The first sign of the crankcase breather being blocked is a "POP" of air pressure when you unscrew the filler cap. Maybe the previous owner decided to drill the cap instead of replacing the filter. There are posts elsewhere on how to do replace the filter. Suggest you replace the cap with a complete one asap.
