Rob Posted January 10, 2012 Share Posted January 10, 2012 You probably have residual oil in the plumbing from the compressor passing oil. This will take a while to work out by itself. I like to take the compressor discharge line loose and every place else easy to get to and then using a compressed air engine washing gun with a suction hose in a pail of alcohol, blow the lines clean. When finished, allow the alcohol to dry for about an hour before reconnecting the fittings. The inject alcohol into the system when it is running to pass any effluent into the air tanks to drain out. It will take a while to get all the oil out depending on how much was there but it will eventually clean up.Rob 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

MidniteMechanic Posted January 10, 2012 Share Posted January 10, 2012 Sounds like the air dryer needs serviced also. Quote Link to comment https://www.bigmacktrucks.com/topic/22573-oil-in-the-air-system/#findComment-97426 Share on other sites More sharing options...

Higgy Posted January 10, 2012 Share Posted January 10, 2012 ..and don't forget to drain your tanks daily. I know most people almost never do this. I'm sure it helps after a compressor failure.

Rob Posted January 10, 2012 Share Posted January 10, 2012 Can't believe I forgot to mention the air dryer cartridge. I would also get a rebuild kit for the discharge valve while it is apart, and check the heater for the air dryer if equipt with such.

billythekid Posted January 10, 2012 Author Share Posted January 10, 2012 I will do so get a new filter for the air dryer that and do what you said rob Quote Link to comment https://www.bigmacktrucks.com/topic/22573-oil-in-the-air-system/#findComment-97435 Share on other sites More sharing options...
Rob Posted January 10, 2012 Share Posted January 10, 2012 I will do so get a new filter for the air dryer that and do what you said robBe sure to wipe out the inside of the air dryer housing too. To be safe, I'd prolly get two filter cartriges and change the element again in a month or so as it could continue to trap foreign matter as the system completes it cleanup.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Swishy Posted January 10, 2012 Share Posted January 10, 2012 my 2 cents worth from the udder side of the worldif the compressor air intake is hookd up 2 the engine air cleanern when the Govonor cuts out @ 120psi the suction from the mighty marvelous mack motor can suk oil up past the compressor piston ringsn then gets blown south to the wet tankit happens more when the air cleaner element is plugged a littleifn U get my drifta little oil thru the air system hurts nunn tiz better than haveing water or condensation as this causes rust thru out the air systemcya§wishy Quote Link to comment https://www.bigmacktrucks.com/topic/22573-oil-in-the-air-system/#findComment-97446 Share on other sites More sharing options...
billythekid Posted January 10, 2012 Author Share Posted January 10, 2012 Ok so you think if i put the old filter element housing back on the one that is on the commpresior it's self it will help if because i changed it when i put the new commpresior in i made a line and put it on the air cleaner pipe?

umodelnut Posted January 10, 2012 Share Posted January 10, 2012 Before we put my u model away we drained the tanks and oil came out when we pulled the plug on the air tank. It was very little oil though so should I worry about it?
