      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.

    This is a very good information. I have a 1988 Mazda B2200 CabPlus SE5 and recently rebuilt the engine. What I noticed is that there are some oil spill coming out of the crankcase air breather after taking to local mechanic for an oil leak from the transmission. Sad to say that my mechanic who rebuilt the engine was not available during. Upon his return, he illustrated the same way as you did and no sign of oil from the air breather, oil cap and oil dip stick. Just last night 12/10/2023, I noticed that the oil spill from the crankcase air breather is back. Sad to say again that my mechanic moved to different state and I have no one to trust. So given with your information, it appears that my truck has an accessive blowby issues. Would PCV valve would take part of it? Any help or suggestion is very well appreciated.
