I took my truck 4-wheeling and got water in my oil. On the way home the oil pressure dropped to 0 and my oil light came on. The first thing I thought was the oil pump was bad. So I changed it 2 times with new oil pumps both times and they both have 40-50 lbs. oil pressure when you first crank it up. But when it gets hot the oil pressure drops and the oil light comes on. Any one have any ideas on what my problem could be? I have a 97' Dodge ram truck with a 318.

chances are as you continued driving , [even a short distance with the warning lamp on] bearing damage has been done and clearances have increased to the point that when warm, the oil flow is pissed away. resulting in a major pressure drop. throwing a set of mains and rod bearings may not fix the problem either as cam bearing wear may also be excessive [your looking at engine removal and complete overhaul] and a skilled machinest should be consulted on the reuse of crank and cam shafts

Yeah unfortunately, the main and rod bearings are not usually affected by coolant nearly as much as cam bearings. Antifreeze acts like acid on cam bearings. sounds like you're looking at an engine overhaul.

You may have a small particle of dirt in the oil sender orfice.. Change the sender unit and hope thats it..
