Exhaust smoke

It may appear obvious if the mechanic looks, but a few dobs of liquid paper on cam cover bolts would be a good start.

as above, put a dab of paint/liquid paper whatever on a couple of bolts.

Exhaust manifold is probably a better option, a rocker cover is easy to remove and he'll likely do that anyway.

The exhaust manifold is somewhat of a bastard of a job, and needs to come off to allow the head to be removed, to then allow the pistons to be accessed, which need to come off to allow the rings to be changed.

Frankly, it's a decent sized job he has to do.



you'll find the bolts on the passenger side of the engine, holding on the exhaust manifold as shown in the pic above.
(you may have a tin heat shield over your manifold, but from memory the top bolts are still visible with it attached)

Don't do this. Your relationship with the seller may not be the best, but a bad relationship can always get worse. Your best interests lie in him doing the best job he can, p!ssing him off by marking bolts will not achieve that. You are better off asking him if you can have a look after the head comes off - you may even learn something.

It's irrelevant anyway, if the work isn't done, the problem isn't fixed, you escalate the complaint; if it is done, and it fixes/improves the problem, it is pointless.

If it is done, and the problem is not fixed, maybe the rings were not the problem after all (valve guides/seals?). Just because one mechanic makes a diagnosis doesn't mean he is right.

This whole saga sounds a bit off to me. Apparently there was no problem until after the service. So what changed - what sort of service was it? Is there any other way oil could be getting into one cylinder in (it seems) a big way? Is there any sign of fresh oil leakage around the head - valve covers, plug tubes, inlet manifold?
