    I have a 97 Dakota with a 5.2 and have a question.It has the barrel style intake and has started running rough and using oil.Does the plate on the bottom of the intake go into vacuum or is it just a shield?I saw the gasket related to the pan and thought maybe.

    vacuum. Look down inside the throttle body with the butterflies open , you will see oil laying in the bottom if the seal is bad.

      pull the PCV valve and put your thumb over the valve cover hole feeling for some suction.
      If the lower gaskets leaking it'll pull vacuum through the engine crankcase

      It’s not a bad job to do. Felpro makes a good metal backed gasket.

      Hughes I hate to use this name in public.


      Hughes makes a repair kit to solve your problem. Others on this form have made their own plates so you might look that up.

      Well yeah, lol, it IS I've tore down a few of those engines and the majority of somewhere around 8 have broken / corroded off intake bolts. Evidently the aluminum intake does not go well with those bolts

      I had to do that job once; didn't enjoy it one bit. I finally took the front
      wheels off. After that it wasn't so bad,lol

      Thanks for the info guys.It sounds like my problem with the oil use and all plus I have a vacuum gauge on the pillar and the vacuum has been dropping off,down to 15 inch's at idle.I hope it will wait till spring with no place inside to work.
