Recently after getting the car on the road it developed the issue of oily smoke. Suspected valve stem oil seals were replaced and the issue is still there The engine was got used, wossners pistons, pec rods, 1.4mm headgasket. Sump has been off and no play from bearings up and down or crankshaft float. Compression test showed up 135 across 3 and 130 on one, does this seem OK ? Thought if rings would be constantly smokey on idle etc and would be a bigger difference in compression Breather set up consists of a rw developments catch can with race spec rocker cover, I had the lines off and didn't seem to make a difference so guessing it's breathing ok. Car doesn't seem to be losing any coolant. Anyone any ideas what else to check or what it could be ? Turbo kit was on it new it's the billet Garett gt20 from WEPR, has been checked as yet for any oil. From memory oil pressure at idle once warm is around 12 - 15 psi but would need to check this as can't really remember. Think I have covered everything
