I have a 95 GTX that had the four manifold bolts loosening or snapping off. Replaced them with Locktite and lock washers and I tightened the two pipe bolts (underneath) that have the rubber grommets (added new rubber) but still concerned my engine mounting bolts may be loose. I torqued each bolt to spec but if I grab the engine and tug hard it still moves. The bolt that is left front seems to move almost a 16th of an inch. Is it possible that I am missing a shim? Is there an easy way to check the shims? I am concerned that if I run the machine and its out of alignment I will have worse problems. Thanks!!
