Update 28.04.2010:

Need some Guru help, i got new sheilded wiring put in for the cam sensors etc right back to the ecu. Before doing that i had to remove the bonnet shroud and intake pipe to get access to the sensors.

Now i found alot of oil in the intake and have noticed that when the BOV opens there is a mist of oil.

The questions are:

is this oil coming from the seals into the intake?
Is there too much oil being pushed into the turbo (running -6AN)?
Will putting in another restrictor slow down the oil feed and stop this from happening?
Is there always going to be oil pooling in the intake due to the low mount turbo?

Now this oil is obviosuly going to be limiting the amount of timing i can push into the car befoe it starts to ping. I want to try and fix this any suggestions??

recommend you check your catch can plumbing.

Stace the catch can is not plumbed back into the air filter intake.

The oil is in the Intercooler piping on the intake side..

oil pressure to the turbo shouldnt exceed 45 psi from memory, (see garret documentation).

yeh thats right..

What im wondering if the oil is pooling due to gravity through the seals? or should the seals be able to hold the gravity fed oil??

Will a sump fix this problem i suppose also??

not knowing too much about the custom layout of your setup,

normally oil should be fed to the turbo via a hard pressured line from the back of the drivers side head, the volume of oil in the line is tiny, so highly unlikley oil is ingressing via that route.

the return line is normally gravity fed back into the sump via the bottom of the drivers side head also, although in your case i think you have a pickup pump circulating the oil back into the sump electrically? if so, providing the pump is evacuting all the oil both during operation and after your engine is shut off then you shouldnt have any pooling or return pressure issues, that is of course that the return point of oil into the engine is higher then the cold oil level of the engine.

Stace,

yep u are right we have a very small braided line going from the drivers side head to the turbo inlet line. Then it goes back to the drivers side head i think its -6an line via the pump..

The pump goes for 3mins after the car turns off. But it seems on some occasions that the exhaust still smokes and oil somehow gets in..

Is the oil line always full?? or will the pump suck all the oil back into the head and leave an air gap?? could this air gap be causing the problem??

Im thinking the only way around it is to make a mini sump??

Dry sump?

The porsche flat six runs complete dry sump for the block and ties in the twin low mount turbo's. Might be something worth looking into.
