I have a 58 235 and getting a lot of exhaust smell in the cab which i suspect is coming from the pan breather. I was wondering if I could completely eliminate the pan breather tube if I have a breather in my valve cover?

I have seen the post on converting the breather into a PCV system using the vacuum from the fuel pump, but again, I'm wondering why I need anything at all if I have a breather in my valve cover.

Any advice would be greatly appreciated.

Thanks,

Mike
