After a little research I figured out that a hose that's been pushing out what I thought was exhaust fumes is actually Blow by fumes being dumped under the cab. After a little research I see that all diesels have blow by and after a few videos I've determined that mine is not excessive. (Constant flow but no pressure behind it and won't pop off the upside down oil cap).

My truck has an upgraded or maybe just replacement turbo with a front-mounted intercooler from a 2011 Super Duty and and custom intake intercooler and exhaust piping. It looks like these gases are usually rerouted back into the intake system? If this game is a little more performance or whatever I don't really care. The truck has plenty of power and aftermarket parts as is. I'd assume not smell those gases or put them back into the environment. I read a lot of people have a lot of oil coming out of their tube when this mod is done and possibly that's an old retired motor. I drive the truck every other day and I've yet to have a a drip in my driveway from that tube so I'm not getting a bunch of oil which I guess is good.

Now to the question. Without a doubt if all else fails I'll at least run the tube all the way out the back of the truck so hopefully I don't smell it as bad. I would like to connect it back up to the intake system even if I lose a few horsepower or whatever the effects are. If I weld a spigot on the intake system do I do that before or after the intercooler? Are there any sensors or anything else I need to do other than route the hose into their? I assume from keeping what little oil bypasses out of the intake system I could put in an inline canister that the oil could drip down to the bottom of and the gases pass through? Anything else I'm missing?

Here's a good thread to read. If you search for CCV mod you can read forever on this one.

You hit one of the main points about keeping the oil out of the intercooler. Can't vent it into pressure. You're well on your way.

 

I would re route it back to stock, of all the IC i have removed from the 7.3 trucks at work (one with severe blow by and also my truck with bad blow by) none had more than ounce or two of oil in them when drain for a day or so.
i also did a DIY ccv mod, and yes I collected IIRC a cup full of oil in a very short time, went back to stock because I had to drain it at least 3 times a week ( and we're talking a quarts worth of oil on those 3 times) when I rebuild my new engine I took off my IC thinking it would be full as much oil it was going thru and the most that came out was no more than two ounces.
Hope this helps you decide.

 

Thanks for the reply guys. It looks like I might want to take it back to stock but I would also like to read up on that thread, unfortunately the link isn't working. If you have time please resend the fix the link or I can try to search for a little later. Thanks though either way.

Did the changes to the CCV actually increase oil consumption? I could easily believe it. I bet Ford builds a better crankcase vent than almost all of the modified CCVs.

This modification is one I won't be considering for my own truck as it has no intercooler.

 

On my truck the crankcase valve has not been turned around backwards. It's in the stock configuration and has a 90 coming out of the valve and a hose going down dumping behind the engine block. There's always a small drip of oil hanging on to the end of the hose but I've had my truck for a month and I don't have a single oil drip in my driveway. I have an intercooler mod on my 1996, but I see no reason not to Route this back up to the stock configuration. The motor is fresh and rebuilt in the last year so obviously I'm not getting the oil that a lot of the guys with more miles are getting. I don't want to smell it and I'm wondering if fuel Vapors going back into the combustion process might grant me better mileage instead of worse. Seems a lot of those vapors are unburnt fuel. I don't see how people aren't losing mileage or I can't gain mileage by re-burning that otherwise wasted fuel. With my Boost and intercooler I'm guessing the fuel Vapors more than offset the amount of CO2/useless Vapors when mixed with fresh air Andre combusted. Of course I have no information other than videos and research and only about a month into owning my first diesel. To save the smell and the environment and I'm guessing no loss of power and possibly a little game deficiency, coupled with no issue with oil Blow by I see no reason to not run this stock/properly.

 

Maybe, I was low on compression on cylinder 5 and 7, with massive amounts of blow by, the truck did go thru a gallon of oil every 1,000 miles. And i will agree that the stock CCV is a good design the CCV do smell horrible when in city driving specially with a hurt engine.
