Crankcase Bypass Mod
This Crankcase Vent (CCV) kit is designed to re-route your crankcase vapors and oil away from the intercooler and turbo toward the rear of your 99-03 PowerStroke 7.3 diesel.
The 4" x 1/8" thick, powder coated tube replaces your stock CV tube and bolts directly to your stock CV brace. The hot custom colored sleeve is powder coated and available in gloss black.
CV MOD ADVANTAGES:
1. The stock CV has an outlet tube inside the sleeve that has a 20% air restriction. This new CV sleeve is open and has no restriction allowing your turbo to breathe!
2. This CV mod eliminates oil from entering your turbo and your air-to-air intercooler system. This reduces oil accumulation in the intercooler system and keeps the intercooler operating at maximum cooling efficiency.
3. You've probably blown a few intercooler boots off your intercooler pipes and "Y" pipe huh? This keeps the oil out of the system and prevents the interconnecting boots from blowing off on WOT. Plus, there will be no more oil blow by around the boots and air intake that causes that oily mess under your hood.
4. Reduces exhaust smoke.
5. Adds that custom touch to match or enhance your under hood look.
This is one of the easiest and least expensive mods that all 99-03 PSD's owners should perform. Just search the CCV mod or CV bypass on any of the Ford PowerStroke Forums and check it out!
Simply remove your stock CV and hose connector. Remove the screws on the stock breather and rotate 180 ° so it exits towards the firewall. Install the 90 ° elbow, hose, hose clamps and route towards down and inside the frame rail and towards the rear of the truck. Attach with tie strips. That's it!

Its a good idear -- keeps your boots clean, which will definately help to keep them from blowing off at high boost levels -- also is just generally cleaner inside the engine bay w/o all the crud sticking to everything
I haven't done it yet, but will soon!

yah, its not a fuel economy/power thing -- just a cleanliness thing and easier to keep your IC boots on kind of thing

You would be amazed at how much soot gets caked up in the intake. I pulled mine apart at 5K and was shocked. Do the mod, your engine and intercooler will thank you.

I did this mod on my truck last fall when I replaced the compressor housing, I was amazed how much oil was inside the boots. I just won the BD Crank Case Ventilation Kit, and as soon as I can retrieve my truck from Colorado I going to put it on. just from what I seen when I opened the box this thing is impressive, looks very well designed and should work great.

OK... I think this looks like a doable afternoon chore that will give good results on the fuel economy as well as clean up the performance. It does however leave me with some questions. After looking around on the net for a kit, I found some that have accumulators with a drain valve.
Question 1: Is there a preferred kit to bypass the pcv?
Question 2: Would an accumulator be a desired option? Is there that much coming out of this hose that you would need a catch can to collect it?
Question 3: My truck has over 100k miles on it. Do I need to pull the intercooler and have it hot tanked or cleaned?
