Well I'm still saving to get a programmer and do all the deletes but I was anxious to do a mod and start adding some long term reliability to my motor so I decided to do the CCV mod. I've read several threads on it and it looked pretty easy but I never saw exactly what I was looking for so I thought I'd see what I could come up with. I wasn't crazy about the idea about running a 1" hose across the engine bay, just seemed cluttered to me. I prefer a clean factory look, something that blends in. Let me know what you think.
First, I started by removing the factory CCV to get it out of the way. To plug the hole in the intake hose I used a 1" expansion plug, I borrowed this idea from a fellow member. Here is a pic of the plug I used.
Here it is installed.
Next it was time to figure out how to route the vent hose down and out. I have seen a few pictures of guys who used 1" hose and just did a u-turn and ran it down the passenger wheel well and I liked it going out the passenger side but the hard bend often kinked the hose and I didn't want to risk not having good flow. So I decided to improvise.
I removed the hose used to evacuate under cab heat and route it into air filter housing. I plan on putting on a cold air intake when I do a programmer and exhaust so I don't plan on reusing this anyways.
Here it is to show what I'm referring to:
I decided this would work great because it already has a preformed bend in it. So I started doing some test fitting and found out it would work pretty well with the short side of the bend connecting to the outlet for the CCV and the u-turn would point the long side right down the fender well.
In order to make it fit nicely I had to cut a short section off the short side of the bend and make a notch in it like the factory hose.
Here is a couple pics to show it.
I also cut a short section off the long side of the hose that has the flared end that holds the plastic scoop. I'll reuse these pieces later.
So now I have the initial re-route of the vent hose but it needs some length added to it. To do that I just used a pvc connector used to splice hoses and I got 10 feet of 1" rubber hose from my local farm supply store and a couple hose clamps. Then I just started to rout the hose down the fender well. That was a pretty tight fit so it took a little time.
Here are the parts I had.
Once I had the hose routed I hooked up the original hose I had modified and started working it into place.
With a little pushing an pulling I got everything in place and put the hose clamp on the outlet for the CCV. Here are the finished pics.
As far as the rest of the hose, I just ran it down the fender well and then ran it down the outside of the frame rail, the 10 feet got me just shy of the back of the cab. And the flared piece of the hose I cut off, I put the plastic scoop back in it and used another pvc connector to splice it to the end of the hose so it made a nice turn down just at the back of the cab.
I will say you can smell it outside of the truck but it isn't overwhelming by any means, and you can use as much or as little hose as you want to as close or as far away from you as you want. To me it is well worth it to not have the oily air going back into the intake.
Hopefully this helps anyone considering doing this mod. Enjoy
