Tinny rattle - if the crank pulley turns clockwise when looking from the front (usually do), the engine will lean to the offside under load, so look at what might be catching.....air box is a likely culprit. Something could be catching the bonnet hinge???
Door hinge knock - try moving the screen frame upright, see if that makes the noise. When did you last lubricate the bonnet tapes???? Mine developed an insane creak from the nearside screen pillar, which disappeared completely when I put some Vaseline on the tapes.
