First and easiest thing to do is a compression test. Once you get those results post back. Don't get ahead of your self thinking about cost and such, one thing at a time. If you need new rings and don't feel confident I live in the area and have the means to do the job. First things first get that compression test.

I agree as well. If everything is good, turbo is next on the checklist.

What color is the smoke? Bad trubo or so much oil is getting to the turbo it's getting past the seals = blue smoke.

You will find out some more info when you pull your intercooler.

when it smokes its a thick lingering whitish color may have a blue tint to it but you can smell it, dosnt smell sweet, smells like burnt oil...there isnt any anti freeze missing and yesterday i filled the oil up and it smoked for about ten mins... by the time i shut the car down there was a good amount of oil at the end of the exhaust. well i have everything for the turbo install so im gona put the new turbo, injectors and uppipe in on fridaynight. ill post pictures of hotside/inside downpipe/uppipe when then come off. sat ill get the compresion test and post that also. ps ive taken the intercooler off before and there was oil in it.

Agreed do the compression check. And take the intercooler to a parts washer, oil will lower the efficeincy of an intercooler drastically.

If it smokes from the exhaust it's turbo.

If you do compression test do a leak down test as well, much more useful.

ok so i had the compresion test and leak test done this passed sat. my mic said everything was ok there. so i went alonge with the turbo injector uppipe install. my mic said that while installing the turbo he went over all the vacum lines to make sure everything was ok and found that the line going into my oil catch can was pinched almost shut. believe this was causing my boost problem...maybe unrelived pressure...as for the oil burnning problem, the hot side of my turbo looked like the inside of a fireplace or boiler that was burnning way to rich(caked with soot sorry boiler guy) dont know how to get a pic posted on here(if anyone knows please post). i changed the oil and will keep an eye on it but no more smoke..only one problem ihave a slow anti freeze leak from somewhere in the area of the turbo . cant see it from the top but u can see the anti freeze on the underboody...our turbos have a ati freeze line to them?

they're cooled with intercooler, and they use the engines oil to lubricate them.

Correct, they are cooled by the engine coolant (a.k.a., antifreeze) and lubricated with engine oil.

From the information manual
Quote:
The turbocharger is lubricated by engine oil branched out from the oil pump. To cope with very high speed of the turbocharger turbine and the compressor shaft which may reach a maximum of several hundred thousands of rpm, full-floating type bearings are used which can form adequate oil films on their inside and outside during running.

Further the oil supplied to the turbocharger also plays a role of cooling the turbine so that heat from exhaust gas does not get transmitted to the bearings

The turbocharger unit is cooled by engine coolant, which enhances the reliability and durability of the unit. The engine coolant from the coolant drain hose located under the cylinder head is fed by a pipe to the coolant passage provided in the turbocharger bearing housing. After cooling the bearing housing, the engine coolant is fed into the coolant filler tank through a pipe.
