I bought a new compressor. In bringing it home, I was told it would be OK to turn it on it's side. Now the one way valve, I think, has oil in it as it is leaking air at the pressure switch when I turn it to off. Is there a way to clean this valve without taking it off? In other words, can I remove the tube coming from the head and squirt some brake clean or something to melt away the oil? The reason I ask is that the valve is very hard to reach. Thanks
