2015 F-250 CC 4X4 PSD 113,300 miles

I understand the mechanics that cause this, but I am wondering why it is suddenly A LOT worse. I have a ton of oil in my cold side pipe. Enough to cause some drips and to mist a little spray on the inside of the hood. A few years ago, Ford replaced the CCV box with the newer, non-serviceable, non filter box. I don't see any blow-by, and there are no other oil leaks indicating crank case pressure is building up. The pic of the pipe was taken today, after being wiped clean about a week ago. I also have some that is misting out past the boots. Any ideas?

 

Looks like the sensor has a seal issue.

 

You have a "boost leak", the oil is coming from either the CCV, or turbo seals most likely the CCV as there is not much you can do about oil in the intake with a CCV system, you can make it better several ways, but it will always be there. Fix the boost leak and you'll be good most likely.
Looks like several wraps of teflon tape and 5 minutes should do the trick on the sensor threads.

 

I agree with that, but doesn't explain why i now have a a lot of oily residue around the rubber boots, and coating the side of the intercooler and the throttle body on the other end.

 

I will have to try a new O ring, as the sensor in the CAC pipe is a 1/2 turn twist in to lock.

 

replace the boots, they get stiff and dry rotted over time.

 

That is a Rudy's lit, so I'll see if I can order them.

So, what I am hearing is that amount of oil at the boots, and the side of the intercooler coated in oil, is normal for a stock truck? Seems like a lot to me, especially since it started to get bad about 8k miles ago.

Thanks for everyone's replies.

 

Yeah, I have a Rudy's cold pipe as well and this has happened to mine as well... at one point, I'm going to go to a Pusher Intakes cold pipe...

@speakerfritz how's your IAT sensor bung there? Any leaks like that at all?

 

did you recently try a new brand of oil…some oils foam more than others.assuming your not over filled.

 

No, not over filled and same brand/weight I have used since pretty much new.

 

Did you change to an engine oil with more vaporization properties, NOACK test results showing higher loss of oil with exposure to heat over time? Or has the brand of oil you've been using changed their formulation without announcing it? This is not rare, a motor oil company changing something in the formulation. Slim chance this is the cause of your increased oil in the intake tract, but a possibility.

Have you been driving with higher loads such as heavy towing? Can cause more blowby, therefore more crankcase vapors that end up in your intake via CCV.
