Over reving the engine, ( to many RPM )
The rocker arm nuts need replaced ( The locks are worn out on the nuts )
The rocker arms are worn where they set on the valve stems.
Need to check everything closely.
PUSH rods and rocker arms... yes.
yes
Pull the valve covers off. loosen the rocker arms with out taking them all the way off. then you can turn the rocker arms to pull the push rods out. replace push rods, and tighten rocker arms back down and put valve covers back on
On the v6, yes
If the heads don't have push rod guide plates, the rocker arms will set off center just a little. But if they are way off then you must have a bent push rod.
To remove the rocker arms on a 1992 Mazda B2200, first, ensure the engine is cool and disconnect the battery. Remove the valve cover by unscrewing the bolts, then carefully lift it off. Next, loosen the rocker arm bolts in a crisscross pattern to avoid warping, and remove them along with any pushrods. Finally, take off the rocker arms from their shafts, noting their arrangement for reassembly.
On the 4.7L engine it can be caused by failed lifters.On the 4.7L engine it can be caused by failed lifters.

YES IT IS. THRE IS AN OPEN LOOP INTO THE CRANKCASE AND ALLOWS OIL COMING OFF THE ROCKER ARMS AND OVER THE TIMING CHAIN TO COME DOWN AND RETURN.
Most likely bc a valve broke and hit a cylinder which then pushed the hydraulic lifter up breaking the rocker arm
Rocker Arm problems, specifically with them falling off, are common with 2000 JGC's. You can get the code read, which will point to the cylinder that has the failed rocker arm and then remove the left or right rocker cover to inspect. The problem with the falling off rocker arms tends to be a slippage of the valve guides that leaves the valve to hang up and removes the stress from the rocker so it just falls off. Replace the heads. Replace the HEADS? Sounds drastic. How about repairing the heads?
Tighten the rocker arms down all the way and then losen them 3/4 a round off
