Foiled by blowing oil again.

Your location....sounds like your right next door to me!!
Had to change my location too....I'm a copycat.

Don't mount the turbo so far back and the more practical method would be to run a smaller line to increase response time and signal. A good breather like one included in the kit, plus and air/oil separator should eliminate most if not all oil entering the compressor.
I am not sure that these little oil seperators that I have now can flow enough volume to keep up with what the valve covers are producing under boost.
Maybe this big ugly thing I have can seperate enough oil from the waste crank fumes to work.
If you don't get all the oil out of the air to the turbo inlet that means oil mist all over the MAF unless you are SD tuned.
I agree that the turbo's inlet is the only source of vacumn under boost, which is when we need it. Off boost there is very little crank pressure.

try this !!!
first try a compression test , make sure is not a head gasket !! and make sure the lines of or crankcase are not being pressurized . the lines should go in just before the turbo so it's sucking it out !!!

On top of that his engine is a little higher quality build than a standard GM 4,8, 5.3, or 6.0.
I don't think these stock engines were ever really designed to take boost, especially over 5-6 psi.

Oh ya, I safty wired my oil cap back down and went out for a test mission.
Blew the cap up some and still leaked oil. Still layed some really ugly darkies all the way through first and little bit into second.
I think I'm done for the year as far as getting to the track anyways. Time to fix the problems.....

The suction you are tlaking about may be what vanilla is saying.
