This write-up shows an easy way to mod the York compressor to keep it from pumping so much of it's crankcase oil into the air tank/ lines/ tools/ tires/ etc.
http://www.rockcrawler.com/techreports/york_mod/index.aspBe sure to read down the page, i did the 'behind the clutch' mod back in 2005 and i wish i'd seen this easy way first. To get ALL the oil out of your air lines, an oil/ water separator between the York and the air lines will remove the oil this mod doesn't. In my opinion, putting a York on your truck is a really good mod.
All those guys with the CO2 Powertank argue with me, but i never run out of air, and it doesn't cost me $25 to get it filled.
