Why do you need a new timing cover?
Mine has a hole in it on the inside near where the seal sits. It doesn't leak but since its coming off it will be good to sort it, if i can.
I looked at Devcon but its $129 and only handles 120deg. Probably have to see if i can get this one off at the wreckers. But like i said not sure if the car its on is belly in the mud like most there or if it has been jacked up. I can't tell from my wreck if i need the sump lowered to get the timing cover off as i cant get the balancer off. The bloke makes you pay before you even remove a bolt so i could get part way and not get it off.
Have a look tomorrow I have a good Buick in the shed but rather keep complete the amount I’ve scrapped over the years lol
What sort of wrecking yard is that clown running ? I've never ever heard of that protocol !
I know it drives me nuts.
Mentioned in my build thread i have the engine out. Turns out the engine is off a VP. Therefore no good won't work in a VR as the engine is different.
Not sure how the bloke who previously owned the donor wagon had it running but will definitely cause issues with my 94.
Well they are different but they aren't kinda deal. Mechanically they are the same bar some minor variances but that won't effect how the engine runs. Where the big difference is as I understand it is the electrical side which is why the VR engine has the cam timing sensor. The original V6 runs on batch fire injection (all 6 injectors pulse at the same time and you have fuel sitting waiting in the cylinder port for the next intake cycle. On the VR they went to split batch injection and it fires one bank at a time I believe and hence the reason for the cam sensor as the PCM needs to know when No1 cylinder is firing to start that sequence. If the cam sensor signal is missing the engine should still run but it will revert back to the original batch fire system. A VP engine in a VR should work as long as you use the original VR loom as it has the cam sensor wiring and also the injector wiring is different.
Yes the cam sensor is the issue. Swapping the harness is a lot of work. I have a sound engine already, just a knackered timing chain. This engine is an unknown. Sump and rear main needs doing as probably does the manifold. Probably the same cost as repairing my existing engine.
I will compression test it and try to flog it as a VP with good comp if it checks out.
I would fix what you have timing chain and a few gaskets are simple enough. IF it was really low on comp in one cylinder it would be a different story.
And that's it, the VR engine has good comp, good oil pressure and with a few hours work and $200 in parts it will go for a while yet.
Hey Losh,I may have a timing cover for you.
Finally managed to lock my spare motor up to be able to get bastard bolt out,my compressor wouldn't cut it (not enough flow?)
but a 3 foot bar did.
Anyhow it's off of an auto 3.8 Buick so has cam angle sensor.
Going to try and put a photo up then I'll go see if I can get a postage quote.
If got a pinhole in timing cover try KneadIt epoxy from Bunnings etc
Used it a few times with surprising results.
If it works all good & if it doesn't change cover.
Nah mine just has a chip in the back near the seal. Looks like a previous owner has gouged it with a screw driver when removing the seal. I found out I can probably have it welded fairly cheap. Or I can use those brazing rods mentioned and fill it myself. Just need to se if BOC sell them.
Engine should be out by now. Hopefully i will be right to collect the trans this arvo, ready to have the servo fitted in a week or so.
I should know exactly what the engine issue is come Monday when he tears the engine down.
Bit of an update timing gear is off and the chain was pretty bad. The boss said to the bloke I spoke too, who sits in the office that he has done a few and this was probably the worst chain he has seen as far as wear goes. So here's hoping that the rattle will be fixed with the new TC kit. Guess if not it needed replacing regardless. Hoping to order parts today and have the engine reassembly commencing maybe early next week, depending on his workload.
She'll be purring like a kitten in no time, chain is easy.
Yep and with new rear main and rubber sump gasket I won't be having to clean underneath once a month.
