Ok I have 2 questions I would like to ask: 1<SUP>st</SUP> question the soft tubes that connect the upper ridgid line to the turbo and the same soft type of tube to what looks like the inter cooler (I think) `are covered in what looks like oil blow-by or road grime I bought this truck used and it has 85,000 miles on it so is this normal and just needs cleaning or should I take it in. Question 2 I am having a cargo trailer built and I want the rims to be inter-changeable so I need to know what the hole spacing is (and if you know a company that makes either an axel or a set of hubs)
It is not normal for there to be oil residue on your tubes. I had the same problem with my 6.0. The dealership in Fairbanks said it was normal and kept replacing the tubes. They are full of it. There should never be any oil going through the air tubes. I had to move to Utah for a few years and took it to a dealership in Ogden. There is an oil seal in the turbo that is leaking. I had it fixed around 80,000 miles. I now have 95,000 on it. No more oil leaks. Let me know if you have any more questions.
Actually, unless you've rerouted your crank case ventilation to atmosphere, it's very common for there to be oil inside your Cold Air Charge tubes. I'm not discounting a possible turbo seal leak. However, the 6.0 dumps its crank case vapors into the intake tube just prior to the turbo. These vapors have oil mist that will coat the inside of the tubes. The only way to prevent this from happening is to reroute your crank case ventilation. There is a procedure in the 6.0 tech folder.
As far as your wheel question, I'll have to defer to someone else on that one.
Yes, I have Oil all over my tubes. It looks like the tube closest to the turbo is ready to pop off. I too thought the Oil was coming from the breather tube, but I recently changed the Air filter. I had the intake assembly off and it doesent look like the input to the turbo is full of oil. Is it possible all this oil is coming from a turbo leak? I dont understand the link. What does TSB 07-05-15 have to do with a turbo leak.
What should I say to my dealer, change my turbo, there is oil on my tubes?
