Two problems here: first, the rubber disc(s) will compress on the block side of the motor mount assemblies. This stresses the upper mount bolts, which will break or unscrew and fall out. Cheap fix is to rotate the discs 180 degrees every few years so the compression is spread out and never gets to the wedge shape that breaks bolts. Too late for those discs pictured, though.

Second, if you run the engine hard, heat from the left header will quickly MELT aftermarket polyurethane discs, causing much trouble since the left side mount must first be disassembled to remove from around the gearshift rod, and melted poly runs all over the assembly, then hardens. We had to chisel it off in place on the engine in order to separate the mount, before replacing the mess again with OEM rubber. This happened with new poly discs within 15 minutes at a track event. Good luck-
