Ok I took my Filter out today for a cleaning and decided to go a little further and check the turbo out. Took all the intake pieces out when I noticed a sticky thick black oil on the inside of the black piece right before the intake to the turbo. I just cleaned it all out with parts cleaner. :dunno:

My question is what is it and how did it get there? Anyone else have this problem? Thanks

crank case oil mist. It goes away if you do the ccv mod. google or search it and you'll learn. fwiw, I've had two well respected and knowledable techs tell me the ccv isn't necessary.

Is the ccv mod really worth it then? What are the pros. and cons. of this mod?

Does the mist really hurt anything?

I think some people attribute it to aiding in their cac tube being blown off

Burning the oil will cause soot in the exhaust system (contributes to EGR fouling). There is a high ash content to the HD oils. The CJ4 formulation is designed to help reduce the problem.

it will help keep the oily residue you see on your boots from forming...
