I will just ask the stupid question, are you sure it is engine oil and not transmission oil. It depends on how much highway driving because of the way the wind swirls under there.ĭuring the second gen Dodge era they installed a catch can but it would get over filled and the wind would pull it forward into the back of the radiator where it would attract dirt until it clogged. I've had two of them and they both did it. "Without challenge, adventure is impossible". A diesel of any brand would have to be leaking several quarts/gallons between changes, before I would spend the big bucks to stop the leak.Ģ016 Fleetwood Flair 31 B Class A w/bunks Some of the Jimmy diesel ranch equipment I grew up with was the worst with the pressurized crankcases for leaking oil. I have always found diesels, to be like the couple of Harleys I have owned, if not leaking then something is wrong. So it was still weeping when I traded it for my current Chevy, as I wanted to go to a one ton with DRW. I did all my own oil chages so kept an eye on it but didn't see it change over time. It stated the weep/drip, at about 65,000 miles and I ran the truck till it had 144,000 miles on it. Not really a drip and I never had to add any oil to the engine doing changes at 5,000 miles or transmission at 25,000 mile changes. It was coming down between the engine and the automatic transmission front housing. My last truck, a 2002 Dodge/Cummins, started, what I would call weeping at the rear of the engine. Is the engine using any oil between changes? If not, then I wouldn't be too concerned with it. Even the coolant line clamp on back right side of the engine had ppl thinking they had a tranny leak. I don't see how the draft tube could blow back up that direction.Īgree with ScottY.a little excessive blowby and depending on tube routing oil is gonna blow everywhere or collect. It could be trans oil but it would and should be continuous. Odd? The draft tube never gave me problems before.

You could do what I did and extend the draft tube down another 8". Not the best of designs but it doesn't hurt anything, just looks bad. It looks really suspicious and I even took my truck back for this when it was only a few weeks old but it's not an issue.

It hits it right where there's an opening for a leaking rear main seal to drain if it was indeed leaking. More likely it's coming from the draft tube and blowing back towards the trans bell housing. There is a gasket where the shifter enters the trans that it could leak.
#2007 DODGE 5.9 CUMMINS REAR MAIN SEAL MANUAL#
I hang out on a couple of DC forums and have never heard of this - maybe its a half ton thing? At any rate, the Cummins G56 manual trans isn't "notorious" for it. I think it has some type of plastic bushing of some sort that wears out.

Is it a manual transmission? If so they are notorious for the top of the trans for leaking gear lube. So is there anything else that it could have been? Not from the vent tube, I checked on that.Ģ013 3500 Cummins 6.7 Quadcab 4x4 3.73 68FE Trans, 2007 HitchHiker Discover America 329 RSB I thought that if your rear main seal is out, it will always leak. Now I have been on some trips non towing, and local use, and I see no more oil on the ground at all. I took it to a mechanic for an oil change and he said that that is where the oil was coming from. I came back from a trip pulling the trailer only to find oil on the ground over a few days. My 2005 Dodge Cummins started leaking oil from what appeared to be a rear main seal.
