I bought my compressor new in '83 but I only ran the bodyshop for two years until I moved due to a depressed economy . The point is my compressor crankcase is not vented either. It is a four cylinder single stage 17 cfm @ 100 psi. Never had a water problem in the crankcase, but have had the pump literally smoking hot when I've been doing sandblasting. I think I may have taken the temper out of the rings . Time for a rebuild .
