Knock tap ping on start up and high rpm under load
I have a 95 ford ranger 2.3. Haveing a problem at startup low oil pressure for 6 to 7 sec then runs normal until 3rd gear and up at high rpm pings and knocking noise any ideas??? Have dropped oil pan and checked pick up tube nothing cloging it. Could it be pump or tapets ???

Make like what sounds like valve noise at high rpm under load and there is no carbon build up and egr valve is clean it is not spark knock I know that much.
