My pump has pressure in the crankcase.

I have a coleman powermate 5hp 80 gallon compressor. The pump will slowly build pressure, but I also have pressure building in the crankcase. Is this a valve problem? or possibly a ring problem? There is a small amount of air coming out of the vent hole in the oil filler plug. I noticed this along with a blown head gasket. So I replaced the head gaskets. I still have pressure in the crankcase though. When I had the head off I did not see any scoring of the cylinder walls. Everything looked to be in good condition. Please help, as a new pump is alittle more than I would like to spend right now!
