Put his boost gauge on too, still same reading maybe a little higher got up to 5 which I guess is normal. still makes me wonder why it was boosting to 6 and a half when I got it :S. Anyway on topic if done about 200ks and there is a pretty good oil film around the lid, and the scourers seem damp so it defianetely is working Link to comment Share on other sites More sharing options...

Kroozin Menace Donating Members 1,990 Member For: 13y 6m 20d Gender: Male Location: Sydney Posted 27/08/11 04:05 AM Share Posted 27/08/11 04:05 AM (edited) I would have at least a small teaspoon of oil in each runner in the inlet manifold aswell. It has always been there since I got the car and I had never figured out how it got there until now. After some changes to the intake piping I had to put a small engine breather filter on the front rocker cover breather which would be in front of the cross over.There is no sign of oil whatsoever on this little filter and watching it on the dyno I couldnt see any smoke come out either . I will be doing the back pcv valve with the extra 1 way valve to stop the boost coming into the catch can like JC807. Thanx for the gr8 wright up guys.
