As for those engine leveling devices, while I've never used one, I see their attraction.
As with ANY threaded rod under load, GREASE THE %^&$ THING!!
There are some specific tools I use for pulling out HUNDREDS of BMW suspension bushings, and I've seen ametuers barely make the tool last through two (<2) jobs because they don't grease the bolt.
Every electrician knows this, because of his Greenlee knock-out punch set :wink:
I had to laugh watching an episode of "OverHaulin" last night, when a burly guy was strggling trying to turn the crank on a leveler (572 BBC hanging on it...); while theirs was definitely a cut above HF (with what looked like an enclosed bolt) I guarantee that it had not been greased. Those guys should know better, but then again, you see the clowns using an impact wrench to hammer (expensive) wheels onto Lamborghinis (leaving the owners to wonder why the rotors warp the first time they get them really hot...).
