I have an older Craftsman compressor (DeVilbliss). Seems to work well, but I noticed its starting to "seep" oil externally. It looks like maybe the base gasket needs replacing, which doesn't look too difficult to handle.
I wiped it down, and after 30 minutes of run time, the tank and motor base have an oily film... Not enough to "drip", but I imagine it will only get worse...
But since this compressor is about 30+ years old, I wonder if I should consider replacing the flapper/reed valves (and associated gaskets), just because. I'd estimate the compressor has under 100 hours on it, just a "home" compressor that I have painted a few cars, ran a DA sander and more recently spent about an hour blasting some rust.
I am looking to do some more blasting and painting.
Its a 30 gallon, portable, horizontal tank, 5 HP, 240Volt, 125 psi max pressure, 12 scfm @ 40psi and 10.0 @ 90 psi (8.3 @100)... I really like it because I can store it under my workbench when not in use. I placed the electrical outlet outside so I roll the compressor out when I need to use it, but its still convenient for me.
So should I just replace the valves (and head gaskets) while I have it apart? or since it ain't broke, just replace the lower base gasket?
Only about $33 for a gasket kit ($15+) and valve kit ($17+)… I figure I'd but the valves anyway, just to have them around (a lot of parts have been discontinued).
