      If smoke comes out is that excessive blow by as well?

      @@panchocapistrano6956 Sorry to revive a 1 year old post. But no, a compression tester will only tell you how much compression a cylinder is capable of producing. And sure, you can find a cylinder with low compression with a compression tester, but that will not tell you how much compression is being lost. The way to know how much is being lost is to use a cylinder leak down tester. Some compression lose is normal on all engines, but excessive can be an issue. That is why you use a leak down tester, to see if the cylinder is within specs.

    Excellent video explaining this situation!!! Had a bad blow by problem in a Saturn. Clean piston tops and rings with good soaks, and Amsoil and Royal Purple fuel System cleaners. Put on a new PCV, had valve seal blow by test too. I even put on a catch can to see the amount it was blowing by....Not opposed to fixes in a can, if they WORK ! I went ahead and tried that RESTORE additive, after all else had failed. Well the little bit it builds up on the Rings was enough to slow the blow by way way down ! I'm sure results will vary for different engines and previous care and mileage situations! There isn't much else I could do, before engine teardown. Just not worth it, on this car to me.. But it still runs well,, a little better now too.. So just a thought for anyone who has a car not worth the price of re-ringing etc.. Do everything like the fuel cleaner additives first, Clean well working PCV.. The 10 bucks was well worth it for me, at least...Great explanation on how blowby is caused and what to look for!!!👍 Thanx; Jethro
