Re: [AMC-list] caspers rod is toast

[Frank Swygert <farna@xxxxxxx>]

Well, if you need another rod I have a 62 or 63 motor that I've removed one from for someone else. It's yours for packing and shipping if you want it. I doubt the crank is messed up so bad it needs to come out, the rod usually gets the worst end of the deal. I wouldn't drive it too long with the thicker oil since it's pounding around in there. 

The rod weight differences are mainly from the years. Earlier rods will be heavier, but I don't know where the difference is (what year). That AMC kept the same casting number doesn't help! These engines aren't real sensitive to balance, I don't think one lighter or heavier rod will make a noticeable effect on it.

so, i tried a few things on casper. thicker oil (20-50) the knock went away
for a little bit, but i was POSITIVE it was a bad rod. well, someone had
suggested to pull plug wires to till it quit knocking trick. yup, same
cylinder i lost the rod bearing in last summer. i know that bearing was going
bad for a while, but could NOT hear it till there was no bearing left. these
196 cast iron blocks are so thick, you cant hear anything in them. it had
probably been bad for a while, i just couldnt HEAR it till there was no
bearing left. meaning, the rod had been punding around for a while. now, it
is beat out of round. it knocks HORRIBLE above 2500 rpm.
