I replaced the engine mounts on my 87 GT 5speed several months back. Recently on the way home from work I felt a small pop while decelerating to a stop. After that I am getting a sort of slapping or vibration as I let the clutch out. I knew my clutch had some minor clutch chatter, but this sounds and feels like the air cleaner slapping the firewall. I am guessing one of the new mounts let go and the clutch chatter is being magnified during takeoff.

Before replacing the mounts last time I tried to jack the engine up in places to see if I could tell which one was bad. I couldn't. Anybody got a better way?

Save me some time- The vibration is at takeoff. Which mount is most likely the culprit?

Double bonus question- This is probably totally unrelated, but I also seem to have gotten air in the clutch hydraulics about the same time. I rebuilt the slave cylinder some time ago and it has performed flawlessly since. Just strange the problem seemed to arise at this time of this potential motor mount problem. Any chance they are related?

Too much text?

My engine rattles upon acceleration. Which is the most likely motor mount to be bad?

My first thought would be the front tranny mount.

Disconnect the dog bone and then see if you can rock the motor to the rear by hand, engine off, and see if the mount is broken.

Get a friend to help.

Gosh i feel stupid. When I tried checking for bad motor mounts before I did not disconnect the dogbone.

I will give it a try. Thanks, Steve.

BTW- When I replaced the motor and trans mounts I thought my dogbone would line up for reinstall but it did not. I had to force it. Could this aggravate/help damage motor or trans mounts?
