Can anybody help a brother out? I installed egt and boost gauges, and noticed the presence of oil residue / small drip when removing hose clamp coupler goodie. Dealer said has had some complaints regarding this and was normal, but bring it down and we will make sure it's not excessive amount. Also he couldn't tell me where it came from or how it got there.
So is this normal, and where does it come from?

Signed, kinda worried
:help2:

I had a small leak on the intercooler lower hose- some residue is normal per GM - Dealer should have bulletin from GM. They put a sealer on the hose and retightened. Seems all ok.

the oil cums from the crank case vent tube it is run in to the turbo intake for emmishions reasons i will be venting mine to the atmosfear cuz i dont like all that crap in my intake.

Just found it myself and was a little worried.
