Low oil pressure light on my '04 4.2
 

Hey guys. My 2004 4.2 Allroad just had the dreadful oil pressure light come on today about a mile from home. The car has 263K on her. The oil is full. I'm thinking that the pick- up screen is clogged. I am running 10-40 Mobile 1 because of the milage and oil consumption that has been very good as of late. I'm thinking that the pick-up screen is clogged or the pump is going bad. I haven't been under the car in a while since selling my tools and moving into a apartment. My question is, is there any obstructions in the way for a mechanic to drop the oil pan? I'm at the point of putting money into fixing it or the boneyard.
