Bit of a weird one, just after some thoughts really before I go off on a tangent.
It's an s13 Sr, had a brand new garret gt2560r about 3 years back and has covered approx 10k since. Currently running 1.2bar.
Issue I get is on track (grip, never does it when drifting or when driving on the road) when I lift off from high rpm I get a trail of oily smoke. Enough to prick the marshalls ears up.
The car doesn't use any oil, doesn't puff any out under any other circumstances, only when I lift off on track.
Engine has good compression and cylinder leakage results. The breather from inlet to pcv on the cam cover has also been blanked off.
Baffled as to what to look at first really. Drives fine on the road, only ever does it under deceleration when on track....
Any help appreciated!
