Blowby creating in cab smell

[camobronco]

Hey guys. Let me just start by saying this site has been an amazing tool for all kinds of info for my new truck. About a week ago I purchased my first Powerstroke. It is a 95 F-350 Crew Cab 4X4 long bed and I absolutely love it. Since the truck is 17 years old there are some minor issues that I have been addressing. One that bothers me the most right now is the in cab smell that I am getting with blowby. I did the blowby test and it is not that bad, just the smell is getting into the cab. I also checked for up pipe leaks, and everything looked good there. Do you guys have any suggestions on how to keep the smell out of the cab? Maybe divert the blowby smoke somewhere? Thanks

do you have a CCV mod done? If so you may want to make the hose longer if it doesnt hang low enough you may be getting blowby in your grommet holes in the firewall.

I do not have the CCV mod. I probably should, though.

CCV mod takes 15 minutes or so to do.all you need is a hose clamp and a 3-4 foot section of rubber hose. pull the small black square box on the drivers side valve cover off and flip it 180 degrees and clamp the hose to the opening. Make sure you dont have any kinks or real sharp bends in the hose, which would result in not adequate venting. You will also need to plug the hole in the silver metal intake tube or take the whole thing off and build a custom intake. also easy to do.

The stock crankcase vent tube is an elbow that attaches to the bottom of the intake tube that goes between the air cleaner and the turbo. If it has been modified a hose will run down the side of the motor. I have a 97 with 308,000 on it and I have the stock ccv and I don't have any issues with odor.

The factory CCV could be clogged. I am going to check it in the morning.

if your CCV is clogged you would know it. Your engine would be yelling at you.

Well, I did the CCV mod and ran the tube all the way to the rear axle. I plan on running that until I get a little oil drip, then I will fab up the catch can. Come to find out not only was the CCV creating an in cab smell, but the smell was coming in the busted shifter boot. So, that leads me to my next thread.
