If you're getting the impression that compression checks are hard to quantify, you're on the right track. If you are serious about selling the car and want people to know, without a doubt, that your engine is strong, then get a leakdown test. This test is similar but the shop will supply compressed air at a known pressure -- and it's this controlled environment that removes so much of the uncertainty. It might cost you $75, but it will ward off lowballers who ask for $5k off your price due to a tired engine.
BTW, your numbers look decent. It's rather unlikely that a tired engine would have such consistent numbers.Last edited by Thor; 10-31-2008, 03:19 AM.1987 Euro M3, Jet Black

My elevation is about 4400 ft. the tube length used was about 19-20 inches long. I was trying to get this done before the auction ended so it might put aside any ones doubts. If it doesnt sell during the auction, I will take it to the BMW dealership and have a leakdown done.
Thanks for the help and info.
next Bid Meets Reserve! this Car Will Sell!
