Tally Posted July 19, 2009 Report Posted July 19, 2009 (edited) guys what can you tell me from this pic below. 5K, water in oil... Looks to have dished pistons? Basically had water in oil so suspected it had the usual blown head gasket but pulled it off today found water in no 3 cylinder... couldn't find head gasket failure... although I'm not an expert... So just would like to know if you guys can sorta put me in the right direction of pin pointing the casue of this... oil is milky az... pistons 1 s clean, just carbon deposits, piston 2 looks not bad, piston 3 doesn't look too good with water in it and burrs and scratches on it... piston 4 is really black and filthy... gonna get head skimd tomorrow... should get it pressure/ crack tested aswell??? if ring in number three was gone, wouldn't it have oil in it and be blowing blue smoke? cheers in advance Tally Edited July 19, 2009 by Tally Quote
philbey Posted July 20, 2009 Report Posted July 20, 2009 Tally, I just had my head gasket go the other day as well, and I found no signs of head gasket damage, but I had nice cappucino foam on my coolant after top up (after blowing a heater hose off and dumping all my coolant). Engine Builder told me that because I got it home and got the head off so quick (10 minute drive and off the next day) it's unlikely that I'd see any tell tale signs on the HG. Get the engine builder to take a good look he might reckon a pressure test is worthwhile. Milky oil is a definite sign of HG Fail. It may be worse, like a cracked head or block though, but just get the head looked at. Get some closer pics of this bore scoring Quote
Tally Posted July 20, 2009 Author Report Posted July 20, 2009 (edited) yea man dropped it off at Richardsons Engine Service around noon, rang me up at 5 saying its fully reconed!!! initially he said Wednesday. Now that's what you call speed of service... Pick it up tomorrow morning. Basically he said the head looks like it has been previously tampered with and the water jackets were way to close to the cylinders... So looks like he has fixed that. said he'd weld them to original size... He said to me he would pressure test it for cracks and get back to me if it was no good.. but looks like its ok as I told him initially to recon it if its ok. Pictures of top of piston and bore marks... wondering how to get all that dirt out? high pressure air gun? vacuum lol? Edited July 20, 2009 by Tally Quote
kiahn Posted July 20, 2009 Report Posted July 20, 2009 if there is dirt in the cylinder then try get it out with high pressure air. but i don't think that would do much good as it might have found it way in between the piston rings Quote
philbey Posted July 21, 2009 Report Posted July 21, 2009 If it's just the snot from pulling the head off, and you haven't moved the pistons too much, you should be able to blast it with air to dislodge while you run a vacuum cleaner in there to suck it up. Quote
Tally Posted July 21, 2009 Author Report Posted July 21, 2009 (edited) yea man thats what I did today. cleaned it all up vaccumed all the shit out. Cleaned top of the block/pistons and bolted head down to 44 FP / 60 NM soon to be twin SU powerhouse lol just need some fuel hoses and some T peices. might try PIRTEK...

philbey Posted July 22, 2009 Report Posted July 22, 2009 MM SU's. Where'd you get them, but em off here? One of the recent sets that sold? Quote
Tally Posted July 22, 2009 Author Report Posted July 22, 2009 yea got em off ke30 myles... been reading and doing research about them and turns out they are a unique carb style with only 4 moving parts. Should make tuning a bit easier... just waiting on the thermostat housing to head, gasket... no one had one, went to autopro, repco, sprints, motor traders... went to Toyota, slugged me $4 (:P) and have to wait till tomoro to get it from melbourne :wink: Quote
Taz_Rx Posted July 22, 2009 Report Posted July 22, 2009 Only time I've ever got one was in a timing case gasket set. Bursons etc don't have a listing for them. I just make my own out of gasket paper anyway - $4 for the whole roll. :P Quote
Tally Posted July 23, 2009 Author Report Posted July 23, 2009 (edited) ok engine put all back together today... basically ill explain everything... Drained milkshake oil fixed starter motor bolted intake/exhaust manifold back onto head connected all vacum lines, fuel etc Made gasket for thermostat housing and bolted it back on bolted up radiator and connect all hoses... Replaced spark plugs with newies... Filled radiator with coolant Filled engine with oil Checked over everything, tightened all clamps, bolts and screws and then the moment of truth... Started first go, one tappet is really loud, not sure why... got it to idle nicely though... basically I had white smoke coming out the exhaust and a fair bit of black water (black cause the exhaust is full of carbon?) Pretty sure it aint oil... Warmed it up to find that it was getting a bit too warm... checked the radiator... still cold... got to half temp, so shut it off then the thermostat decided to open I think as the radiator suddenly got real hot... top hose was hot but not the bottom hose? a bit of white steam was coming out of a rocker cover hole while it was running... Now.. I'm replacing the thermostat as its most likely faulty from sitting for about 5 months... now ive read in the FAQ that the water pumps don't like sitting for too long, but water out the exhaust aint a water pump problem... as said in my first post, no 3 cylinder had water on top of the piston... couldn't see any cracks in the block for it to be getting in from so thought it was head gasket... anyway head gasket is all replaced now and the head has been reconed and is all good... so not sure where I'm at... will replace thermostat tomoro... maybe it was just condensation? or maybe still had water in the exahust? what explains the white smoke? after reading, looks like I am burning coolant which causes white smoke? so basically I may still have two problems? burning coolant and oil/water mixing..? argh... maybe connect a oil pressure gauge? or water pressure gauge i dunno lol also just so you guys know, I had drained the coolant from the block, so when i filled it up again and started, coolant was only in the radiator and not in the block? and it decided to open when I shut it off? I thought the thermostat was the only way coolant could get into the block? can it get into the block from the bottom hose? Edited July 23, 2009 by Tally Quote
philbey Posted July 23, 2009 Report Posted July 23, 2009 Your white smoke (rocker) will most likely be steam. Keep in mind that your sump has quite a bit of moisture in it and as you warm the car up, this will turn to vapour and waft out of the rocker cover. Are you sure the white smoke out the rear was smoke, and not steam? Much more noticeable on a cold morning? It could have been oil smoke, perhaps you got a bit in the bores when you pulled it apart? If it is steam, you are getting water in the combustion chamber. Let the car idle for a while, but disconnect the tube from the radiator to the header tank (if you have one). When my 3K went, warmed her up and she started pissing water out of the overflow hose. Unfortunately for me, the water coming out was stone cold. Combustion pressure was pressurising the water jacket and pushing it out past the cap. Top hose will always heat up first, then the hot water has to pass through the rad and back into the motor before the bottom hose and the rad will heat up. You will most likely not see the cracks in the block if they are there. As the block heats up, the engine expands, crack opens up and that's when you'll see the combustion pressure leak. Quote

Much more noticeable on a cold morning? It could have been oil smoke, perhaps you got a bit in the bores when you pulled it apart? If it is steam, you are getting water in the combustion chamber. Yea must be steam... it evaporated real quick so its steam not smoke... nope didnt get any oil in the bores... Let the car idle for a while, but disconnect the tube from the radiator to the header tank (if you have one). you mean the overflow bottle? yea it got full!!! When my 3K went, warmed her up and she started pissing water out of the overflow hose. Unfortunately for me, the water coming out was stone cold. Combustion pressure was pressurising the water jacket and pushing it out past the cap. yea well mine got full... You will most likely not see the cracks in the block if they are there. As the block heats up, the engine expands, crack opens up and that's when you'll see the combustion pressure leak. damn... I was under the impression that its very rare that blocks crack and it would most likely be the headgasket or the head you know what I mean... The head specialist examined the head gasket and said yea it looks as if it had been leaking into the cylinder, and like you said previously: Tally, I just had my head gasket go the other day as well, and I found no signs of head gasket damage, but I had nice cappucino foam on my coolant after top up (after blowing a heater hose off and dumping all my coolant). Engine Builder told me that because I got it home and got the head off so quick (10 minute drive and off the next day) it's unlikely that I'd see any tell tale signs on the HG. Milky oil is a definite sign of HG Fail. It may be worse, like a cracked head or block though, but just get the head looked tomorrow I will replace the thermostat, take the plugs out see what they look like, maybe do a compression test when cold and when hot... if its 100% screwed I'm just gonna get a 13BT :y: Quote
philbey Posted July 25, 2009 Report Posted July 25, 2009 It could be a cracked head as well, you won't see it. Did your engine guy look over the head too? Blocks do crack, i've seen it before with K's. Quote
Tally Posted July 25, 2009 Author Report Posted July 25, 2009 yea I rang him up day b4 yesterday... thats why I gave him the head, to check for cracks, but he goes and recons it without my authorization... wanker lol well any car is running a heap better since yesterday, minimal steam out the exhaust... still burning coolant but way less then b4... doesn't overheat or nothing... just gonna drain the oil again, flush the engine with some diesel, and new oil and filter...

rob83ke70 Posted July 26, 2009 Report Posted July 26, 2009 very hard to get the moisture out of the sump by draining the milky oil. take it for a 20 minute drive on the highway, the oil temp will be higher than the boiling point of the water and the steam will travel out the crank breather into the inlet manifold and then out the exhaust, thus getting rid of it all... wouldn't stress too much about changing the oil yet, take it for a drive first. We have a small but significant amount of water building up in our catch can (hooked to crankcase) which is concerning me somewhat, I'm going to retorque the head gasket sometime this week when I get a chance, I'm a little concerned I have coolant leaking into the crankcase (the cylinder head was not very nice when I put it together) but I guess time will tell.
