Was not posting in 2012, but can let you know exactly what is happening. The front frame crossmember where the engine frame stands bolt, that area has slightly sunken in. Either that, or the entire front crossmember has fatigued slightly causing the mounted engine to settle.
Have had to solve this same problem several times, it's a pain, ESP forking the nut or bolts out from under the frame crossmember, then reinstalling.
Basic process goes like this
- unbolt the long motor mount bolts, lift the engine (personally, i prefer to carefully pull it out of the car).
- carefully unbolt the three nuts on each corner of "stretched triangular" frame stand,
- trace the pattern of the bottom of each frame stand onto cardboard, then onto 1/8" plate steel.
- cut the steel with a cutoff wheel or plasma cutter, and finish grind the edges.
- drill the three holes for each side plate, don't mix 'em up, taller frame std goes on drivers side.
- carefully sandwich the spacer between the frame crossmember and the frame stand.
will usually need to fashion a piece of old welding rod or to help line up each hole.
-carefully tighten the 3 bolts, lock washers, and nuts down.
-reinstall or lower down engine. if engines just being lifted, make sure and mark and remove distributor, so don't smack it up against the firewall. Going to only raise, also need the drop the head pipes and watch engine harness and clutch linkage.
