CHEVROLET ENGINE KNOCK

Engine Has A Knock When First Starting It Up After Sitting Overnight. Knock Goes Away After 30-45 Seconds. Knock Does Not Happen After...

Changed Oil Pump And Oil Filter, Also Replaced Spark Plug Wires And Spark Plugs. Now Engine Has A Loud Knock And Chirp.

I Just Replaced My Head Gasket And When I Started Car I'm Hearing A Loud Knocking That Gets Faster As I Rev The Engine.
