Ok i bought this used compressor and it airs up to 170 lbs no issue but i am feeling air out of the oli filler tube and oil in the air filter. I figure this needs rings and seals i guess. It is a 2 stage and i guess if I tear it down i should do both cylinders. ok so my questions are this, can i just rent a hone like harbor freight sells and clean up the cylinders then install new rings and seals or do i need to buy a special set of rings or do i need to hone the cylinder at all. do you guys have a manual on this compressor or pump. I think Devilbiss made it and i know its old, i think the abp-4900 is the newer version any help is appreciated!
