What causes a Briggs Intek bent push rod to fail?
Deere, Husqvarna and many others. The failure on that engine consists of it overheating either because of long duration between oil changes or because of insufficient air flow keeping the cylinders cool. Intern that causes the valve guide to hang on to the valve as it is going in and out of the cylinder and causes the guide to push out.
Is the intake push rod straight or bent?
The valve guide is in position yet, and the intake push rod is straight (it had bent last time). I have to pull this thing apart again, but I was just wondering what the heck could cause this trouble? The engine has about 273 hours on it and it was around 262 before the first push rod went.

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.
