well i've been getting serious blow by (oil shooting out of crank case filter) for about a month now........went and had a compression test........all my cylinders are getting between 170-175, except cyl #3 which got 50!!!!!!!!!!! they said it could be a bad/bent valve. going in for a compression leak test to dtermine what is causing the low compression. a bad valve wouldn't cause blow by would it? are you guys getting excessive amounts of oil out of your crank case filter?? i mean if i punch it hard it will drinch my battery (area) with oil.......if a valve is the reason for my low compression but doesn't fix the blow by i'm just going to run a tube from the crank case breather and tap into my oil return line from the turbo.....should be easy.

Dude, sounds like worn rings at the least, perhaps a bad head gasket. The oil part, though.... that really sounds like a cracked piston. Sorry, dude, but i may be right there with ya before too long I can't seem go get my ride tuned right
-DarkOne I'm so bad, i should be in detention.

nothing is coming out of tail pipe out of the ordinary, when i punch the throttle nothing really comes out of exhaust.....idle seems fine for the most part once my engine warms up....

Join the club man, I'm in the mix of fixing my car with the same symptom. It started subtle on day, felt like the car was lobing like it was cammed up or something, by that night I noticed smoke coming from around the hood, took a look and oil was blown everywhere from my valve cover breather filter. I had 170psi on all except for 70psi from cylinder 1. After paying em nearly $400 just to rip it apart to see what was wrong with it, it turns out it was a crushed piston ring land (the groove where the piston ring sits inside the piston). So I'll put my money on thats the problem. Actually its easy to eliminate valves as a possible cause, just put some oil into cylinder 3, if the compression raises (temporarly), then its the piston (or rings), not the valves. Hopefully your cylinder wall isnt damaged, mine was lightly scratched but can just be honed out. If your gonna upgrade the pistons (mine as well while its ripped apart)remember HRC (JE) pistons are require you to bore .020 over stock. Today Im calling JE and 2 other places that make custom pistons to see about making them to my car's specs/current measurements. (its cheaper than having your block bored unless you do all the labor work yourself) Well hope this helps, anymore info I find out Ill let you know if ya need it, goodluck...
i just recently turned it up to about 8lbs of boost since i finally put my centerforce DF clutch in.......now this. before clutch i could only run aobut 5lbs......
I can't seem go get my ride tuned right
