I am doing work to my air system. (See thread "My Truck...Decisions") Im doing: bellowed up pipes, turbo rebuild with compressor wheel, intercooler boots, plenum reinforcements and such. I am going to clean everything good but I really don't want to get everything recoated in oil.
I dont currently have welding capabilities so tie-ing into the exhaust is not an option. Do I do the guzzel route with running it to the back with a catch or the NC Hornet style and filter it and return it to the intake. I have already spent way more than I should have on the other parts so I will be building the catch can or the filter myself. Has anyone still had oil getting into system after filter. Has anyone actually had cc pressure problems after Guzzels style mod.
Here in PA there is no emissions testing to deal with on diesels (as long as it doesn't change) If it does change i have bigger problms lol. No muffler or cat on my truck. EGR delete on my TDI jetta lol.
Mine is a hose routed up over the brake master cylinder then down along the frame rail. I went uphill first a little bit to help some of the oil end up back in the engine. I'm not sure if that helps or not but it has been this way for several years. I moved this setup from the old truck along with the engine when I swapped the engine into the new truck. you can kinda see it in this picture.
There is a lot of information out there concerning the pros and cons of a CCV re-route. After reading as much as I could, figuring up what I would need in parts and labor, I decided against it.
In my opinion, the CCV does in fact put oil into the CAC system and turbo. Although, trucks like ours have been running for nearly 2 decades without issues other than dirty turbo or boots. I have done a lot of modifications to my truck, but I try to keep them on the useful side (headlights, radio), or modifications that will benefit the truck in a mechanical nature when traveling (traction bars, SB clutch).
The CCV re-route, I did not place in this category based on my own research and reading the experiences of others. Your thoughts and opinions may be different and I wish you the best of luck with making your decision.
If you decide to press on with the CCV re-route, perhaps try to mimic some of the catch systems that have been designed and are selling for much more than they should be. I seem to remember a nice one used by the VW crowd (you might be familiar with it) that was reliable and easy to clean.
Guess I'll go from just subscribed on this to commenting now. I'm almost in the same camp as Sous on this one. I've looked into the catch can route instead of the tube out the back of the truck tho. Mostly because I don't like the idea of oil vapors collecting and cooling inside the intercooler and building up sludge inside the cooling passages and reducing its cooling efficiency. Plus a catch can returning to the intake tube would offer some form of a "vacuum" draw on the ccv and not lead to the underside of the truck being stinky when exiting the truck like the tube does. Once I find a catch can big enough and not insanely priced and time and $ to spare I'll look into actually doing it. Untill then the cost/wrench time outweighs the possible benifits
I tried routing the ccv down the frame but didn't like the fumes and smoke so I returned it to the intake. I don't think a little oil hurts anything with a diesel.

I agree 100% of that, plus I have to deal with emissions so I modified my CCV mod to deal with both issues.
So my plan is to run the hose to the back. At least for now. I will t in a oil catch can when the hose reaches the bottom of the truck so I don't have to worry as much about low spots the rest of the length of it. What did you guys use to plug the opening in the intake? i was looking at a rubber plug. Does anyone know the inside diameter of that bung?
sub'd a while ago.....did the research at least a decade ago. life happened, project and all the parts got mothballed while raising foster & step kiddos...... well, found the stuff in a couple boxes. started preping the mod over the last month.....
Saw the research done in US.gov fleets and municiple fleets and canadian stuff too. discovered the patent war too.... made my own amalgumned design from both the waring parities designs.....
may take a month or 3 to finally get this done.. but, rest assured. pics will occur.....
Well since it is resurrected I will tell my results. I rebuilt my turbo while I did the mod. When I got back on the road my truck was basically an oil fogger. All post combustion. I assumed there was a problem with the the turbo rebuild so I was speaking with my mechanic to have him take care of it. He suggested disconecting the mod. I did and all the oil stopped. I do not recommend do the CCV mod at all.
