Ok heres what it came out to: 145, 143, 130, 140, but theres a HORRIBLE amount of white/bluish oil smoke out the tail pipe. I think the dipstick raised a little, and it blows the PCV valve hose off. The PCV hose is loosely connected though. I am a little confused right now. I took the oil cap off and more than a normal amount of smoke came out. Its showing simptons of blow by, but the compression is good. Any ideas? This is a 2.2L VNT.

You can still have good compression readings and have worn rings. If you have alot of blowby, your rings are shot. The reason is simple, boost tends to find places to leak past if there worn.

What do your plugs look like?

They are white, the thing is there is so much oil consumption, I cant even see behind me through the oil smoke at idle. Theres no way there would be that much blow by at idle. I think the plugs went white after I had to drive it home while it was burning that much oil.

In that case, I would drop the DP, if its full of oil, the turbo is junk, as you suspect, :(
