  • Top Engine rattle?

    Hi, just wanted to see if anyone else had heard anything similar. I have a worn Camshaft rattle metallic type of noise from the n/s top of the engine ( standing at the back of the car looking forward) i have listened to it through a long screwdriver on the cylinder head and the rattle seems louder above number 3 cylinder. The engine does not misfire and the rattle speed increases with engine speed, and rattles through all gears. i think must be camshaft, conrod or little end trouble, any thoughts? thanks.

    Remove valve cover ASAP to inspect. Will be follower or hydraulic tappet.

              Might be worth checking oil supply to lifter.
