Ford 99-03 7.3L Powerstroke Crankcase Vent Bypass Mod

Ford 99-03 7.3L Powerstroke Crankcase Vent 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.


  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!
