Ive got an engine rattle at idle and I cant for the life of me figure out what it is. The rattle happens as the engine drops down to idle when revving up stationary around the 1000-1500 rpm range, the noise is apparent no matter if the engine is hot or cold.
Link to the noise here (im slightly blipping the throttle in the video) : https://www.youtube.com/shorts/lYK-SU07Lyk
Things I've ruled out are
Idle control valve as it doesn't have one
Cam gear tensioner is tensioned
Big ends/ mains just had a full new set of ACL's
Valve shims / clearances are fine (although I wouldn't expect this to cause the noise as it doesn't increase with rpm)
Piston slap (You can hear the piston slap on cold start and its more of a dull thudding that goes away when its warmed up)
Cranks in manifold its brand new
Ive had a poke around with a long screw driver to my ear and its a bit difficult to distinguish where its coming from but ive come to the conclusion that its coming from the gearbox side of the engine.
Any help would be appreciated as Its driving me up the wall
