I just finished installing my turbo setup today and now i'm having some major problems. The car is blowing smoke out of the exhaust like a bomb had just gone off. I'm running a garrett t4. I have two turbo's and I swapped both of them on there and I still get alot of smoke. My oil feed line is a braided steel -4an hose. My oil drain line is a 3/8 inch to the oil pan. Could the turbo be getting to much oil pressure? The smoke has to be coming from the turbo I just can't figure out why? Anyone had this problem? Any suggestions?

Sugestion: it could be sucking oil past the shaft seal of the turbo

That, or the oil return line is too small. Mine are at least a 5/8". Make sure they have a straight shot into the oil pan. No loops or kinks

Are the turbo's new and if not, how old and what's their history? The suggestions you've received from the other guys in this thread are all sound, by the way.

Either way, check the oil circuit pronto, and check your specs as to size of line, etc, and particularly check for a crushed liner or chunk of trash in either line. This can occur even in a steel-braided line, when something heavy smashes the line. The steel will rebound, but the liner is often composed of multiple layers and if the inner layer detaches and blocks part (or in severe instances, all) flow through the line, you'll have problems...

Also look at your wastegate and make sure its functioning properly.

Unfortunately, you may also have a motor problem seperate from the turbo(s).

I hope its something minor! Best of Luck!

(I once installed braided brake hoses and forgot to remove the plastic cap from one end. It was a late night thrash and I was too tired to be working on a car. Took a lot of effort to screw it on through the cap, but I did it. Left a perfect circle of plastic blocking the line. Not my shining hour!)
