Hi everybody. I have a Central Pneumatic 21 gallon air compressor. I first bought it last year. I later exchanged it for a different one because the cylinder head was turned at a weird angle. The air filter was agaisnt the plastic fan shroud.
Today, I noticed that the new one I currently have takes longer for it to build pressure. I noticed that air was escaping through the vent on the oil fill cap and that there were tiny bubbles in the crankcase. I also hear a rattle. It sounds like rod knock. I think it has alot of blow-by. This was like this since the day I exchanged it. It has never been run low on oil. I only use SAE 30 air compressor oil.
I'm probably just going to exchange it again. I have the 2 year extended warrenty on it. It came in handy once before.
