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.  |

"Garry glitter" is a new one for me. Sounds like a Vegas Elvis imposter.
Pulling (or shorting, this is easier) plug wires will not hurt an engine in any way, doesn't have to be bad already. The only thing it might hurt is YOU if you're holding that wire when you pull it off. I'll normally pull the boots on the distributor cap back and just use a test light to ground each tower. Works fine and no SPARKY. Cylinder shorting is a common diagnostics procedure that has been around forever. Don't try to do this with COP setup. Those can have enough ZAP to stop your heart. Still will not hurt the engine however... I am in agreement with the others. It's done, time for teardown. No need to shock yourself unnecessarily... |
