Gentlemen,

I noticed a small valve cover oil leak, on exhaust side.

Car has 133k miles, original PCV, sees synthetic Amsoil 5w30 and lately 5w40 for last 3.5 years I own it. Camshaft seals are not leaking (they are new, in fact - replaced together with VVT clutch). Area around oil filler cap looks oily too, engine develops a good vacuum on idle revs, checked at oil cap and oil dipstick.

Is it a part of PCV clogged, the one responsible for high revs vacuum? Car had a bad oil change history, VVT clutch died, VVT solenoid was very dirty. Now it has all my love and best oil replaced in short intervals.

Engine does not eat any oil between changes, nothing I can see. Unlike XC70...

Replaced PCV, was not bad at all. Will see how it goes.
