As you all know the Head and Block doesn't lign up properly as far as the crankcase leaving most of the "pits" of the head half covered by the headgasket.

I've been having some problems with a lil blue smoke, I've pretty much eliminated all the possibilities of from the block to the turbo. I've been getting slight oil residue on the turbine side, visible from underneath the car. The turbo has less than 100miles, Oil return/feed is excellent, PCV is new, etc.

Did not have any of these problems when I was on my LS or B16 and the previous turbo did not have any problems with the oil feed/return.

The engine is built, compression is perfect, no smoke during the initial break in without the turbo the first time around.

This leaves me to the last theory that the crankcase is becoming excessive and causing a restriction on the oil lines and is backing up on the bearings. I'm thinking of tapping in some 5/16 NPT" Hose barb fittings like on the endyn engine pics I've seen on the valve cover, to help alleviate the problem.

What do you guys think? Any ls/vtec guys having similiar problems?
