Re: Smoke and a rattle...
Hi, did you do a compression test before you pulled it apart ? that will have told you if the valves, pushrods, etc were doing their job.
The smoke issue sounds very much like turbo, ie, stop/start smoke at idle. or fine when cold and then smoke as it warms. the tick could be un-related. have you checked the turbo shaft for play ?
Re: Smoke and a rattle...
it's also worth looking at the manifold gasket while the head is off. they can cause a tick if it's burnt through on an exhaust port, which they do often if it's an old original one.
Re: Smoke and a rattle...
as scoff says a shame a compression test wasnt done i would still be inclined to whip the pistons out and check the rings just incase

I did a compression test and all was equal across the 4. The ticking noise is like a piece of metal tapping the engine assembly. I'll check the exhaust manifold gasket. There is no play in the turbo shaft at all; any other clues if it's letting oil through?
Cheers

I'm now really starting to think that it is the turbo causing the smoke but what about the noise? Well, it's flywheel end and i did rush to change the clutch before I took it on the track and the noise is coming from that end... Hmmmmm... I wonder... What damage would running without the vacuum hose cause bearing in mind I only did a few laps with it popped off?
Cheers

does the noise go if you press the clutch in could it be the release bearing

No, noise is there all the time... It really does sound like something metalic 'striking' somewhere. A few people have had a look at it but couldn't really say what the noise was.
