At the back of the engine there should be a pipe / tubo coming up from the oil filter mount to the back of the intake side valvecover, this pumps oil (excess pressure maybe?) into the top of the engine for it to trickle back down and lube htings up in general (vs whre it is pressure pumped elsewhere)..
at the front of thei ntake side valvecover there is another opening, this one connects via a hose to the PVC on the back of the intake manifold..
and on the exhaust side there's only one opening in the valvecover, this is supposed to go into the intake piping BEFORE turbo and AFTER MAF/filter. this can cause some oil to get sucked into the intake system, this is what catch cans are for. This is to keep the crankcase from getting pressureized one way or the other (this works in conjunction with the PVC).
is this how you have it hooked up? if your turbo is practically gone you could also be having oil going past the seals there and getting sucked into the intake there..
