Hi everyone. As I have probably search everywhere and could find anything similar, I'm having to ask the question myself. Have anyone come across this metallic poping, pinging background noise? It only happened when the engine is warmed up. I have took the drive belt off to test it, and noise still there. It comes off the front drivers side part of the engine or so I think. Car has 90k on the clock. Any input will be appreciated as it drives me mad. Whenever I see car with this engine in it it looks like they all make this particular noise but no one seems to know where it's coming from.
Thanks
