CCV question
I installed a CCV reroute kit (POS IMO)
years ago. It is a homemade jobber and at the time it seemed like a good idea. The kit was nothing but a 4" PVC pipe with two caps and a filtering media of some type inside, two barbed ends and a brass drain petcock at the bottom which I empty.
I recently changed out all of my CAC boots and still find oil in the HOT side tubes and decided to just vent it to the atmosphere. I plan to route it to the back of the truck (or close) and just let it vent there as Cummins and prety much all OTR trucks do.
Does anyone have any reasons why I should not do it this way?
Any ill effects to my truck etc?
Thanks
Joe

First I'll say that I am no expert on this but have been doing a ton of research on the ccv topic. Plan on building my own system because I can justify the cost of the systems you can buy.
I have read that the system needs the vacuum created when it is hooked into the intake to completely vent the crankcase. Again, don't know for sure but this is what I have read.
Since you already have the plumbing done, find a Mann + Hummel Provent 200 and replace your 4" pvc set up. Last time I searched, one could be found for around $148.
Also, make sure your plumbing to the filter does not have any low loops creating a "trap" for the oil to condense and block flow. Run your lines with a gradual ride from the valve cover and then a drop to the filter. Oil mist will then either condense and run back to the valve cover or condense and run down hill to your filter.

Joe,
I think it is fine - seems like a lot of the guys do it this way. I used the Racor filter because I did not want to get oil spots on my driveway. Plumbing it is a bit of a PITA, esp. finding appropriate hose and adapters. I have some pics in an album if you change your mind. I spent about $300 in parts from an Ebay supplier.
Make sure you have a good plug on your intake so no dirt gets in.

I also remember that.....but I also remember there is a chance of it blowing back into the CC and pressurizing it....is that possible?

For just a touch over $300 you can get the BD CCV. Yea, a little costly but a perfect fit and finish.

I think I might be done with the CCV into a cannister alltogether. I am wondering if anyone knows it a bung is welded onto the exhaust and the CCV routed to it, if that will suffice yet not damage my motor by pressurizing the CC

Rob.D,
BD uses the Mann+Hummel Provent 200 with their own sticker on it. You can find one for $148. I can't justify the cost difference for a bunch of 1" id hose.
Joe blow,
I would put the bung in on an angle (maybe use a threaded coupler for the extra length) pointed toward the rear of the truck, behind the muffler. I think you should be safe behind the muffler since there really is no restriction behind the muffler to the rear of the tail pipe.

00buck75,
I had my doubts about these types of setups in regards to their effectiveness. I am looking of ridding my intake completeley of oil residue and just have a bad feeling about routing a bung toward the exhaust......
Do you run this Mann+Hummel filter?
Does it remove ALL of the oil returning only CLEAN CCV air?
How often does the filter need to be changed?
Thanks for the help

Joe Blow,
No I currently do not run any ccv set-up.
I have just been doing a ton of research on the subject trying to figure out what filter I want to go with. Plus, I have a ton of other things to do before I have money for the ccv.
I wouldn't run it in the exhaust either.

Thats correct. Was actually just watching an episode of Trucks! on Spike, and they welded a bung (angled toward the rear of the truck) to tie it to. The angle is to maintain a bit of suction, the same thin it was doing going into your intake.
