Pushrods don't just "slip" off the lifter.
It sits in a cup on the lifter and in the rocker arm. Valve spring pressure
holds them all together....until . . . .
So, what happened just before it "slipped"? A downshift at too high of a
ground speed? a "wanna see how high it will rev" situation? Is the
valvespring broken? Valve swallowed?
In the first two situations, the pushrod is probably bent and won't stay in
place (replace it), in the second two, repairs are needed before you put it
The final scenario is one where you were working on the engine and it
slipped off while tightening the rocker shaft . . .loosen it up and slip it
back in and retorque.
