smoke from turbo area
My car smokes everytime it is at iddle, and when i turn it off. It looks like it is burning oil because sometimes there is evaporated oil on the inner hood of the car. I am still boosting 10psi and i don't feel any loss of power. I did notice that the oil is running out fast and i have to refill it every once in a while. What do you guys think?

my car was doing the exact same thing...appears it's smoking from where the turbo and engine mate...
plus huge oil pan/rear engine oil seal leak, plus some oil leaks near the turbo area, on top of that, a blown pulsation damper that sprayed fuel everywhere and maybe damaged fuel pressure regulator...and a non-operating 2nd turbo...engine & car has 125k on it though...
drove with fuel problems for about 4 months...then finally couldn't stand the gas smell anymore...so pulled my engine last nite and gonna fix everything...maybe will even rebuild engine.

Fuel leaks in the engine bay of this car like dripping gasoline on a lit candle. You are very, very lucky.

dgeesaman...after reading about all the engine fires...i do feel lucky!...still wished i had read up on the fuel smell earlier...really was driving like that for at least 4 months!
mazda_rx7_r1...i just found your problem...i'll bet anything it's the same as mine...after removing the LIM, found the gasket between the LIM and engine block cracked, on both the left and right end of the engine block...i believe this happened under boost!...the only way to fix your problem is to replace the gasket...tightening the bolts with broken gasket won't do you any good.
you see smoke only during idle because of the exhaust recirculation action...when the UIM is under boost, you can't see the escaping air because it's colorless...
as for oil leak...front and rear engine engine seal broke, plus leaky oil pan
good luck

In any case you could start by removing the lower intercooler pipe and looking to see how much oil is blowing through the intake. If your turbos are shot this would explain both the smoke and the leaks. Do you make a big cloud of smoke when you get on the boost?

I'll see 80 for a brief moment at start up, on a warm engine 60 psi tops at full boost. The FSM says minimum 50 psi @ 3000 rpm. There is an oil pressure relief valve though I think its in the oil pan, check out the FSM.
Does any one else see 90psi? I'd been advised by a turbo rebuilder that high oil pressure would cause leaks.

Yep. I had the same problem you are describing and it turned out my turbos had a bad seal. pissing oil all over the undercarriage, and smoking all the time. Had to use a quart every 50 miles if I needed to drive it. Needless to say, I never needed to drive it lol

I'm trying to determine what is normal oil pressure at WOT, max boost. I'm wondering how many leaky turbo's are caused by excessive oil pressure. Does your turbo leak oil internally or externally?
