Engine smoking

Post by John@mcr1 »

Hi,
Bought a GTV6 1983 from South Africa which I imported to U.K. last year. Now I have it on the road I’ve discovered it smokes quite a bit, especially when I stop at traffic lights then set off.
It has a receipt for recent works carried out on engine, rings valve seals gasket etc before I got it. I wondered if the problem could be the rings have not seated properly as it hasn’t been used much since rebuild which was probably 2 years ago.

Anybody who can shed any light on it would be appreciated?

Regards John

It sure sounds like valve stem seals are leaking.

Brian’s probably right. If it’s the rings, then you should see constant blue smoke.

Could be all of the above and it could also be bullshit receipts.
Do a compression test on all cylinders first.

Hi Kevin, the valve stem seals have been changed to the green ones as they were the black type. Unfortunately still smoking so my mechanic is looking into it at the moment. I will update you when I get some news.

John did your mechanic check how the seals fitted when pressed on as I mentioned there were some guides exported to SA that were a touch smaller in diameter who knows why !! So my mate had this nightmare issue a few months back. As he was not a mechanic he assumed all was good with his new green seals until he checked again and they had all fallen off. If he takes manifolds off what does it look like on the back of the valves ? I assume all the compression tests, leakdown tests were all good on this fresh build.
