Have a 95 seville sls 4.6L. Ran over something on the road and it cracked the oil pan. Got the vehicle home by putting in oil every mile. The stop engine light only came on only once and I pulled over and refilled with oil. I understand the only way to remove the pan is the take out the engine, so I patched the pan with epoxy. let it dry 24 hrs refilled with oil, new oil filter and everthing was ok. Drove to the gas station turned off the engine and when i turned it back on the low pressure light came on and the engine sounded like it wasn't getting any oil. I'm thinking its the oil pump, how can I check for sure without removing it and how difficult is it to remove. Is it behind the cover behind the belt or is it in the oil pan? Any thoughts would be appreciated.
