Car idles like crap, every once in a while fights me on startup, and the big issue is that it now smokes heavily with oily blue smoke after every time I boost.

Sometimes when I boost only a little, ie. passing on the highway, its fine...but whenever I boost more then a small ammount and often even when its a small ammount the smoke billows when I let off the gas. It then clears up after a little while of gentle driving.

When I drive normally/gently there is no smoke at all, no smoke at idle...when it does idle.

There is ~20k on a rebuilt by Rx7 Specialties in Calgary.

Not sure what it could be, Oil control rings? OMP? Turbo going? How do I check if the OMP is fuxxed? And would checking the shaft play of my turbo all I could do? in and out or latteral play?

I searched but didn't really find much that helps.

Thanks guys.

as your rpm goes up, your oil pressure goes up.

are you sure its boost dependent, or rpm dependent?

Sounds like the oil seals on the turbo are about to go. I'd say pick up another one off someone here on the forum and try it out. Their usually under 100$ used from most of the ones for sale on this forum.

Did you cap off the crankcase vents on the middle iron or the oil filler pipe? Those are designed to prevent smoking due to crankcase pressure.

yup make sure at least one of the nipples near the oil fill tube isnt plugged up. and take off an intercooler pipe and check the insides of it to see if its oily, if it is then i'd suspect your turbo.

i wouldn't buy a turbo from someone else unless its freshly rebuilt and the rice is right. You should just get your turbo rebuilt.

Has it ever had a rebuild?

I agree that you should get a turbo that is already rebuilt with some proof. Though if you want you can always get any turbo thats not totaled and send it to BNR.

If you take off the intercooler pipes it will only check the intake side not the exhaust side. I would take off both just to be 100% sure. Some people say that if you are burning oil, and the shaft of the turbo has some play, the turbo seals are weakening which is not 100% positive.
