OP
Well I finally go around to finishing the rebuild. Fired it up a little bit ago. It starts great, builds pressure great, but when I shut it off I get a good bit of blowby from the 3rd stage piston? A good steady hissing until I bleed it down.
The only thing I can figure is maybe it takes some time to "seal" the new rings / teflon to the walls?
I cleaned each cylinder with soap and water during rebuild, nothing else. The 3rd stage piston is brand new from the factory loaded directly into the cylinder with the correct tool. Just pushed it in very lightly.
As far as the pressure goes it seems to be building pressure just as it did before, so I don't think I'm getting any blowby while it's running. Any thoughts?
