Stantheman,

can you elaborate on the intake bed pan gasket causing oil pressure problems please??

 

djg0770, stantheman was talking about oil useage, not pressure. A common problem on the Magnum engines, particularly the 5.2/5.9, was bad plenum (intake) gaskets, which, as stantheman said, was characterized by oil consumption, and oil "wetness" at the bottom of the throttle body (if you looked down into it).
You can read the TSB via this link, and a how to via this link.

 

One customer at my shop has a 94 3.9 magnum dakota with over 480,000 miles on both the original motor and transmission! Another one had another 3.9 magnum dakota with over 350,000 until it got wrecked.
