Engine Pinging

[Razor]

How come there's not much of us 240K guys posting

where's everyone gone?

well anyway

Yesterday I started my car and lifted the bonnet and I heard pinging noise, sounds like when you shake a can of spray paint.

I think i can hear the noise stronger just under the rocker cover.

I just only heard this noise yesterday

I use unleaded and sometimes LRP

but I dont use this car that much....

Valve chatter.

Usually you dont experience pinging (detonation) unless the car is warm and under load. That is the time you most likely will hear pinging.

It might also be preignition though as well.

well the noise is actually louder when the engine is cold, when engine is under load I cant hear pinging noise.
