Snapped pushrod

[DRWDRW]

Probably due to a problem with the covering on the metal push rod support, missing or worn thru allowing push rod to ride on the bare metal. I expect a new rub block would have cured the problem.

You're right - when the previous pushrod snapped, it had worn the metal guide plate and the black plastic square. This time, though, all three parts - pushrod, plate and plastic support - were new.
