Hey guys so I had put quite a few miles on my chinacharger and it ran great and had no smoke or anything but after maybe 5k miles it started smoking a little. As the smoke gradually got worse I assumed it was the oil seals in the turbo so I went and bought another turbo and put it on and its smoking a Lot. Like James Bond style smokescreen. I didn't have an oil restrictor at first so I just out a 1/8" rivet in the line and it is still smoking.. Should I splurge for a smaller oil restrictor or???

Here's a video of the matter. Ignore the loud exhaust leak...

Even with a journal bearing turbo, some will need a restrictor. But that will depend on the amount of oil flow to the turbo, and the oil return from the turbo.
How many miles on the valve stem seals?
The extra head from the turbo, can cause the valve stem seals to get crispy and hard if they are high milage factory installed ones.

That is where I would start, the factory used a low temp rubber seal.
Get a good set of blue vitions.
Smoke on start up, stop lights and long idle periods, is commonly bad valve stem seals
Smoke all the time, bad rings, blown turbo seals.
Smoke on decell, bad oil scraper rings

I blew a head gasket due to me not torquing the head properly upon reassembly and it was actually worse than that. But I could be wrong. If you take the head off check it with a straight edge to make sure its not warped also. It just doesn't appear to be oil related to me. One of the easier checks to do is pressurize the coolant system and see if it holds, if not, your head gasket is blown. (Unless you have a leak somewhere else, obviously)

Well thanks for those comforting posts! I disconnected the turbo and lots of oil in the exhaust. Ran it and no smoke so it's not the engine. That makes me very happy. I put a smaller restrictor in the oil feed line and i'm going to see if that helps any. Kind of weird that it would do this with two different turbo's.
