Homemade CCV questions
I've decided to re-route my CCV back to the intake. Frankly I'm just tired of the smell when I'm near the back of my truck.
The only issue I'm running into right now is what to use for a filter setup. I really don't feel like building a PVC canister and using steel wool for filters. So, does anyone have a suggestion for building your own CCV catch can/filter with parts that can be picked up locally?
Just trying to get some ideas together.

LOL... I thought about it too. My piece of heater hose is getting spongy after nearly three years in place. But I think if I were to do it, I'd use a can with the vent connected to the side, and the line going to the intake from the top. I would leave the dog house reversed, and just run some hose to it. I would use a piece of PVC if it were me, just because it would be easy to plumb into. It can be painted, and screw caps used to you can see if any oil has been collected.
In fact, it might be my next project. Thanks for bringing it up...

PVC will be the cheapest and easiest material to work with, in my opinion.
I, too, have been considering taking this approach as well, but am currently convinced that I will be using the PVC and stainless steel scouring pad approach (plain stainless ribbon material... NOT SOS type of a pad) ... if/when I make the change.

I wouldn't even waste my time with extra steel wool in the can. I'd just feed it low and let gravity handle any liquid. With a tall enough piece of pipe with the feed to the intake on top, there shouldn't be any liquid getting to the turbo. I'm thinking two tees in a length of pipe for the lines, and caps on top & bottom for draining/inspection.

My advice is to "hold your breath" or "stay upwind" and leave your CCV routed to the atmosphere with the shortest length of 3/4" diameter hose that gives a convenient run and exit point so the oil fumes don't coat the underside of the truck. In order to avoid "excessive" crankcase pressure or vacuum a CCV that's returned to the intake must have a well designed "regulator" meaning one that's matched to the "filter element" which traps most of the oil vapor so that it doesn't foul the intake system.
The two pictures below illustrate the considerations involved in such a design and even with their competent engineering staff Racor didn't get it done correctly in their initial effort because I had an early version of their 7.3L CCV kit and the regulator warning "pop up" button would stick and not alert the driver that the CCV filter was clogged and needed to me changed! There were several reports of dip sticks being blown out with those early versions.

I also need to do the CCV mod, have the hose and clamps from Clay but never got time to install. I would talk with Ponyboychris, he has built 2 or 3 CCV traps and has a good design from the looks.
Speaking of which, Chris, wheres mine?

Dude, I'm sorry. Been a hectic last 6 weeks. I have all the pieces in the garage. I can build it this weekend - it's a nice cold weather project like today.

Will do, but its probably going to be around the 23rd or 24th. I am going up to Buena Vista Thurs-Sun next week. Pulling a trailer full of sound gear and other stuff. This will be my first time pulling thought the mountains.

cat's version here at the shop is a pretty nice setup. I have been thinking about calling the local dealer to see what one would cost.
IIRC, it has a replaceable filter element, an inlet, and outlet and an oil drain tube that could be vented or stuck back into the pan, etc.
