Sat, 15 February 2003 14:35 SPEEDCORE wrote on Sun, 16 February 2003 00:00 .......on the life or strength of the rocker arms or is failure a direct result of constant operation in the high rev extreams??? M series engines also have rocker arms. My friend and I built a 4M/M hybrid which could rev very hard indeed, but being tight stooges, we didn't replace the valve springs. We had a breakage at above 7000 rpm. We think failure was probably due to excessive rpm with standard valve springs with the sequence going something like this: lumpy cam, soft springs with poor control of valve at high rpm, valve hits piston, valve ricochets back into rocker arm, snapping it off. Happy to hear other people's thoughts on this. [Report message to a moderator]
