Need piston ring or not, and difficulty to replace

I have an older Montgomery wards air compressor that is a small compressor, and on the compressor on the top of the cylinder housing where there is a filter, it seems to push and pull air. It does build up pressure but seems to leak air and was wondering if the rings on the piston need to be replaced, and if yes how difficult of a project is it?

piston ring ?

Perhaps, but your description sounds more like a busted valve.

Either way, remove the head, pay attention to how it is put together.

If it's a ring problem, you may have a hard time finding a replacement. If it's a valve, you may be able to fabricate one.

If you need more help, try to give us a model or at least some pix of the disassembled parts.

You'll need to start a new page to post pix.
