we pulled a valve cover and the #1 stud was snapped off and the #5 had a pushrod that ground through the rocker arm. what could cause this? this is the scond time snapping a rocker stud on #1 its a bbc

Pat, you've got something going on in the geometry. What rockers? What's the lift on the cam, type of cam, etc? Give as many details as you can.

 

[ol guy]

Yeah what sc said. First geuss coil bind. M

Definately have some incorrect parts choices and/or set-up.

My first $5 guess with knowing no info yet - stamped steel rockers that aren't clearanced for the valve lift and the slots are hitting the rocker studs. 2nd guess, but just $3 this time, major valve float.

Stock rockers!!! They are only good for .525 max lift. the slots hit the stud and rocker splits. At th very least get long slots. Stock rockers with that cam, you found the problem BINGO. M
