Message	Do you have a full exhaust; DP, TP, CB setup? It has to do with the free-flowing nature of the exhaust. A free flowing exhaust will produce greater scavenging at the turbo/manifold/head at the end of the pulse wave and this sucks some oil past the turbine seal. Stock turbos are especially sensitive to this - I could speculate as to why but will leave it there. If you have the stock midpipes with cats, put them back on and see if the smoking goes away. If it does, the smoke is definately coming from the turbine seals. [ ashspecz.com ] [ agpowers@bellsouth.net ] Enthusiasts soon understand each other. --W. Irving. Are you an enthusiast?
