Excessive - intermittent smoking on track


Model: C4S, Year:2002, Mileage:75000, Type of use:Both Street & Track
Replaced AOS 2 weeks ago. Still intermittent smoking in paddock start-up and on-track. Happens once or twice every 8 - 10 laps during first or second lapping sessions.... bad enough for black flag. No apparent pattern, other than seems to happen only when oil is at top level. Left track, drove 75 miles home trying to replicate with no recurrence. Completed engine oil analysis, clean results.
