Engine Mounts for the 928
Up until '83 our cars had solid rubber motor mounts and in many cases they are still in place today with no problem. The concept of fluid filled MM's was a good one except for the fact that they leak and collapse, as the bulk of the support is a pocket that is now empty.
All my cars (and I have a few) have the solid rubber mounts made by another company other than Anchor. Anchor are fine except they use the same part number (2698) for both the solid and hydraulic MM's. This means that a lot of people have no clue if they fitted hydraulic or solid MM's until the premature failure.
I have two GTS's, one with Porsche MM and the other with my solid rubber MM and there is no difference in the smoothness of the feel of the engine at all.
In fact I would say the solid MM are slightly better. Big dollar difference too, $600 vs. $75.
