The day i bought the compressor i had the owner hook it up and run it for a pretty long time and it worked beautifully.
When we took it out of the truck it had been laying down (for over a day) and alot of oil started flowing out of the air filter. It soon stopped. Today i cleaned it up well and blew the motor etc clean. Took the air cleaner of it and cleaned it up really well (until i can get another one), went to Lowes got some synthetic oil and filled the resivoir up.
I moved it into place and plugged it back in started running well but in a about 5min or less starting making a intermittent low popping sound - it was comming from the relief valve on top of the head (one that the aircleaner is attached to). I unplugged it, took the air cleaner out and blew it out with air really well - getting out some sludge material but not alot and cleaned that hole in back of the air filter best i could. Hooked it back up and same problem. So i shut it off and thought i would ask for some help to see if anyone knows what i should do ? or was it caused by the oil flooding those areas when it was laying down ?
Any advice would be great as i dont know to much about compressors....
