Need some rocker arm input
Hey guys, a buddy of mine is having an issue with rocker arms breaking. The truck ran for 2 to 3 mins and broke a rocker arm. He replaced that one then broke another one after a couple more mins of running. (different cylinder, same side), both of these were on the exhaust side. The truck sounded fine until it broke.
The truck was in an accident and he has swapped the frame. The impact was on the side that the rocker arms are breaking. Pushrods are fine.
