motor mount from hell
I hate rubber and think it only belongs on tires. The ONLY time I felt vibration was just when the starter was kicking the motor over. It eliminated wheel hop and the tires loved to break lose
. The mounts didn't hold up well with sold poly. I'm working making the 'pin' bigger and have less poly to fill. If that makes sense... It will make the the already stiff mounts, 50% more stiff.
I spent alot of time getting the motor running smooth before I went to poly. So... I didn't get any constant vibration.

I have tried something similar on another car I have, (not my Maxima) with
a manual transaxle. I cut up a heavy mountain bike inner tube, trimmed it
into a long strip that I glued and wrapped around the central motor mount
tube. I then used a large vice as an improvised press, and mashed the
glued and rolled rubber plug into the steel ring motor mount insert. This
more or less gave me a solid rubber MM. After I put them in the car, (there were two--like the Maxima) it was great! A nice solid feeling. I could blast through first and second and break the tires loose any time I slammed a gear. That lasted about two months, when I blew the 1st-2nd gear shaft bearing right out of the molded Aluminum pocket inside the trani case! I took it apart to see for myself. An automatic may fare better, but solid poly? In a manual-driven Maxima? I think you're asking for trouble with that application. MM's are designed to cushion trani components as you sequence through gear engagement. Take that ability away from the mounts, and other components, how ever robust, will fail prematurely. The poly would be a better solution in a suspension application IMHO.

.Good caution though
Hmmm... sarcastic humor?
In line with that thought, how about finding a really large nut or nuts to thread onto the outside of the sleeve? That would give the poly a nice hexagonal shape to grab onto and would probably take up a lot of space, thus making the mount a lot firmer with just a little poly between it and the outside case of the mount.

Yea the nuts on tube idea = good idea! Now I know this is a MM thread so just briefly...goon, what precautions did you take prior to installin poly? What did you do to smoothen up your engine? PM me if necessary.

I've done all the route cap, rotor, wires, plugs, timing correction, even a brand new distributer which was very $$$$ and did nothing. The last thing I did that fix it entirely was changing the injector plugs.
I have poly motor mounts as well. I like them, but some people don't. I can tell you this... if you don't like shaking then don't do it. My car shakes a lot more than it used to before the poly mounts, but then again I switched every single bushing over to poly except some random bushings........
