So, as I am crawling all over my '01 F250 7.3, noticed a lot of oily residue collecting around the passenger side intercooler hose and side of radiator.
Afraid to ask but what the heck, any thoughts on why?

Thanks as always.
Tom.

 

It is completely normal. The Crank Case Vent (CCV) vents into the intake and it then coats your intercooler boots in oil inside and out.

You can re-route the hose to prevent what you saw there from happening again. It isn't as complicated as this write-up makes it sound due to the fact that he is adding an optional part (the filter)
Welcome to guzzle's CCV mod web page

You can run the hose directly to the atmosphere if you so desire. That's how I have mine run.

The gist if the mod is just putting a 4" piece of pipe in where the factory CCV inlet was, flipping the direction of the doghouse, and running a hose over the master cylinder to the atmosphere.

 

Thanks rocket, yes it does coat the inside of the intake tubes. Plus, I hadn't gotten around to the "what is the ccv mod" yet, now I know. Sooo many things to learn!

If you ever need a write-up on some basic modifications or maintenance items go to www.guzzle7pt3.com and you will find step by step instructions on how to do it.

Never be afraid to ask a question.

 

Yes I know. This forum has been a god send and a pain, only because of all the mods and fixes and etc., kind of overwhelming being new to diesels. Being a factory trained tech (Honda), and working on those for 20+ years, I know enough to want to take care of everything, which is why my turbo is on the bench as I fix exhaust leaks around the dreaded up pipes.
Guzzle and Riff Raff seem to have most issues covered.

 

Looks like you've already found the 2 of the best resources we have to offer then.
