hi i done the head myself. it was aparently rebuilt by a company 1500 miles before i had it and i stripped it and reseated valves anyway but they all looked good at the time! Unless one of them is so slightly bent i never noticed? But the thing is this wouldnt make it rattle would it, and it still drives well when accelerating. Wouldnt this still make the noise even though i disconnect the ht lead for cylinder no.3 or would it only show under load.
ARghhhh Im going mad now.
