It was from one of your posts you put up when I was having issues with the rear leaking and putting another pcv on that I tried as a last resort the car has been perfect since, 2500km on the new motor oil, the same height on the stick not burning oil and plugs are clean running (EFI) . I feel everything has settled in as it runs way better now.Mine runs 70psi off idle once hot 50psi same as yours 1500rpm 70psi.
