so recently I have been hearing a pinging on occation it sounds like the flicking of an empty soup can. I have pulled apart my motor at 1200 miles now and every thing seems to be in working order. no play on any bearings. but the piston rings do seem to have more play in them than usual. and I have been runninjg it at wot almost all the time. has anyone heard this noise before? I figure it might be the rings snagging but cannot be sure.
