My Dad has a 1999 model 2500 with the Cummins 24 valve under the hood. He is a big fan of the truck and the engine (transmission is another story) but the other night he noticed quite a bit of oil around the blow by tube and all over the steering box and everything else. At first we thought it was something else but then I noticed how wet is was inside the breather tube. He is starting to worry about this and wants to know if there is anything that we can do to fix this. He does not take it offroad or anything so I cant see where that could be an issue. The only thing he has done to it is put a K&N air filter in it and he put a Superchips programmer in it as well. It stays on performance tow all the time. Like I said the truck has always been taken care of so I just dont understand it. He cant stand a leaker and if something is about to go south on it or in it it would be nice to have a heads up!!If anyone can give me any info on this matter it would be great. I am a huge fan of this site and everyone is always helpful. Thanks again to everyone.
