Oil and moisture in CAC pipe

Hi all. I had to change out my top alternator yesterday. What a chore that turned out to be, but that's another story.

In order to get to the alternator, I had to loosen and move the CAC Pipe out of the way (at least I'm assuming that's what it was).

When I took the pipe off, I noticed some oil and moisture in there. Is this a problem? Truck seems to be running fine, and I am not sure how one would keep out moisture if you're taking ambient air and compressing it in the turbo (assuming I understand this stuff--which is a big assumption).

Anyway, I've attached some pictures to give you an idea.



The picture above looks a little goofy because I forgot to rotate it clockwise 90*.



Thanks,
Chris

That is completely normal. It is oil from the CCV system. I recommend installing a catch can for the oil or rerouting the CCV system to the atmosphere.

This right here is a GREAT line. Don't worry, Chris. We've all been there.

Thanks.

Boy, howdy, if you don't put that CAC pipe/coupling back on correctly (there is a notch in the pipe and an "extrusion" on the rubber coupling), it'll pop off pretty easily. And when it does, you lose lots of power and blow lots of smoke... ask me how I know
