So I have repeatedly had this issue wwith losing oil knowing my engine never used/burned any until this last oil change. I started having this issue with oil all over the front of my engine too. Nothing insane but it started affecting my belts badly. Tonight i had a suspicion about a threaded hole right under my intake manifold and washed everything down at the car wash. Sure enough i had another light trail leading down from it after returning home. so i popped the hood on my 98 GTP and it has a hex plug in the same hole. I am guess it is a return port since I never got any negative side effects and its been atleast 4k miles.
Anywho, does anyone know the thread pitch sizes for this hole so i can fill it? or if all 3800's have this. I could easily swing by the Pull and pay after work.
