Rocker arms getting loose
How common a problem is the rocker arms working loose in a 6.0.
We have 2 of them that this has happened on and 04 f-250 and a 05 f-350 model. The 04 got so loose it bent the rocker arm jamming the intake valve partially open.
This caused popping back thru the intake. We had to replace the rocker arm assembly. Luckley the valve did not get bent.
We have about a dozen more in the fleet that have loud clatters of varying degrees that we are beginning to suspect that this is the problem.
