Have a check valve that I think is letting air through......it is either stuck open/dirty/clogged, etc... (just got the compressor, Ingersol Rand 5 hp/60 gal..built in 1987....it had been sitting idle for 3-4 years...everything was very dirty, covered with layer(s) of what I think was dried out auto body filler dust but cleaned up very nice....) or worst case defective............want to try and clean it before spending money on a replacement..........wondering what would be the best way to try and clean it out........not sure if a grease cleaner/solvent would damage it in any way.........any tips/suggestions would be appreciated.
Thanks
