Quick Cheap (possibly temporary) stiff motor mounts.
When I dropped my engine back in, I installed what I THOUGHT were stiffer motor mounts, but they ended up feeling just like OEM. I had wanted to just fill in the mounts with 3M Super Fast Urethane (Windo-Weld) like I did on my DSM, but because of the metal cup, I didn't have good access to the rubber, and you can't pump windo-weld through a hose, though I certainly tried. So I was laying under the car waiting for the oil to drain and staring at the mount when I had an idea. I went over and grabbed a scrap piece of urethane mudflap material (1/8"), folded it in half, and it fit nice and snug between the engine side of the mount and the metal box meant to contain it in case of a failure.
Sooo, I cut out 8 little squares, about 1.125"x2.5", and grabbed a tube of windo-weld. I made little PU sandwiches, ran a large thick bead of it down one of the long edges,and coated each side, then stuck the end with the bead on it into the top and bottom edges of the mounts. They were just tight enough that I had to give them a good push to make them go all the way in, and they squished just enough Urethane goo out that I could smooth it over the top. I sprayed it with a little water (it's moisture curing) and let it cure all day.
After it was good and cured I took it for a drive and I'm very pleased with the results. The whole car vibrates a little with the engine now, but not nearly as bad as the one with solid mounts I had a ride in. My shifter doesn't move at ALL now, which is a real accomplishment with my on/off 6-puck clutch.
After a couple hours of hammering on them a bit, they don't show any signs of seperating or moving. I've use the Urethane goo before and I don't expect it to let go anyway, it's tough stuff. I imagine if I got tired of them, I could probably work them out with a screwdriver, some elbow grease, and maybe a little torch action since windo-weld gets a little melty before it burns.
