I had to cut a 3 1/2 in section of 4in exhaust pipe to hook it up and it went in pretty clean. I also banged the dust out of the 6637 as well as possible. I think that'll need replacing pretty soon.
Problem: I ran 8ft of 3/4in hose (that was all I could find at Pep Boys late last night) from the doghouse down the frame rail so for now it exits on the frame rail just forward of the front fuel tank. I originally put a small piece of sponge in the end of the hose, drove a nail thru the hose and sponge to hold it, bent the nail over and put a couple turns of duct tape around the house to cover the nail. Started the beast up and it was venting through the sponge but not uniformly. It was venting at a noticeable pressure with my hand over it. Before I noticed it, the EBPV rod seal under the turbo had puked enough oil to run down into the valley and make a puddle on the floor about a foot in diameter. I figured the sponge caused crankcase pressure to increase enough to force the oil through the seal. I shut it down and removed the sponge. No more leaking. I took it on a "performance" run for about 20 min and no more leaking. Is that seal a sort of safely valve for when the CCV gets clogged? Do you guys think this seal is on its way out, even though it stopped leaking after I removed the sponge, or would this be expected? Of course I'll keep and eye on it. If it goes completely is there a fix without removing the turbo? How about if it goes out on a trip and I need a quick fix? Unplug the wire to it and JBweld it?
dont sponge the hole, dont cover it with anything, it needs to vent as much as possible, under full throttle you will notice a great deal of air coming from the vent, the cover over the valve cover does the filtering with a mesh stell wool looking filter in it, this really isnt a mod in my eyes, its a fix from fords screw up, the pcv system they added here is junk, turbo motors always have blowby and it needs do be gotton rid of, look at every medium to heavy duty truck, you will always see a hose next to the oil pan dripping some oily residue, they just dump to atmosphere. we are converting back to the old design with our ccv mod
most likey, they usually dont leak unless they are activated by the pcm, if she starts a guzzling and you dont want to pull the pedastool, then unplug it spray it down and jb weld the crap out of it
It may be even better if you put a little vacuum on the CCV. It will increase HP in gassers, don't know about diesels though.
Here's more info: Sroll down the page for a few pictures. https://www.ford-trucks.com/forums/5...ccv-flack.html
the best thing to do would be add a ccv to the right valve cover as well and plumb them both on a 45 degree angle to the exhaust so that it will pull the gasses out, look at any funny car or pro stock supercharged set-up
My pro-streeter has the set-up above. Added about 20HP, on the dyno. It would add even more with a vacuum pump. I had to use 2 CCV's because of dual exhaust (headers). I'll bet our diesels move almost as much air as some drag cars.
I did the CCV mod to my buddies 2000 PSD and got about 8 in vacuum on the exhast nipple. His intercooler and piping are bone dry plus the intake boots stay on now.
Here's how mine turned out. The black SD boot has a tiny hole on the front of it - for a vacuum gauge maybe? I just plugged it with a small screw. You can barely see it in this pic.
cuda, thats exactly what i am talking about, i think that would add potential power to our trucks as well, under full boost i would agree that we really put some air into the crankcase

Not sure what you trying to show in the pict, CCV mod? I hope that screw doesn't get pulled into the intake or fall out....ugly, very ugly when that happens. Strange place to drill a hole.
That's why I posted the pic. Maybe someone knows what the hole is for. Do the SDs use this hole for something? I don't think there's a chance the screw will get sucked in. The hole is actually more of a raised nipple - raised up about 3/8in above the tubing. Here's a better pic of it without the screw in it. It's on the top right of the pic.
im getting ready to do the ccv mod and was wondering if i could route the little 90 degree hose the comes out of the valve cover to a breather tank. because we make them at my work its a tank with a drain thing on the bottom and a k&n on top with a fitting that goes into the side.
it needs to be able to get rid of all of the pressure at once, if you trap it in a can or restrcit it with a filter you are robbing horsepower and potentially damaging your engine by increasing the pressure. blown gaskets and damaged internals could result
