Question and Answers


What would cause oil to blow out the intake filter of my Craftsman comp mod 919184191?


When the compressor is blowing oil, it is usually because one of the reeds on the valve plate under the head is leaking.

The reed leaks pressure back into the crankcase causing some oil to be forced past the rings and into the output air.

It also forces some air out the intake saturating the filter.

You need to remove the head of the compressor and inspect the valve plate.
