Here's some info on how to do it, guzzle also shows how to make an oil trap for his.

The H2E kit has a provision to vent the crankcase back into the intake, I think, anyway. Or is this a provision for a power adder (I did buy this second hand, and don't know what it should look like).
Thanks, Robby

Personally, not a big fan of the CCV mod. Don't see a point in it. Just a stinky mess as far as I'm concerned. Some drip, some don't. Stories of oil soaked turboes and oil filled intercoolers are, IMO, mythological bs.
The 'provision' you speak of is indeed for the crank case vent.

About the condensation. I was really concerned about that for a little while, but am no longer. After running my "trap" under the cab for several months during cold weather, I collected about 3-4 ounces of black oily stuff from the trap. I sealed the jar and let it sit to see how much moisture condensation there was in that oily stuff. After letting the jar sit for four months, completely untouched the entire time and never moved... absolutely NO water... it's all oil.
Point is, if you run the hose up and over the MC, any condensation you get will be nothing more than oil, and it won't hurt anything to have that run back down the hose into the crank case.

The point in favor of a CCV mod is that without it you can blow off the CAC boots which happened to me several times while towing long mountain grades. But even the least restrictive CCV mod increases CC pressure from a negative 4" or so to a positive 3", and this can be enough to cause other problems that are even worse than blown boots.
I think that anyone with a CCV mod should have a gauge to keep tabs on their CC pressure. By measuring the amount of blow by you get an instant status check on the health of your engine. Also, if a beetle bug should crawl up your vent hose and get stuck, you'll know about the problem immediately instead of finding it when seals start leaking.

Also, given the complete lack of condensation during warm months taht I've collected some 6' downstream of the doghouse in my trap, and the 3-4 ounces collected in winter months, I also find it hard to believe that this uphil climb made by my hose for only the firs t8-10 inches right off the engine will provide enough time for any significant condensation at all. Yes, again, I know that on an absolute basis it will happen, but if I'm only collecting 3-4 ounces at a much cooler position downstream of the doghouse, and those 3-4 ounces being collected over a period of some 6-8K miles... the amount of real condensation at the higher temperature position within 10 inches of the doghouse cannot be significant to any degree.

To address an earlier post, oily boots and I/Cs is definitely *NOT* mythical BS. The reason I found this site is because my boots were nasty oily and the orange ones were leaking and causing oil to collect in the valley and eventually drip down the back of my engine. When I did a search for 7.3 oil leak or something similar, I found this site. Now that I have done the CCV (my first mod!!), no more oily boots and I haven't had any oil drip from the end of the hose. Mine is run back to where the exhaust is -- no problems with smells or anything like that, and the little bit of smoke goes unnoticed since the exhaust is right there.

My buddy has an international truck, the CCV vents straight down the back of the motor. A little smoke hardly no smell, unless you stick your nose near it. And no problems, at 126,000 mi. on it!! I have mine going up over the brake thingy and straight down 2.5' ..

Let me also add that my observations are that with my Schaeffer oil, I am getting more vapor out the end of the hose than I ever did with the Amsoil oil, which would also lend itself to an increase in captured condensate in my trap if it were a simple matter of what you described above.

By the way good to see you on, Joe!

Does anyone have problems with condensation freezing in the tube causing problems? I am wanting to do this mod on my X, its boots are a filthy with oily residue. The funny thing is my pickups tubes are much cleaner than the X and it has nearly double the miles on it.

Now to answer your question, yes, there have been posts here of the CCV mod hose freezing up and causing a problem, but I am not sure how unless you leave a long low spot in the run for it to collect in. Even then, with a big enough hose and long enough run, it would not clog up, rather evaporate as the truck is run. Bottom line, avoid a big low loop in the hose if running out the rear by the axle.

humm, now i have a different story,turned the elbow too the drivers fender and ran mine straight down to the frame rail with only about 4 ft. of hose, and it dumps at the frame under the drivers door, and i do get drips, and loads of oil fume from it, (smokes like a chimney) i noticed tonight that when i get on it hard, it really blows as i could see it in the guys head lights behind me and it wasnt black.
I however have loads of power, any one have an idea why some seem to smoke more than others. TYPES OF OIL MAYBE!!!!!!!!!!!
