Blowby Creating Smell in Cab

[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

Does it have a CCV mod done?
I would guess it does cause factory is vented into the intake. I'd just move the hose somewhere else.

[camobronco]

No, it does not have the CCV mod. I wonder if the factory vent is clogged. A little bit of smoke is coming out of the dipstick, which in turn goes right to the vent for the A/C, which puts it right in the cab.

Oh, that's not good. Unless the dipstick isn't sealing good.
If an OBS is the same as a SD, then there is a 'doghouse' on top of the driver side valve cover that has a short hose going into the intake. That's the CCV.

[camobronco]

It could be a combination of both.

Sorry, but can someone move this to the 94-98 section please. Thanks.

Nevermind, just delete. I will re-post. Thanks.
