Did my engine mounts, one was somewhat compressed (not terribly but to be expected). Engine stop and AT mount look great. But if I’m doing other work, would like to determine if they are needed. I guess I could do them anytime in the future... but is there a “simple” test besides their look, to see if replacement is prudent?
