here is a picture of the 71 k161 all put back togeather. was thinking a bit about what the heck happend here. i'll admit, i was running her hot and hard. after a bit, we started to loose power, had to use 1st. gear to get it in the shop. on our way up the drive, a flame appeared out from the muffler, then came the knocking. i shut it off right there. about a hour or so, i started it up and the knocking was still there but no flame this time. and just that quick, she went silent, only the s/g on and running. so there was very minimal time from the power loss, to the flame, to the knock. now i know the crank is super strong v.s the piston and connecting rod. no bearings in the c.rod, as made. guess the rings went, then the piston. looking at the picts. i've all ready posted, its funny to me how that c.rod buckeld and the big scuff on the piston. so my question is: would it be possible at all for the crank not to be damaged too bad, given the time it all went down, the big difference in the two materials. if i can get an "out of round " reading of the journal with out removing from block, having the cyclender honed and new hardware, i would be in good shape. but i never broke stuff like this and dont realy know the very extendent of damage caused by. i'll clean with emery cloth and go from there.
