I have a 462 ford motor that my lifters are stuck any ideas?
Are they stuck with carbon, rust or damaged lifters?
Squirt/pour a quart of Marvel's Mystery Oil into the lifter bores and let it soak for a few days.
Not stuck in the lifter bores there Hyd. Lifters but acting like solid lifters
cam lobes are worn down and lifters are noisy----------------
do the lifters/push rods spin as the motor runs?????????
Stuck plungers, as RSpears suggests, try some Marvel and let it soak, do you have one of those tools that can hook onto the rocker? Maybe use it to push down on the plunger? Flex the spring...Quote:

If they are stuck, and you can free them up, consider replacing them as the operational life is probably limited or used up, if they were rusted inside the little seal will probably get damaged by the rusted surface.
Just an opinion of course.. you can verify they work once it's re-assembled and test run. Good luck and let us know how it works out.
