Compression Test

[MaddMatt17]

Ok, so I finally did a compression test on my car. At first I thought my HeadGasket was blown due to the fact i had a little bit of oil in my resevrior. Other than that there were no other signs of Headgasket problems, such as water in oil, or white smoke blowing out. I think the people that did the compression test didn't do it exactly right because for some reason I got 145 in one cylinder, 115 in two, and 120 in another. Other than such low numbers the car itself runs fine, but i haven't driven it since. I was thinkin should i just rebuild this motor if the compression truely is that low or just go ahead and do a 6bolt swap. The car had 140,000 miles on the motor and no crankwalk.

You can add a capful of oil to each cylinder and retest. If your numbers get better, it's just your rings that are crapping out. With 140k on the clock, I'd expect that to be the case.

I don't recall the service limits on the 2g's, but those numbers have to be close. You could just drive it until the compression gets even worse. Start building your 6bolt on the side, and when this thing finally dies, just drop her in!
