No doubt about it you are dumping oil out the slobber tube. There are two things you need to do. First verify that you are using the correct amount of oil. Cat decreased the amount of oil to 19 quarts on the C7 and your manual will be wrong. There are several home remedies for re routing the slobber tube or catching the oil in a container but make sure you do not cause back pressure in the slobber tube or put a low spot in the extension that would allow oil to collect and create back pressure. After you solve this problem then you need to clean your radiator/CAC as the oil spray from the slobber tube along with road dirt will plug up the radiator /CAC and cause overheating problems. There are good explanations for all of this if you go to the Cat RV Club site Tech Tidbits

Hey chuck, thank you. I am new at this diesel thing. Appreciate the reply.

Your welcom PONCHO. I had the same problem and after attaching a catch bottle all the oil spitting stopped. Good Luck, you will be very happy that you have a diesel.

Actually two different things will cause your white toad to become spotted. Slopper tube is the first. (do what all the others say, extend it, re route it or put a catch container on it).
The other thing is to have TOO much oil in the system. I never had the problem (20,000 miles) til the last time I changed my oil. About 1/2 QT too much and I now drag a spotted beast (toad) behing me. It is suprising how long 1/2 QT extra oil will spit out on the back of the M/H and all over the toad.

poncho ..

I have the 330 Cat in my 2004 Journey ... I watch carefully when they refill my crankcase with oil ... I am one of the "lucky" ones that have a mismarked dip stick ...

An extra quart of oil leads to lots of oily speckles on my toad ...

I also have a slobber tube catch bottle ...

After reading all the suggestions, i looked for that slobber tube and discovered that it had been smashed nearly flat and pointing to the rear, which is where all the residue was located and of course had been billowing out onto my toad and the rear of the rv. Had to hacksaw it off and stuff portion of rubber hose firmly in it and secure it with handy dandy duck tape. Ran engine and no excess anything came out. Thank you, thank you for all the resonses. Knew nothing about a slobber tube.

Modify your exhaust pipe to point down on a 45 or 90 degree angle. My gasser was staining my 5er and I cured it this way.

As mentioned some trailing is part of the diesel experience and I have found that much of it can be eliminated by driving style, especially by easing off throttle going up grades-of course this presumes that the exhaust driven supercharger is functioning normally.

Think of it as a statement to all others that YOU care more about the environment than those who are warming the planet with corn gas.

Diesel, go further-pollute less-alot less: yuk, yuk, yuk.....
