After a long, on and off, restoration (not the motor) I finally got the '74 on the road. Took a few test drives to the gas station, working out minor glitches and within 10 miles, I hear a knocking sound, like a rod knock but less consistent. Maybe broken rocker. I drained the oil and found a few tiny chunks of metal and the rest had a thin paper consistency. I believe it's the bearing material. Anyone?
Thanks for any input (before I pull the engine out. ![]() |

Old school:
Puling the plug wires one at a time was a way to find the rod knock. When the knock stops with a plug wire pulled you found the bad rod. My knock turned out to be the cam thrust bearing. Knocked on cruise and idle. Then under load the knocking stoped Mine too had long strips of babbit bearing material in the screen. |
