I would have to say if you are blowing oil out the crankcase that you have a piston or rings problem

Why won't it pump up past 40#?


If you don't have any air leaks, the cylinder head gasket is probably bad on the pump. Easy fix for less than $10. you can get the parts you need here:

Craftsman 3 gallon 1hp. Motor runs but no pressure buildup. Oil level okay and no obvious leaks.


Your motor is good and your pump is in need of being rebuilt. I would price both the rebuild and the cost of replacement all together as there are many good cheap used compressors crying for a home.

Have 12 gallon / 1HP Craftsman compressor, accidentally ran it while it was low on oil....about half way low. It shut itself off. Then, I added oil and it started up. But now it builds pressure VERY slowly...


Not the motor, but probably the compressor shot. Heat from friction (due to running without oil) probably scored the cylinder walls, which allows air to escape past the piston and rings, making the compressor VERY inefficient. Some compressors have replaceable cylinders... Not sure if the very small ones do or not.
