Ok so I have a 95 na-t with a PT-52 turbo, and i have been noticing lately that there is white smoke that is basically pouring out of the exhaust. It only happens when either i come to a stop or when im driving with a little throttle and then let off and get back on it. It's never happens when im on the throttle. I know its not coolant because it doesnt smell like coolant. It kinda smells like oil, and i have been losing oil more than ordinary. Any help would be great.

Check you I/C piping to see if there's any oil in them from the turbo. Or perhaps your valce seals are going...how many miles on her?

Well if your I/C piping is all clean of oil then that pretty much rules out the turbo. It may be coming from the head, i.e. Valve seals. easiest thing is to check the I/C piping and work your way to the head. 106,000 can be valve seal territory...

Is it possible that it might be leaking out on the hot side of the turbo. Does oil burn white if its hot enough?

I think you need stem seals..... :rofl:

j/k

If you have no play in the shaft then you most likely have a blockage in your drain line. Verify that your oil drains into the upper pan and not the lower. If you have shaft play you need a new turbo, possibly even if you don't have play. Turbos have no seals per se, they just don't leak due to pressure differentials, a blockage on your drain line will force the oil to leave from places you're not used to seeing.

You're also going to need to clean your FMIC, piping, etc. Go buy lots of brake cleaner and start spraying.....

it drains into the upper pan. i know this for a fact!!! he has a greddy type s bov and when it vents it makes a loud purge sound then the normal high pitch whistle sound that the type s normally makes. i wonder if the purge sound is actually compressor surge??? therefore killing the turbo..

the white smoke is not normal!! when i had the car it never did that ever, but since brad has the car it had progressively gotten worse.

Full synthetic oil burns white , check your plugs they will show you whats going on in the combustion chamber , if your a/c is dieing on you and not blowing as hot or cold as it once did , and u hear a "waterfall" sound behind ur dash when u start your car cold that may indicate a leaking Headgasket. That would also cause a crap load of white smoke. Looking at the pics of the turbo id say its time either rebuild or check your drain line. GL

I just changed the plugs and they all had normal wear. One had a little bit of oil on the threads but there was none on the electrode or anything. I am going to check the oil drain line tonight.

Sound like a turbo going bad to me. Mine did the same thing you described. Sent it to have it rebuilt = no more smoking. :)
