Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Unfortunately If the engine was ran with out oil and revved then its not likely replacing the bearings is going to fix the problem, its more likely there was damage done to the crankshaft journals as well and if that is the case you are likely looking at major engine damage and in most cases that dose require replacing the engine. Before you consider trying to drive the truck you need to remove the oil pressure sending unit and install a oil pressure gauge and monito the actual oil pressure, if you find its still dipping then that means the crankshaft journals as well as the bearing are shot and you do not want to drive the truck anymore until the engine is either rebuilt and or replaced as its will very likely cause the engine to seize .You want a excellent 5 star answer & I would like to be rated the same for providing it.

Unfortunately the oil pan can not be removed with out raising the engine to get the clearance you need. Before you go to that level, install an oil pressure gauge and see if its still dropping. If the engine is not making any noise you may be able to save it but the engine will need to be lifted in order to get the pan off.
Yes you are likely going to find some shaving in the pan and if you have to change the bearing you are going to want to change rod bearing as well as the main bearing and that providing the crankshaft is not damaged with scoring.
He is correct about repairing the engine verse replacing it but your not going to find a good running engine for $100, a fair estimate for a good used engine would be about $800 ball park depending on market pricing in your area.Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.Thank you again.
