hole with your ear. The tappets are only inches from your ear at this location, so if it is the tappets, then the "ticking" should be quite loud. Increase the revs slightly, and the ticking should increase in speed accordingly. Might be a good idea to put a tissue over your listening ear, with a light rubber band, so you don't get any oil spits in there. I'm hoping, for your sake, that it is the tappets, because that is a dead simple fix, you can do yourself on a lazy Sunday afternoon. Cheers Banjo

Hi Mick, No problem ! You didn't say were you are located, but I just found your earlier posts & the pictures you posted of your auntie's car. I gather you are in Victoria, if that's where your auntie lives. Disregard my previous comment about it maybe being modified by an earlier owner, as I would think, if auntie purchased it new, she probably hasn't added or changed anything, and it will be dead stock standard. Cheers Banjo

Hi Mick, Welcome aboard ! Ticking sounds in older engines are common place, and certainly more likely in a car that has been sitting for several years. However, if you have changed the oil several times & given it a few good hard runs, it should have freed itself by now, if it was something just sticking. The 4K-Cs to my knowledge only had solid lifters, unlike most 5K engines, that had hydraulic lifters, and these could have blocked up & are not pumping up, after sitting for years. The head would have to come off, if you were to try & take the lifters out. I would initially, just take the rocker cover off, which is not a hard job. If the tappets have adjustments on them, then the lifters are solid. If the tappets have no adjusters, then the lifters are hydraulic. (You just never know what the history of an older engine is, and what others before you, might have modified or changed on it) I would do a full tappet adjustment, and see if there are any wide settings. If the rocker faces are "grooved" where they contact the top of the valves, you may have to have them faced, or you can lap them yourself, on an oiled sharpening stone. Then run the car, & see what changes to the ticking, if any, are audible. If the ticking noise is evident, when the engine is idling, you can sometimes narrow down it's origin, using an automotive stethoscope. A cheap stethoscope can be made from a piece of hose with a rod clamped in one end, although not as sensitive as a professional one. Anyway, give those suggestions a try, and come back to us, in this thread, with what you found, and we'll see if we can help some more. Where are you located ? There maybe a Rollaclub member, close by, who is prepared to assist you. Cheers Banjo

Altezzaclub is probably right, that it would not be a good idea to use a thicker oil, because of your colder climate in Norway. Unfortunately, by the time it gets to the stage that you can smell the oil burning, it's probably time for the engine to come out, for a hone & new rings, or a rebore, if the bores are too "wavey". The smoke is usually the result of oil in the sump getting up into the combustion chambers, past the rings & pistons, although shot valve stem seals plus worn valve stems & guides will also produce a similar effect. Make sure the spring loaded valve on the top of the rocker cover is clean & working, because it reliefs pressure build up in the crankcase, which can also assist in driving oil up past worn rings. This usually happens because of carbon building up in the piston ring grooves, such that the rings can't move to effectively scrape the oil off the cylinder walls. There are some after market oil additives, that are claimed to seal smoking engines, but if they do work, it is usually only for a limited period. However, in some old motors, the build up between the rings, actually helps seal, & avoid more oil consumption. I once made the big mistake in an olde Corolla, of filling the tank with the best premium highest octane fuel available at the pump. By the time that tank had been consumed, the cleaning additives in the premium fuel, had loosened the carbon, and the engine was smoking like a steam train. Big mistake ! Cheers Banjo

Good Heavens that Glen Innes can be a cold hole ! This was my little KE30 at the Anna Bella motel at 7:00am last Friday. Fog right down to ground level, & they told me there was "black ice" down on the highway near Guyra. And a couple of days later, much warmer outside Grafton & at Lawrence on the mighty Clarence. Cheers Banjo

Hi Dave, Any bolt on upgrades you do to your 4K should be swappable to your 5K, if you manage to find one in NZ. Actually, a 4K-U with dished pistons, almost produces as much HP as a 5K, if you look up the specs. The Aisan carbies are getting pretty old now, but are very basic, and easy to work on. Repair kits are still available on ebay, and I see you can buy new Aisan replicas, cheaper than you can have an old one professionally rebuilt. Never met anyone though, who has purchased & tried one. The Aisan can easily be serviced, if you strip them, and completely clean them in a bath, to remove all the fuel lacquer build up in all the small internal passages. As a minimum, as Altezzaclub always advises, run a spray can of carby & throttle cleaner through every orifice. It helps to have the Toyota yellow bible manual with the carby circuit therein, but the following post on the link below, has some good advice & a better expanded circuit of the Aisan carby. http://members.toast...arbie_notes.htm There are very few adjustments visible on the Aisan carby, other than idle mixture, idle speed & the point where choke use, slightly increases idling speed. According to the "yellow bible" the pickup point of the secondary butterfly, can be adjusted by bending the little link, which slides in a curved slot behind the accelerator cable curved actuator arm. The slot could also be lengthened or shortened, to affect the point of secondary coming in, if necessary, if you feel that is contributing to your flat spot. The single biggest issue, is the worn shafts, and the leakage of air into the venturis, upsetting the A/F ratio. These carbies are getting very old & even the slightest leakage in this area has a great effect. This was brought home to me last week, on a trip down the New England highway from Brisbane to Sydney. The KE30 was running well, going up Cunninghams Gap in 4th gear. The engine was running sweetly, & well tuned, as the plugs colour was a near perfect light tan colour. 10 minutes north of Glen Innes, the engine started to "fluff", & I suspected a sticking needle & seat. Light was fading fast, so I decided to fix it in the morning. Morning saw a thick layer of ice over all the KE30, & my fingers were numb. I waited until 8:30am, when AutoOne opened their doors, & I grabbed a can of Carby & throttle cleaner, and took the top off the carby & cleaned needle & seat, & all jets, in the Woolworths carpark opposite. Reassembled, fired her up & off I went to Armidale, only to find she was still not going well, with top end restricted by about 10-15 klms/hr. I thought I'd drive to Armidale & then take another look. At a little town I had to stop at a pedestrian crossing & the engine cut out. Instantly I knew what the problem was. The idling shut off valve was not opening. I pulled over, and checked the connection, which I had unplugged to remove the top of the carby. The plug connection was intermittent & o/c. I plugged it in & out a few times, and away I went, with the engine as sweet as ever. It reminded me, that the main, secondary, & power jets, plus the idling circuit are not all independent, but work accummulatively. The idling circuit is still in play, even when driving & running, and does effect the A/F ratio, enough to make A/F ratio anything but perfect. Cheers Banjo

Hi Dave, Although today I'm running a 4KU in my KE30, I'm a real advocate of the 5K. I've had two and they are so much more responsive, with more power & torque, as long as you change or get rid of the 5K dizzy, whose advance curve is designed for commercial vehicles like the Hi Ace vans & Toyota forklifts. (good places to look for 5K in Ozz; not sure about NZ) I'll comment on the Aisan carby setup later today, as I am currently running my Corolla up the north coast of NSW from Sydney to Brisbane, after a run down the New England at the end of last week, to test a few mods I've done to the front suspension & brakes. Have put 2000+ klms on it in 4 days, a lot of which has been at 100klm/hr, where allowable. Had a little bit of carby trouble at Glen Innes in NSW, and stripped the carby & cleaned in Woolworth's car park. Thought I knew most things about this carby, but you can always learn more. I'll relate & answer your query later. Cheers Banjo

Absolutely love the videos ! But then I always knew I would, once you got it all sorted. That looks like so much fun. Just stick a good 5K in it ! That's the simplest way of getting some extra horses. Cheers Banjo

Hi Cameron, After working with the ARDROX 2526 at O/S 22 deg C, I shudder to think what the fumes would be like at 90 deg C. You'd want a full gas mask & helmet. You're right about it dissolving rubber. I bought some industrial long rubber gloves, that went up half way to my elbows. They were chemical resistant gloves, but felt like mostly rubber. After using the ARDROX 2526 for about 20 -30 mins, I could feel my hands getting wet & sweaty inside the gloves. I took them off, and the ARDROX was working it's way straight through the gloves. So anyone using the ARDROX, 2526, please do take precautions, but it does work well. Like Alteazzclub says, the nastier they are, the better they work. Next time I use it, to strip the boot lid, I will put a small tin of ARDROX 2526, in a tub of hot water, to heat it up a bit, & see if it even quicker to work it's magic. Cheers Banjo

Well finally got around to stripping the paint off my KE30 bonnet today, with the ARDROX 2526. 40 years of baked on paint. It worked extremely well. It helps to break the surface of the paint, with some 60 grit paper, to let the chemicals get into the paint, & do it's magic. However, you can just apply, & then scrape away one or 2 layers of paint at a time, and then apply again, until you get tho the bare metal. It's very toxic, and not to be treated likely. I used long chemical gloves, a mask, and a charcoal nose & mouth filter. Good stuff ! Certainly saves a lot of elbow grease. Cheers Banjo

Believe these are the studs ones you really need, which are available in the USA. https://sportcompactwarehouse.com/arp-am5-000-1lb-stud-m10-x-1-25?Year=1976&Make=Toyota&Model=Corolla& Cheers Banjo

What was the first model Corolla in Australia, that was supplied/fitted with an electronic speedo, with a pulse VSS fitted to the gearbox, rather than a cable drive ? Cheers Banjo

Hi Ian, Thanks ! Yes, I did notice the analogue trip & odometer dials on a couple of pictures I gleaned on the web. Must get down to the wreckers soon & have a hunt around. Cheers Banjo

I was working on a fellow Rollaclub members KE20 with a 4K engine fitted, a couple of weekends ago, chasing a few electrical gremlins, as the result of a dodgy electrician being let loose under the dash. It had been a long day, and we still had to refit the freshly cleaned & oiled distributor, as the timing light had indicated no auto advance, the bob weights having all frozen up. The day light was fading fast, and the engine had been turned over with the spark plugs out, when we measured the cylinder compression pressures. We still had to “time” the engine & find TDC. This is always a pain, and can involve at worst, removing the rocker cover, and watching the rockers on no 1 cylinder, or sticking your finger in number 1 spark plug hole, with the possibility of a trip to hospital, if your finger gets sucked in. I’d already put a bit of “whiteout” on the crankshaft pulley nick for lining up TDC, and not wanting to go through all that rigmarole of finding TDC, I took the quick method. There are two points in a cycle (2 revs of the crankshaft), where the nick in the crankshaft pully lines up with the TDC marking on the timing chain cover. One is TDC No1, and the other is TDC No4. So if you arbitrarily choose one of these, there is only a 50% chance of getting it wrong. So we set the crankshaft pulley nick arbitrarily against the TDC mark & installed the dizzy, with the vacuum advance mechanism parallel to the block, with the rotor button pointing to a point on the head, approx. between 1 & 2 cylinder spark plugs. Popped the leads on, in the usual 1, 3, 4, 2 firing order in a clockwise direction, looking down on the top of the dizzy cap. Hit the starter switch & there was a back fire, which woke the neighbours dog, and scared a few nesting birds in the tree above us. We had got TDC wrong ! Rather than line the nick on the crankshaft pulley up again, & then remove the dizzy & reinsert with the rotor button moved 180 deg, we simply pulled all four (4) leads off the dizzy. Connected No 1 spark plug to the opposite side of the dizzy cap (where no4 had been connected), then plugged the remaining leads to nos 3, 4, & 2 spark plugs, clockwise from no: 1 lead. Hit the starter, and away the engine went, and we were both home in time for dinner. From the time of the back-fire, to it running sweetly, took less than 1 minute. So if your ever in the dark, on a country road, & have to swap out a dizzy, this is a sure fire method of getting the timing right, without having to find TDC No:1 precisely. Hope this helps someone who is new to K engines. Cheers Banjo

Dave is spot on there. Quite common, & to be expected, when the rubber seals in the valve/tap are old & hard. Don't settle for a second hand one, as it will probably not last long. See if you can get a new one for the KE, but if not, there are plenty of aftermarket mechanically actuated ones, that are universal. Shouldn't set you back much more than $ 20, if these ebay listings are any guide. http://www.ebay.com....valve&_osacat=0 Cheers Banjo

Your predicament is not unknown. It's been mentioned on here previously. Here is a previous post with a few ideas & P/Ns, from about 3 years ago. http://www.rollaclub...7-in-australia/ Cheers Banjo

When you are mixing heads & blocks, which may or may not have been skimmed or decked respectively, the best way is to measure the length required. It's not hard, but is important. If the head bolt is too long, it will bottom out in the threaded hole in the block, with all sorts of problems. If the bolt is too short, then not all the thread in the hole is used, with also possible ramifications of thread failure. Clean the block threaded holes to make sure there is no rubbish in there. A tap helps. Measure the precise depth of the hole & note. Lay the head on its side & put a head bolt through the head, not forgetting to fit the hardened thick washer, under the bolt head. Put an old head gasket up against the head, & measure the length of thread sticking out beyond the head gasket, & note length. This length should be approximately the depth of the block hole, previously measured, less the thickness of 2-3 threads of the head bolt. I've always used this technique without problems. It would be advantageous to use new bolts. The bolts you have are probably 30-40 years old & you never know how many times they have been tensioned. Head bolts stretch, each time they are tensioned, which is why manuals always suggest replacing them. Hope this assists. Cheers Banjo

Hi Phil, That was very helpful, thank you. I read your post twice, & then went Wow ! I've always known basically how a a speedo works, but never taken a great deal of interest, but after reading your post, I grabbed the KE speedo, and took it off to the workshop and held it in the vice. I then put a pencil in my variable speed hand drill, & with the drill in reverse, drove the speedo with the tapered part of the pencil pressing up against the driven part of the speedo, where the cable fits. You can clearly see how it works, with the mild steel drum, pulling the magnet section fitted to the needle, until the hair spring reaction balances out, & you get a relatively stable reading. http://www.howacarwo...eedometer-works However, it was obvious, that any minor adjustment you do to the eccentric magnet position, to correct the speedo readings klm/hr, has no effect on the odometer & trip meter, as these mechanical plastic geared driven chains, are directly driven by the input shaft & cable, and not affected by any adjustment you make to the klm/hr reading. My need to correct the speedo is because I have changed diff ratio & wheel & tyre sizes. Mine is out about 8-10% approximately. My conclusion is, if I stayed with a mechanical speedo, and had it adjusted some how, as you describe, that my klms travelled & trip meter totals will still be out by 8-10%. To many people, this may not matter. However, there are many girls & guys on this forum, who like me, probably quickly check the trip meter & zero it, each time we fill the tank up with petrol, to see what sort of mileage we are getting. Each of us have a figure for our car for say city or country driving, for a full tank. If it then changes suddenly, it is a good indication that something is wrong, or my wife has been driving it & hammering it ! Ha Ha. :lol: :lol: Correct me if I'm wrong, but in the case of the electronic speedo, I believe the odometer & trip meter are are LCD displays, & would therefore coincide with the speedo reading if the calculation was done, over time between the two readings. I think I will stick with my decision to go electronic pulse speedo. I've sorted out the sensor; just need to find an electronic speedo mechanism that will fit the KE30 dash cluster. Anyone in Brisbane got a AE101 electronic dash cluster or speedo bit, that I can borrow or buy, to try it for size ? Thanks Phil, great insight ! Cheers Banjo

Fiddy job me thinks ! I just had a look at a KE speedo, and I can imagine after each adjustment, you would have to completely reassemble it, to test its accuracy. How many times did you pull it to bits & put it back together, before you were happy with the result ? Cheers Banjo

Thanks Sean ! All helps. I note that 3K head ID no 19, does appear in the Wiki, but not 39. It definitely is 39; it is not a "typo". We might have to whip the head off & take a look see. Cheers Banjo

OK, finally got it sorted. Found a website that shows how to test a Toyota SVS speed sensor off the car, with a wring diagram. The pin numbers on the AE101 sensor socket are as follows . . . Here are the testing connections. Pin 1 goes to +12V Pin 2 goes to Gnd Pin 3 is the output voltage pulses. I hooked it all up on the bench, and at first it did not produce any pulses. I then realised it was probably an open collector output, so I hooked a 10K ohm resistor between O/P (pin3), and +12V, and it worked fine. I then marked the shaft with a bit of white-out, & turned the spindle by hand, several times, and confirmed that the SVS speed sensor produces four (4) pulses per revolution. Trust that helps some else who may want to do this mod on their KE Corolla. When I find an electronic pulse input speedo dial from another car, that will neatly fit my KE30 dash, I'll post my findings here. If anyone knows of one that is a close fit, please post here. The KE30 speedo dash face is 90mm in dia. I guess, I will also have to insert a Jaycar speedo correction box in between the SVS sensor & the electronic speedo. http://www.jaycar.co...-manualMain.pdf Then goodbye speedo cable. That will make it a little bit cleaner under the bonnet. Cheers Banjo

I've just got around to cutting up the AE101 SVS speed sensor I bought on ebay, so that it fits the KE70 5 speed gearbox speedo drive. I'm now ready to test it, but can't find anywhere on the net, what the connections are for this unit. They will be 12V, GND, & O/P, but don't know which is which. No markings on the plastic socket. Can anyone help ? Cheers Banjo

Anyone know what engine, a K series head with ID number 39 (in casting between spark plugs 3 & 4), was fitted to ? No 39 is not listed in the Wiki. It is currently fitted to a 4K engine, I was looking at this afternoon, which has a few issues, one of which appears to be very high compression (about 180 - 190 PSI per cylinder). I'm suspecting it might be a 3K head on a 4K block. The engine runs on badly & is "dieseling". The engine is also fitted with a 3K dizzy. It has what looks like a carby without a fuel cut-off solenoid, so I suspect it might also be off a 3K. Don't know the history of the engine mods, so it's a bit hard to make a call, without stripping it down & working through all of it. Thanks ! Cheers Banjo

OK. Managed to find some in OZ. It is marketed here under the name ARDROX 2526, and comes out of Bayswater in Vic. Same formula as Tergostrip. Have been contacted by the Chemetall Qld rep here in Brisbane, and I have a 5 litre can being delivered to me in the next few days. I'll let you know how it goes. Cheers Banjo

Hi Oliver, Hmmm ! Rings a bell. Once had something very similar occur years ago, and turned out, it was as Dave suggested above. A perforated diapham in the fuel pump, was allowing fuel through to the lower side of the pump & into the sump. Unlike the press metal can fuel pumps on some Rollas, yours is the diecast model, that can be dissembled easily. Not a very hard job to take the fuel pump off & dissemble & check. I'd be doing that before anything else, as the drop in fuel economy was sudden, if I read your post correctly. Cheers Banjo
