Who has the best CCV mod? Where did you get yours or the instructions on what to do?

 

Ford. It's there for a reason and it's not just emissions.

 

I hear that quite often "It's there for a reason"... I don't always believe that to be true. There are some aftermarket manufacturers who build superior products to OEM. But in this instance, I think I agree with you. I won't be doing any CCV mods until I can research more...

 

Looks clean! Is that the Original degas cap?

 

Really? How does the CCV, as originally designed, make the engine run better? If you have some info, I'd like to hear it.

That oil mist certainly isn't good for silicon hoses. Mfg of silicon hoses/boots even state they are not designed for use with petroleum products. That is why Ford had to change their boots with a different inner layer that resist oil.

To mod the CCV, you have two choices. The first is to vent to open air, which is what most people do. The second is to plump a catch can into the system. The catch can is supposed to 'catch' the oil keeping it out of the intake tract. With the catch can type system, the air, less the oil, still goes into the intake.

 

I've had my CCV "rerouted" for the last 70k miles (4 years) with no trouble. Back on topic, I replaced my boots with stock ones at the same time. How long should expect them to last? I tow heavy, but not in the mountains.

 

I had the updated oem boots (ones with the oil resistant inner layer) on for the approx. 110K miles. It might have been longer (120K?) but it was at least 110K. IIRC, I got those boots in 2005 (?) when they first became available. If someone remembers when the updated boots came out, that would be helpful.

I just recently went to the Riffraff boots while going through the truck doing all the 150K mile services. Lower pricing is why I went Riffraff instead of oem again.

 

Thanks for the info, I'm doing google searches and coming up with a lot of cons, I guess that's for the catch can system. Actually I need to do a deeper search, because a lot of it deals with the 7.3L. I'd like to switch to Riff Raff boots and CCV mod if I can get more info.

 

Never said it ran better, the question was what is the best ccv mod. Research crankcase venting turbo charged or super charged engines for what happens when you vent to atmosphere. With the air/oil separator you have to plumb a return back to the sump or dump it when it is full.

 

Third choice is an exhaust evac system. Which would actually be the best as it would scavenge the crankcase the best and no mess.

To which you responded, "Ford. It's there for a reason and it's not just for emissions."

So what's the reason? Seriously, I'd like to know.

I'm not a engineer but it seems to me the way the fitting is oriented the intake actually is pressurizing the crankcase. I was under the impression that a slight negative pressure would be better for boosted applications.

I also know that, in theory, a lot of blowby would be pushing oil out. My line doesn't appear to drip. Been parking my truck in the same spot for 9 years. I do know that it 'breathes' as I can smell the oil if I lean down by the exit.

 

Okay replaced the boots but I'm hearing the same noise when towing under load. Here is a video of the sound. It starts around second 29 sounds kind of like a tea kettle. I'm thinking bad degas cap. http://s1313.photobucket.com/user/ca...ea2f0.mp4.html

I've done the road draft tube CCV mod on most of my vehicles. The ones you'll notice the most difference is on turbocharged vehicles. I had a small oil leak on one of my Audi's that I wasn't going to get to until I pulled the motor for bigger turbos. Went and did the road draf tube setup for the CCV and the oil leak nearly stopped. Also, when I pulled the lower hoses from my intercoolers they had almost no oil in them, just a very light film. With the factory system in place the bottom of the intercooler would be full up to the hose outlet.
