    Hello all. I have been searching for the answer to this but cant seen to find it. I have a 01 with the V6, On the passenger side at the fron of the valve cover is a vent with a hose running to the throttle body. Has anyone ever tried disconnecting this hose and plugging the hose so you arent sucking hot air and blowby into your motor? Dont know if this would hurt anything. Any help would be great!

    Mostly stock for now, I have added a cb radio, various cheap mods and I plan on adding aftermarket wheels and other items in the future.
    Just leave it............

    the problem I am having though is with the blowby oil getting into the TPS.

    I think you are referring to the PCV valve. It is a little plastic elbow with a check valve in the bottom that pushes into a rubber grommet in the valve cover and has a vacuum hose on the other end.

    This is an important component of the emissions system and should cause you no problems if it is working correctly. I don't know why you would want to remove it and plug the vacuum line. If you were to do this you would have to install some sort of breather vent on the valve cover in its place but I would not recommend doing that.

    Yes you are right. It was the PCV valve I was refering to. I just dont like the ammount of oil that is entering the intake, I actually think it is effecting the TPS and I know it is making a mess inside of the air passages. I clean the oil out of the TB at every service because there is usually about 2 teaspoons of oil in there by then. I dont know how common this is. the truck does not seem to use any oil at all but the motor does have 229,000 miles on it.

    The pcv has a one way check ball in it, it may be stuck. I would change it.

    if changing your pcv doent work u can vent it. when i had a vehicross most of the guys had theirs vented because the pcv valves on those loved to stick open and suck oil. get a mini breather filter at any auto store for bout 10 bucks. its like diff breather tubes, the hot expanding air and escaping gases just need somewhere to go

    Great thanks for all the replies. How would I go about cleaning the pcv? I have never done it before, what should I use to do it? And if I do go with just the breather I can just take out the pcv and pop the breather in right?

    To clean it just spray inside it with brake cleaner with it off your truck. spray in both ends untill clean brake cleaner comes out. It should rattle when you shake it, the check ball moves around it a little.
    If you go the breather route just plug the vac line and push the breather in.

    Ok problem solved. It wasnt rattling so I sprayed the crap out of it with some TB cleaner and it started rattling again. Doesnt seem to be sucking oil anymore. Thanks again for all the replies.:)
