Head Gasket Kit B5900 #05BF5A

Four gaskets needed for valve plate and head gaskets. 

Note: Two-piece valve plate style only. No returns or refunds.

If the compressor pump doesn't seem to pressurize as quickly as it should or is leaking in between the head, valve plate, cylinder, or crankcase while running, there's a good chance you need to install new gaskets. You can spray soapy water on the pump while it's running to inspect if there are any bubbles forming, which would indicate a leak.
