So the motor is turning over but the dizzy isn't?

What do you mean it's stuck? don't tell me you tried to turn it with a screwdriver while the engine is in the car?

what do you mean? i turned it over with a socket on the pully and i took the dizzy cap off and the rotor isnt turning?? and its sitting right down in the slot??

Ok, cool. When you said that it's stuck, I thought you might have taken the dizzy out and tried to turn the drive with a screwdriver - which would be very difficult.

 

If you're certain that the dizzy has engaged properly, I'd put it down to two things:

 

1 - Broken the tounge off the dizzy driveshaft

2 - Snapped a timing chain.

 

Have you had the car running and it's just stopped working recently? Or is it a fresh build?

guy i bought the engine from said it was a fresh rebuild. i had it running but when it was a had to keep my foot flat to the floor then it died and wouldnt start again!! i tryed to jump start it and it turns over but the dizzy still doesnt turn.. snapped timing chain?? how hard are they to replace??

[philbey]

Ok, something is defintely awry then.

 

First step, pull out the dizzy. it's only a 2 minute job, but if you're unsure, be very careful about the position of the rotor (mark it) when you remove it, and be careful not to turn the engine over while it's removed.

 

I would guess that it's the tongue on the end of the dizzy shaft that's broken. It's a flat tongue on the end of the shaft and I believe they can sometimes fail and break off.

 

If that all looks fine (put some pics up) then, long story short, you have something wrong in your cam train, which includes the oilpump as well. Given that the timing chain is the next "fail" point in the system, that's what I'd investigate next.

 

It's not too difficult, you just need to remove the front pulley and the timing cover.

 

Check the dizzy first and we'll go from there.

The tongue on the end of the dizzy only drives the oil pump. The dizzy itself runs of the crankshaft. Hence you can actually put a flat head down the dizzy hole and easily turn the oil pump.

 

Anyway...... was probably running shit because it had a very slack chain and was putting the valve timing out. Now that its stopped I'd say the chain snapped. Might have been a fresh re-build with an old chain (why would you!?) or you've been duped into buying just a regular old tired 4k.

 

Under $50 will get you a new chain and timing cover gasket kit. Couple of hours work and its fixed. Make sure you get all the marks lined up though so you don't put the valve timing out.

Worse part about doing it is the need to drop the front of the sump to get 4x of the studs out, Replace them with bolts when you re-assemble.

Damn I always get that mixed up... 2 pints at the pub and it's all over. :) :( :)

 

The funny thing is that's the second time I've made that mistake on this forum. Oh well.

 

Just listen to Taz, I'm going back to the pub.

[Taz_Rx]

That would be nice. I've still got an hour or so of "work" to do. Doesn't help when I'm typing here! :)

 

Those smiley pints look like Guinness Philbey........ go share one with a friend! :( .....

the tounge on dizzy is sweet, so must be timing chain, will start pulling apart. what marks do i have to get lined up?? do i have to take the hole sump off or just few of the front bolts?? thanks heaps guys

yeh no guiness' today but Red Tail Ale from Beer and Brau, another delicious dark one.

 

I just reread the other thread I mentioned it and it had the story of the time I wired my leads in reverse order....

 

lowtoy, if you need info on how to align the gears when you do the timing chain, someone should be able to get a scan of it.

[Taz_Rx]

There's some marks that line the chain pulleys up at top dead centre. Remove the timing cover and give everything a good clean to find them. Recommend not removing the chain and pulleys until you've found them all and know where its gotta go back....... actually thats not going to happen with a snapped chain is it!! Derrrr!! :) (there's mine for the day Tom!!! :) )

 

You only need to drop the front of the sump a bit, not take the whole thing off. Once you start doing it you should work out how this makes it easier. :(
