Hi all,

Video below has sound.

Its like a rattle sound. It goes when accelerate.
Assume is air flow related. Mechanics cant hear it when under bonnet with all other engine noises.

I have recently had large works done to fix a misfire which I thought might have fixed it but it hasnt.
Fuel injectors x8 + plugs
Primary and secondary drive belts
LH and LH manifolds
water pump, oil cooler + pipework

Any ideas chaps? Chasing this noise is getting expensive!!!
