I have 190,000 miles on 5.4 engine. Use Mobil 1. Burns no oil. How long should my oil pump last, and what is a sign it is failing? Thank you.

Oil pumps generally outlast most other parts of the engine, if maintained well that is. If you have a sign of low or high oil pressure the first thing to do is check the pressure with a mechanical gauge, because often it is the oil sending unit that has failed. If the oil pump does give up though it usually makes some noises and will cause the engine to knock due to lack of lubrication, your instrument cluster oil light should come on as well as the oil pressure gauge reading high or low (if equipped). Unfortunately, usually if the oil light has came on then it's too late because the engine is probably shot.
