Lots of engine vibration but previous owner replaced motor mounts?
Car: 1999 Civic Si (EM1)
The previous owner states they had the motor mounts replaced not too long ago, but there's still a lot of vibration going through the chassis.. Is there a chance they had some mounts overlooked?
Here's the diagram of motor mounts:
I'm thinking they replaced 2, 3 and 4 mounts.. but not 8 and 9.
Do you think 8 and 9 have a lot to do with vibration?
Thanks,
Div

Put your hand on the Intake Manifold and try to rock the engine back and forth. If it rocks easily or if there is a great deal of "play", something is loose or broken. Part 8 and 9 do help with vibrations, check to see if the insides of 8 and 9 are torn or broken. If so, replace and also purchase inserts, they do help. Also, check your rear mount, #7. Could be something as simple as loose bolt(s) (#17 and #13).
