Excuse the old shared_user name....havent been on here in 6 years...
Im on my second turbo setup and now im seeing oil comming out of the exhaust? No oil in IC piping. Had to get smaller jet for oil inline feed because sendng more oil then could drain which resulted in oil commin thru seal of turbo and out exhaust..Not sure of my problem..bottom end built, have crankcase ventilation....replaced only turbo and manifold. Cylinder walls look fine from pulling spark plugs. I hope the seal isnt bad on exhaust of turbo... Only smokes when shifting around 3-5k..does not smoke when on it hard?? Does it bad when idles down road and then give it a little gas.. Im confused..oil feed line is a dash 3 line with reducer and drain line is a 1/2 inch hose near the bottom of oil pan(maybe need to be tapped higher?). Have crank case ventalation. I never had this problem with old turbo setup and like i said only changed turbo and mani...Ive had compression check and leak down about 3-4 years ago on old setup and checked good but new setup has less than 20 miles on it..ive done everything i could think of besides tear down motor..Every one says is some kind of feed or drain issue but dunno where to begin cuz didnt do it before????? Thank you for your help

Crankcase ventalation consist of hose goin from valve cover to can and hose comming from the nipple under intake mani on passenger side of car where the stock breather box would go....also i have a hose goin from the nipple of the intake mani with check valve running down to a tee with two hose connecting from the block on the drivers side??? maybe all jacked up???

 

pull the turbo off and check if theres oil in the inlet of your turbo and if the inside of your t manifold is oily if so thats your motor, if its oily after the exhaust wheel then its the exhaust side seal in the turbo
