Pushrod problems
 

I was taking my engines apart for some winter maintanence and I found half of my pushrods were cracked. These are the reccomended Crane pushrods with pressed ends that you would use with a 741 Crane cam. They have about 100 hrs. on them. Any ideas what would cause this. My spring pressures are 150 seat and about 470 lb/in. The springs do not coil bind.
