OIL INSIDE INTAKE MANIFOLD
This last weekend I was cleaning my engine bay and I removed the intake air hoses to clean them out good and check my trhotle bodys for cleanlynes and I noticed that there was motor oil all around the inside of the throttle bodys and the intake manifold.. Could this mean that my turbos are going bad, already bad, or just leaking.. I don't really smell a "metalic" cent from the exhaust. But then again I'm not going to sit at the rear of my Z smelling the fumes to see if I can smell metal or not. Too much of an unhealthy buzz..

Re: OIL INSIDE INTAKE MANIFOLD
Thanx for the prompt reply.... So, aside from gunking up everything with oil, the turbos should be safe long as there is oil still left in the engine to cool them right? Next question; What can I do short of replacing the seals (massive pain) to stop or lessen the seals.. I could try and see if anything is loose but if not that would a different type of oil work? If so What kind? Thanx alot in advance for any sugestions...

Re: OIL INSIDE INTAKE MANIFOLD
There is nothing much you can do. Just be sure to do the turbo cool down process after you driver (let the car idle for 60 sec. after driving). Not doing this after a hard run is the main cause of turbo damage. And be sure your not running yourself out of oil. On my single turbo Talon, the turbo was blowing through about 1 quart of oil every 1000miles when the turbo was about gone.
One way to test your turbos is coast down a long hill at high rpms (5k rpms) dont give any gas. If your an auto you may have to put the car in 1st. At the bottom of the hill floor it, then check your rearview. If a large amount of smoke blows out your turbos are nearly gone.

Check your intercoolers and inspect both from the turbo inlet side. If there is a considerable amount of oil build up then it is for sure 100% that your turbo oil seals are bad. I'm still new to Z32s but if the PCV hose connects directly to the intake tube just before the throttle bodies then your in deeper doodoo than you thought. I'd rather replace turbo seals than piston rings.
My 86 Celica GTS with a 2.0 3SGE (non-turbo version of Alltrac engine) started gathering oil in the intake and throttlebody as well but I had no turbo to spit oil into my manifold. The oil was coming from the excessive blowby exiting through my PCV which forced alot of the oil in the cylinder head to fly through the tube. The piston rings were so shot that when I disconnected the PCV tube connected to my T.B., gasses/air could actually be felt blowing from the little 5/16 hole.
It was so bad that if I squeezed the hose shut for a few seconds I could make a Blow off valve noise when I released. The condition progressively worsened and my rigged Gatorade oil catch had to be emptied after every full tank of gas.
I rigged the oil catch because the excess oil started building up in my intake manifold and began soaking through the gasket. The oil catch also prevented me from witnessing the horrifying blue smoke trail from my exhaust. It's pretty embarrassing being called the "crop duster" during your second lap in an autocross. In addition, oil soot caked my rear bumber and stained the paint.
I never bothered to check compression because the problem was too obvious. I knew my engine lost compression when I would only inch away from 99' Civic SI's. Back then I was in denial therefore I just tried to convince myself that the damm Vtec motor was built with cams, high comp. pistons, etc...
If I were you, check your compression just to be on the safe side even if your engine "feels like" it still pulls. Seat of the pants dynos are extremely deceiving!
If good luck favors you your rings will be fine. Either way, your gonna have to dump some cash into resolving the problem for preventive maintanence reasons. It'll be cheaper to empty your pockets on the turbo seals. Have fun troubleshooting!

Re: OIL INSIDE INTAKE MANIFOLD
Ok guys!... I cleaned the whole inside of my intake manifold and I noticed that there was no oil coming in from the hoses themselves...... UHOhhh.... I'm going to keep a close eye on it and see if I can close in to where the oil is coming in from... I hope it is not as bad as donkayroo proposed.. Tell you what.. She runs better now after the cleansing.....
