I have bubbles coming out from the bottom of the intake air valve body. Can I use silicone/ gasket maker, or should there be a gasket?

Is that the hydraulic oil pickup at the very bottom

when you use the foor air pump for over one year, and there is no filter and dryer on your compressor. the piston will be possible to stuck with dust. you need to disassemble and clean all the pistons. then it will back to work. No need buy new one, save your money.
