Mike Posted December 22, 2008 Share Posted December 22, 2008 If it has a dryer/filter look to see if it is oil in it also. I go along with Terry on the subject "AIR PUMP".mike Quote Link to comment Share on other sites More sharing options...

I assume its a seal on the air pump. anybody know where would be a good place to start.Air compressor is tired. The piston rings in the compressor are probably worn and allowing oil to get pulled up into the cylinders, then the oil gets mixed with the compressed air and delivered to the air tanks.
