What should I do if my pushrod is bent?
Start the engine and adjust the valves if not equipped with a rocker shaft. Observe the operation of the rocker arms and pushrods to ensure that they are working properly. Replace the valve cover and valve cover gasket. Clean all oil off the engine compartment.
What causes the intake push rod to bend?
The thimble then pushes outward, restricting the movement of the valve spring, eventually causing the push rod to bend. This is a design flaw in current B&S engines. I have no idea how long this flaw has been around. but it’s quite a problem.
What causes a push rod to give way?
It is caused by the rocker arms ball jumping out of the push rods cup, so instead of the little ball sitting in the push rods cup, it jumps out and pushes on the edge of that cup, which effectively opens the valve way too much forcing it to hit the piston, the weakest point (the push rod) then has to give way.. thus bending it.
What causes a pushrod to bend when floating?
A valve is not really connected to the pushrod when floating, so the valve contacting the piston would generally not bend the pushrod. It would bend the valve though.

What causes the push rods on a Camaro to bend?
I keep thinking back to a buddy years back, 70 1/2 RS camaro, his kid took it out and hurt the engine screwing around, and when he pulled the engine apart, the push rods on the 350 were damn near S shaped. 2020…year of seeing clearly for the first time in a while.
