Ive got a slow oil leak coming from the CCV. I replaced it 4 months ago. It's after market. At the time none of the dealers had motorcraft in stock. I was going to wait about a month for the OEM. So I settled for a cheaper one. It fit good or so I thought. I replaced the orginal one after i noticed it was leaking a decent about of oil. I thought it was plugged and was putting excess back pressure on my seals. When I took it off one of the plastic joints that mounts on top of the valve cover was broken that's why it was leaking. I really hate oil leaks so Im wondering if anyone has put a CCV cover kit on it or should I just replace it with an OEM one. What does the ford enthusiast say?

 

you should replace with the latest ford ccv return to intake box

the new ccv box is a lot thinner and easier to install

the picture tells it all

 

There are a couple of threads lately talking about this, just scroll down through the threads a little. In your case, I would either swap it with one of the most current Ford OEM CCV's, or do a reroute. I myself have been debating this for the past couple of weeks and decided to take advantage of the 10% off code at SPE MOTORSPORTS (important: not SPE Labs) and opted for their CCV reroute without the internal catch can, and then I also added their external catch can. With the code this was $520, so not the least expensive option at all. In fact, this is the most expensive option I have come across...

And.... I am still not sure if I made the best decision... I really don't want to see "smoke" coming from under my truck, and while I don't think that I will care about the smell, this is also hanging on to how much smell will their actually be. I don't really want either to be a nuisance, or to draw attention... I have read so may threads lately, and watched many YT videos... it seems the amount of smoke and smell will differ from truck to truck, as well as installation to installation... so there will be no way for me to know for sure until I hook it all up. I did not add the internal catch can because I want to minimize blockages to flow/pressure, and instead opted for the external catch can. I hope that this will be sufficient in catching and the smell and minimizing vapors... I guess I will eventually see!

The only way to completely not worry about either is to keep the CCV recirculating. SPE Motorsports also have a nice looking CCV Recirculating kit, however, it lacks a "crank case depression regulator" and based on my limited, non expertise opinion, I don't like this. Had they added this to their recirculating kit, I would have 100% went with this option, and I wouldn't be second guessing my final decision while waiting for the parts to come in... If you want to keep the CCV recirculating, the newest FORD OEM CCV is the best option, however, it is not a one and done thing... depending on use and your motors health, it can deteriorate in either a short, or long amount of time. There is no good way to tell. Also, FWIW, another user here showed his new OEM CCV leaking oil soon after installing it... so... yeah...

Besides this, there is a proper way to se up a CCV reroute, otherwise, this can actually increase CC pressures, which would make things just as bad, if not worse than having a clogged OEM filter. As well, there is some discussion as to whether or not the whole intact system benefits from the negative pressure created from the turbo as to whether or not it helps remove some CC pressure (obviously with a non clogged filter). Then, there are even some that believe that removing the CCV and rerouting it to atmosphere/catch can/exhaust will actually wear out the seals in the turbo... I am no expert, so I can't say for sure... but all of these things get talked about and there seems to be very little scientific data to back up any of the claims. Just a lot of "use-based data."

Anyway, here's probably the best video on the subject that will get you going down the rabbit hole! Good luck!

 

Thanks Chadstick for the response. I think im going to just go with an OEM it's only about 130ish. I live in CA and I think that the reroute kit will fail smog in this wonderful state. My truck damn near failed last time I had it smogged... for BS a check engine light that I had already fixed and cleared. Didn't quite make the 20 cold starts and 200miles. I did hear that they may be getting rid of CARB but I wouldn't hold my breath under this phenomenal leader ship that's been plaguing us for 8ish yrs

 

Being in CA, the OEM CCV is the way to go. Too bad SPE didn't add that pressure regulator to theirs, otherwise it would be a good option.

 

How does venting to atmosphere damage turbo seals? Up until the invention of climate change that's how all engines were vented.

 

I’m the last person to say that this is true, but it has been said… most seems to stem back to Bill at Powerstroke Help. I guess the claim is that if not done right a reroute can increase CC pressures…

 

That was the only sited reference I could find that mentioned anything at all about the turbo issue. Bill was a wealth of diesel information, and the industry lost a valuable resource when he passed away, but without more corroborating testimony I wouldn't take it as gospel myself, personally. If more findings are presented subsequently that support his recorded opinion from a few years ago, then I'll consider that in any ruminations as to whether rerouting is harmful to the turbo.

 

Does this graphic include the "non filter" OEM box that was replaced on my 2015 under a previous recall?

 

I wouldn’t think it is either, and I believe that it all stems back to Bill’s content. However, I have seen it repeated in other threads here and other Ford 6.7/diesel forums, as well as in YT responses and even FB groups. Being that I plan to reroute to an external catch can myself, I hope there is no truth to it!

 

There isn't, if you watch the video he doesn't preform the same tests before and after he "fixes" it. Just more fear mongering.

 

LOL, I had this discussion before with others here ................seems they are convinced that the moist ccv gases lube the turbo and keeps the seals wet.

 

Corrected it for you Jim...

Maybe the guy with the 900k mile plus 6.7 thought the same...

 

corrected what?

 

Your comment... you said "others here" and I corrected it to "someone here."
