Does anyone no if it is possible to still have a blow by even if the compression test was good?

Thanks

perform a leak down test if you want to be extra sure

Are you talking about the piston rings though? The way to test those is normally to put a small amount of oil into the cylinder being tested and perform the compression test again

Have you got any oil around any of the breather pipes? Sounds like you mite have a blocked PCV.
