Alright, I just did some tests and put on an aluminum AST on today. Compression test results were (using a piston tester) were consistent above 35 psi blips (while holding the release valve down for the 3 faces of the rotor) and an overall compression result about 110 psi in the rear and 108 psi in the front. I apparently have a rear main seal leaking and needs replacing.

My problem is while I was doing the install of the AST I removed my intercooler piping and noticed quite a bit of oil in the pipes. Can anyone explain to me why this is? Thanks in advance for any help.

A little bit of oil is normal. If the oil is excessive (as in, drips out when you up-end the pipe) then the seal in your turbo(s) is leaking, and will continue to get worse.

Alright thanks for the input! I will check that a bit later today. I was just wondering how much if any oil should be in the pipes because I was afraid my turbos were going bad. I will probably upgrade the turbo to a single turbo anyways, but I guess if this is that bad I will have to do it sooner than later.
