i have the same problem, starts fine, knocks for a few moments and than stops.
knocking i'm fine with, its the clack clack bang, and finally the broken rod taking out my oil pan then tire and sending me into a ditch.. thats the part i worry about

that would not be good. but would be a good reason for some upgrades.
