Hi matey! you may have seen my bus at Chris' house when you were out mapping, I entrust it to no one else! lol
If it puts your mind at ease, ask chris to show you the dvd of my old monster on the dyno, it 'misted' too at high boost/rpm ie 29psi on decompressed forge build with serious headwork. The issue indeed lies with the PCV, the oil is getting pumped into the head at pressure, then the cams are obviously doing their thing at an equal RPM, plus the cams are gear driven in there too, so theres quite a bit of the slippery stuff getting thrown about, so its innevitable some manages to find its way out! Fear not tho! my engine is STILL on the road seeing good use, and has had a few owners, so I wouldnt be concerned.
As wise Confucius say ' its all in the tune daniel san '
or was that mr Miagi
