hey guys and gals,

i have been tryin to figure out what the CCV mod is tried searching for it couldnt find a thread on it what is this mod and the Foil delete also. appreciate it

 

Foil delete is simply peeling the foil off the hot-side I/C tube. Makes for a cleaner looking engine bay and lets you hear the turbo a little better.

CCV Mod is for deleting the black coupler between the two halves of the tube between the air filter & turbo. It's there to suck the Crank Case Vapor out & burn it instead of releasing it directly out into the atmosphere. Those oily vapors build up after some time and are forced through the rubber boots making a mess. It can also cause the boots to pop off if they get loose. Loose + oily = POP!! LOL....

EDIT: There's more to the CCV Mod, but that's why it's done.

 

thanks for the explanation foil delete will get done this weekend i was wondering if i could remove the foil (looks like poo)...is there a thread that you know of that has a step by step for the ccv mod?

Not off the top of my head, but it's pretty easy. All you need is a length of 3/4" hose, hose coupler, and some replacement O-rings for under the "doghouse". The doghouse is what sets on the valve cover and contains a filter to help keep the oil in there. All you do is pull the intake & coupler, take off the doghouse, rotate it 180* (replacing the O-rings I'm sure are shot), hook up the new length of hose to the existing elbow using the coupler, and run it as far as you want. I have mine run all the way to the rear axle, but I'll be cutting it off at the back of the block shortly. That's the way International originally designed it.

Then you can either cap off the hole in the existing CCV coupler, or replace it with a piece of 4" OD exhaust pipe. The exhaust pipe is best if you can find one. Here's what mine looks like:


And here's a close up of the doghouse (lower right in the below pic):

 

DonnyD,

You might want to check out the post "6637 filter" and read the post by ernesteugene.
He discusses the foil delete and advises against it. Lot of guys on here have done it
but I keep thinking Ford put it there for a reason. Read his explanation.......he seems
very knowledgeable on this mod, then decide for yourself.

Good luck

 

Haha!! It spreads to another thread!!

I did it strictly for looks. I won't BS about that fact.. PM me if you need info about the foil delete.. i'll go out to the shop and see what the name of the adhesive remover was.

 

I used a varnish/paint stripper from Home Depot for the foil delete. Once you peel off the foil, the stripper is used to get all the fuzzies off the pipe.

 

Someone on this thread stated that when doing a CCV mod you need to remove the stock plastic coupler between the air filter and the turbo and presumably replace it with something else but I disagree with this approach. From the prospective of venting the crankcase there's no need whatsoever to replace the stock plastic coupler and there's a very good reason not to remove it because you might need to temporarily reverse your CCV mod in order to pass a state safety inspection. In TX for example even a simple safety inspection is supposed to include a visual confirmation that none of the emissions related components have been removed or modified.

The best way to route a CCV hose is shown in the pictures below. I don't think the right-angle bend to go up and over the master cylinder which is the approach recommended in the links you've been given is a good idea because 1) it increases the restriction to flow, 2) it allows condensed gunk to drain back into the wire mesh in the doghouse, and 3) the hose runs down the outside of the frame rail where the hose is subjected to lower temperatures.

My recommended approach is almost a straight run that keeps the hose near the engine and tranny heat and terminates at the front of the fuel tank.





The discussion below explains why the so-called foil delete mod isn't a good idea and you can read the additional details here in post #65... https://www.ford-trucks.com/forums/8...ml#post7160776
On their power pack kits for the early 99's Banks did exactly that by installing the heat shield shown below to insulate the driver's side CAC pipe so that it didn't pick up additional heat due to its close proximity to the exhaust manifold. There's a lot more clearance on the passenger side so evidently Banks didn't think a heat shield was helpful there.

Well on the 99.5 and later trucks Ford was nice enough to install a heat shield that was even better than the original Banks version, but everyone on every forum I've read seems to be very proud of their "foil delete" mod which removes this functional heat shield so that their CAC tube will look pretty or they can hear more turbo whine but removing this shield can only hurt performance not help it!
