Ok done some tests with oil residue in inlet. Car starts as usual. Smoke on warm start, almost on every time after he sits for more then 5 minutes until it gets totaly cool. So It's probably not PCV. Not worth money to replace it or buy oil catch can. Must be the valve steams and valve guides. AVCUPRA290 does your car reps get unstabile when he puffs? For 1-2 sec?
