Took the engine oil pan down cleaned every thing up changed the filter l and filled it with oil before putting it back up ) on the pan put everything back together and filled the oil to the proper level and now I don't have oil pressure Before I did all of this everything was working perfectly oil pressure was good didn't hear any ticking of the lifters nothing . The only thing wrong was the pan was leaking oil around the edge ! Was just wondering if any one had any ideas of was would cause this ?
