Oil Leaks!!!

OK, yesterday I replaced my oil pan gasket for the 4th time (or is it 5th) and it got blown out within 10miles, running 14lbs of boost... Every seal on this car has leaked and been fixed at some point in the last ~10k miles (11months or so). Current offenders are the oil pan gasket, and what appears to be either crankcase vent (oil air seperator), or drivers side balanceshaft housing.
I need to figure out why all my seals are leaking, running out of ideas here. My best guess is that the air/oil seperator is clogged, please help me, this is VERY aggrevating. Compression is good, so I don't think blowby is really an issue.
Thanks
Ahmet

The only way the oil pan gasket will blow out is either by poor installation or excessive crankcase pressure. 14lbs (.96 bar) of boost is not much above stock anyway. You may be having a blow-by problem.

Have you checked the breather system? you need to be sure that the crankcase is not being pressurised by an incorrectly assembled breather system.

I doubt the oil pan gasket installation was faulty, I also don't think I have an 'excessive' blowby problem. It hasn't been long since I rebuilt the engine (dirty rebuild though), and the compression is only .5psi off spec for a new engine. What I'm guessing (hoping, oh god!) is that the [problem comes from a clogged/malfunctioning breather as the oil pan gasket is not the only seal/gasket that's leaking or has leaked.

Is there any way to check the air/oil seperator +breather?
Thanks
Ahmet

I have never been able to stop the oil leaks in mine either. Right now I am leaking where the head meets the block near #4 but on the side. It has been coming down the outside of the block for at least a year. I put a new head on it about 4 years ago. I also think I am losing some from the rear of the oil pan gasket but that could be coming from above. It is aggravating. I was very careful with the pan gasket when I did it last January. I also find oil at the end of the three metal lines that go across the top of the block under the intake. I suspect the connection where the metal meets the rubber is leaking a little because that rubber hose is wet. I plan on removing the intake after the Charlotte DE. I also have a little oil leaking from where you fill it. A drop forms on the O2 cable.

Other than by disassembling it, no.

I am getting ready to do my whole vacuum air/oil seperation and associated seals.

there is a cork seal at the back of the engine, at the end of the
?cam tower? the thing that says porsche on it, haha i'm an idiot i know. That seal goes bad a lot and leaks a ton of oil, it drips down the back of the engine and makes it look like its the oil pan seal, i may be wrong but i bet some of you guys have that problem and not the oil pan, that cork seal get hard and brittle and just falls apart

I'll check the cap at the end of the cam tower tonight. I resealed it about 6 years ago without a gasket - just used Permatex. Last time I looked (about 6 months ago) it was not leaking. It would be nice if that is my problem....
