Those that are deleted (or not) have you taken off the CCV? I have only seen a couple kits so they are not "as popular" as exhaust, EGR deletes, etc. Any thoughts on them? Seems if you are already deleting, doing this would just help keep more crap from being put back in, what your motor is trying to get rid of.

 

The funny thing is, crankcase vapors and a little light oil are not the problem some people would have you believe it is. Its just not. We all can agree that emissions controls have made all engines more complex and present problems however I am of the opinion that *******izing your truck at this point opens you up to a whole new set of problems. I see it all the time. IMHO

 

Have to do something with the pressure from the crankcase.


I don't think it to be quite the problem as on previous motors.

 

i did it with a kit from MPD. now theres hardly any oil build up in my CAI pipe. before it was covered in oil.

 

Senix, so you think deleting the CCV messes with the pressure in the crankcase? Is this good or bad? I was thinking the less stuff being put back into the motor, the better for longevity. I just recently deleted so now I am looking at everything else I may be able to do, that I never saw before. It just seems that if this was as important as egr, that "everyone" would do this also, and more companies would make the kits.

 

all aftermarket turbos require a ccv delete unless its a 15 retrofit

 

My concern is the build up of pressure. that pressure needs to go somewhere. So if you do a catch can or filter in thru a filter then consider the displacement and HP of the motor so you get the right system.

 

Is this because of space, or they know it could potentially be harmful to their product? Seems like maybe they know a little more than me. I would just love this truck to last a long time. I was amazed how much crud had built up in the EGR ports when I deleted, and that was only after 19k miles.

 

Best way to do it in my opinion is to Venturi it into the exhaust.

 

I've always been told it is better to have the crank case under a little vacuum if possible. Supposed to help keep down on oil consumption.

 

i vent mine to atmosphere

they do the ccv delete simply since the crank case is recirculated for emissions reasons. aftermarket turbos don't use emissions equipment in most cases. some part of it may be due to making room for piping or a larger turbo

 

I have heard of this being done on a 7.3. I was going to do it to my old 7.3 but I could not find an old style of PCV that was threaded or weldable.

 

Do you see any oil consumption issues? Got any pics?

 

ive done it with my 6.0, but i just ran a line down the frame rail to the back of the truck. Smells kinda funky but now the boots are clean, and being able to see a like grey haze i know the trucks running well. Once i get my exhaust done on it, im gonna have my muffler shop tap into the exhaust pipe before the muffler.

Honestly though, i too have heard that bypassing on these 6.7's is bad for the pressure loss. Has this been verified?

 

over time i loose oil but only a few table spoons over the course of an oil change. i used to use a catch can thats where I'm getting the figure from but found it not necessary since I'm not putting it back into the intake.

anyone thinking of doing it should pull the tube coming from the stock vent filter and see how much oil is in it.
