If there is a gap in the torque stop pieces, the motor mounts are likely toast.
If you can not remove the IAC without first removing the engine fan shroud,
they are toast.
The gap from sub-frame to oil pan would also be a sure fire test but I don't
know what the distance should be.
If you get a clunk under your feet under hard acceleration, they could be toast
but this could also be a bent cross member (courtesy of your local tire shop)
or the exhaust pipes are hanging a little low.
Basically, if they are original they are probably shot. You will be amazed they
were able to hold your motor in. I pulled the engine mounting stud out of my
old mount by hand.
The new ones have a heat shield that hopefully will make them last longer.
