Crankcase Bypass Mod
http://www.puredieselpower.com/catal...nkcasevent.jpg
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! |
What kind of increase in fuel econ? power? Seems like it would also reduce maintenance on the intercooler as well.
do you have this on your PSD? if so, how long? Rick |
I Personally Do Not Have It On My 6.4L Seems To Be A Hot Item For 7.3s.
|
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. :up2:

BD Crank Case Ventilation Kit
I just did a give away on the New BD Crank Case Ventilation Kit, they work great and look like and OEM installed product.
More information is available at BD CCV Kit |
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.

Keep us posted! |
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? Rick |
I have mine vented to air behind the fuel tank. Works great!

CSIPSD,
Thanks for the input. I found a kit wtihout the accumulator for $80. From your signature you have done a lot of mods to your rig. Were they for performance or fuel economy... Can you break down these mods and what they did for you? Rick |
You don't have to buy a kit. You just need about 5' of 3/4" heater hose, and something to plug the hose on the intake.
I just ran mine down behind the front wheel. I haven't noticed and performance or better mpg though. It does let your boots stay cleaner. |

Ya know I dont want to think about it... 20k maybe a bit more... and cost me fuel milage... and a new motor... and about 4 trannys... But she sure is fun to drive at 450-470 hp!!!:choochoo: |

Where can you get an accumulator?
I think it might be best to keep the line short, and place an accumulator near the master brake cylinder. If doing the mod is supposed to keep the intake tube clean, then why would I want to vent it near the truck (front tire wheel) and dirty the bottom of the truck? If the hose can fill up with junk, I don't want to run the risk of the hose plugging by running it to the rear. I don't understand how the engine compartment gets dirty when hooked up to the intake. Doesn't the intake receive the CCV and recycle it? So how does it get all over the engine compartment? If the hose gets plugged, seals leak. I'm not sure if the seals leaking are permanent damage, or if unplugging the hose would remedy the problem and no harm done? ---AutoMerged DoublePost---

Who is going to spend $335 for this kit?? It's a nice kit...but way too much money. I'd pay $50-60 for a kit like this. For anything more, I'll just run a hose to the back, or figure out some DIY. Maybe someone could come up with a part list for us DIY types. |
BD makes some good products, but there is absolutely no reason to pay $335 for something that shouldn't cost anymore than $5. If you want to put an accumulator on to be more environmentally friendly, you can make one out of PVC for probably $25. Do a search over on PowerstrokeNation.com. There is plenty of information on there about how people have done the CCV mod. Personally, I just ran a 3/4" heater hose down by the back drivers side front leaf spring mount. The only time I can smell it is if I've been runnin it hard and have the windows down at a stop light or drive-thru. Otherwise I never smell it or have any oil drippin. Don't forget to plug the spot where it goes into the intake tube. I just bought an assortment of vacuum caps at Autozone and the biggest one fit perfectly.

i did it and recommend it. however, route the vent hose to the back of the truck or tap into the exhaust. if i dumps under the cab, it stinks up the cab at idle

I agree it is a higher investment and the solutions you mention do work! For the guy looking for a clean, OEM look install and zero smell, especially at the stop light and drive through window the BD CCV kit is great. If anyone is interested let me know and I will see what I can do to lower the price for forum members. |
Yes, it is a nice kit. I'd love to have one so I don't have to smell the CCV, and neither do the other drivers. But the problem with some of these professional kits is that someone made them way too nice, and that ends up costing a lot.
Right now I'm looking for ways to save money. If I have to smell some crankcase to save $300+, that would be fantastic savings! There's a lot of other stuff I can do with $300. We need something simpler, so the cost will be less. I'd pay $50...maybe $75. |
