    Put this kit on when I upgraded my turbo to the 38R. Nice to not be venting oil into the intake anymore!

    Great kit, great price.

    After doing some looking around I decided I couldn't even put this kit together for the price they charge. Very easy to install and comes with more then enough hose! Instant gratification on start up seeing crankcase breathing externally. Would recommend to everyone with a 7.3L.

    Keeps Oil Out

    Easy install with instructions. Does what it's suppose to do. Can get some diesel smell in the cab at times but not overbearing.

    Get Oil Out of Intercooler

    Posted by Larry on May 22nd 2017

    While climbing the mountain in Colorado one of the turbo boots popped off and I had to patch it & reattach it along the side of the road. The boot and the intercooler tube were full of oil. It was then then that I decided I needed to do the CCV Crankcase Vent Mod. Replaced the turbo boots and cleaned the intercooler & tubes, and now have the CCV Crankcase Vent Mod in place to keep them clean. This is the easiest mod I've done on the engine to date.

    One handy kit

    Posted by Unknown on May 14th 2017

    I ordered this kit at the same time I replaced my failing cac boots. They were full of oil and dripping into the valley of the motor making a huge mess. I installed this hoping to avoid the problem in the future. Was great to have everything in one handy kit. Hose was long enough to get to the rear door of my crew cab. Wished it would have included one more hose clamp to replace the lame factory clamp, but that was an easy fix.

    This is a great kit to get. Not much too it and easy to install. Good idea to get it since your dog house O-rings should be replaced anyway. Keep all of that oil out of your intake and get this kit. You will notice a bit more of the diesel smell since you are venting to the atmosphere but not a big deal to me. I like the smell of it anyway. Can not tell in the truck only if you are standing next to it while it is running. Great parts and an overall great kit.
