Well the car had been sitting for a few weeks and before that rarely got driven. Due to my sister getting into a wreck in her Z28 i was going to let her drive my truck and i was planning on driving my dads 85 Gn for a week or two (until i get my 87 back together) Anyways after a round of mods (fixing exhaust leak, tranny cooler, new chip, gutting cat, changing fuel filter) andl after getting it all back together i started it up and it ran good. I let it warm up a bit and then after a while noticed oil smoke out the exhaust. It kept getting worse until i shut it off. I checked the PCV to make sure it wasn't causing it (blocked it off and it still smoked) Strange thing though, there is no vacuum from the PCV? The PCV is a newer delco unit and i cleaned it out to be sure. What could cause this? I also pulled the downpipe and noticed a little oil around the exhaust wheel, is this for sure the turbo or can a leak in the motor (valve guides, ring etc..) cause oil to be on the exhaust side of the turbo? the 3 random plugs i pulled were all oil fouled so I assume the its the turbo. If it matters the car is 45,000 on a rebuild, stock turbo, full ATR exhaust and headers , fuel mods, ported big valve heads, large cam of unknown specs and converted to 87 ECM, LT1 translator etc.. I had been fighting knock retard and overall slowness for the past few hundred miles its been driven.
