Help Needed. Ring Gap Anyone?
Well. First posting on here, and it is a long sorry story.
My 156 2.0 TS hates me. Trying to get to the bottom of it belching white smoke and knocking like there is not tomorrow.
The head-gasket went on it and I fried it. This was caused by damage to the head from a repaired cam-belt break (before I owned it). The chump who fitted the head somehow put a dent in it between 1 and 2 cylinders, thus the gasket eventually burnt through.
Anyway. To cut a long story short, I now have the head off for the third time. My thoughts were that maybe I had knackered big ends from hydraulic lock, or rings had it from overheating, causing oil burn and piston slap. Well, everything looks fine, so really fed up with it now. Ive had Variator apart - like new, tappets stripped cleaned and primed, now pistons are out.
No signs of slap, but scavenger rings are pretty gooed up, so maybe it is slapping, and maybe the smoke is unrelated to the noise?
Before I waste any more money on it, can anyone advise what the ring gap should be?
