Idle vibrations

[Jim Lepage]

I have some vibration at idle (M50 at 600rpm). Could it be worn motor mounts ? It's also shaking while I release the clutch to start in 1st.

My tranny mounts are brand new by the way.

There's a lot of factors that could play a roll in transferring vibration to the chassis.

What motor mounts? How is your exhaust mounted to the chassis? The motor is running fine correct?

-I bought the car swapped but the motor mounts look like e28 ones.

-The exhaust is mounted with the bracket on the tranny and rubber mounts rear.

-Yes the motor is running fine.

What do you have for a flywheel. Mine vibrates a lill I think its from having an 8lb flywheel.

I don't know what I have but it didn't do that since a lot of time. It started to vibrate on the highway at about 65/70 mph so I discovered that one of my tranny mounts were worn. I changed the 2 tranny mounts (took OEM ones) and now that's almost gone but it's vibrate at idle. Tomorrow I'll check my motor mounts to see if they're in good shape.
