An interferance engine is typically described as an engine with a valve assembly where, the lowest point of any valve's extension into the cylinder, is lower than the highest point the piston will reach. If valve timings are altered incorrectly or a valve spring breaks, the valve and piston can collide, causing massive damage to the engine.

What causes push rods to bend?

Typically that's because the camshaft is improperly timed. If a piston kisses a valve you'll usually cause serious damage to piston, valve, head, pushrods... all because a valve tried to open at the wrong time. Another possibility would be a seized valve, but that's far more common in engines that have not been used for a long time. I would say ,possibly a bent valve stem. if the engine has run ok in the past. although the above answer may very well be correct.
