Could that be because the engine is idling at higher revs when cold?
Once it's hot, try and raise the revs to say a constant 1100 to 1200 rpm - does the rattle then die down?
I take it you camera was placed on the passenger side of the car? It will get louder when gearbox oil heats up and thins. I suspect this is reverse gear chatter. The reverse gear is located next to the gearbox end plate. Change the gearbox oil for a starter.
Have you checked whether a family of chipmunks are living in the engine bay?
Hope you find the prob mate & get it sorted cheaply, not heard that one before?
I'd be interested to know what the fault is when you locate it.![]()
Don't go there yet Paul:stop:, if you're handy or a mech who knows all this stuff, these kinda probs can often be easy fixes, stay positive until told otherwise dude.if it is chipmunks ill kill the lot of them
have so many thoughts i might aswell get another car it will be cheaper lol
