Oil in air lines?
Hello All,
I recently replaced the desiccant cartridge in my air system, it's a Haldex DA34100 system. The cartridge, which is about 10% smaller than a 1 gallon paint can, had some light brown sludge all over it. The cartridge is 5 years old, (yes, I know I was long overdue). Now usually when you mix water and oil in a mechanical environment you get that light brown sludge, so I'm figuring that the engines air pump is also pumping a small amount of engine oil through its air line and into the air dryer where it mixes with moisture the desiccant cartridge is removing. The engine is a Cummins C8.3 in a 1996 Dynasty with 58,000 miles. My question being, is it normal for the engine air pump to pump some oil out through the main air line? I don't think we talking about a lot of oil, the old cartridge had enough oil on it to be noticeable yes, but it wasn't caked on to the point where you could scoop it off with your finger. Any inputs are welcome. Thanks. - Tom
