Icon5 Just installed motor mount inserts, vibrates like a mofo

I just installed new front and rear motor mounts and put energy motor mount inserts into them, since my old ones were so wore out and the motor was rocking around so much before I thought this would just stiffen it up. It did that but now the interior vibrates so much at idle. My question is does anyone know from experience if they will "wear in" and start vibrating less?

Re: Just installed motor mount inserts, vibrates like a mofo

if your old mounts were so worn out, then you'll def notice a major difference with new mounts, PLUS inserts!


when i first installed my inserts (front and rear), i did notice a slight increase in vib's, but not to the point of being annoying or a PITA. and my car is a DD as well.
idk if i just got used to the vib's, or if they did slightly wear in, but now i don't even notice a difference. the only time i do notice the difference is when the AC is on.

Re: Just installed motor mount inserts, vibrates like a mofo

I recently have upgraded to new motor mounts and ES inserts and they work great. At first I was kinda annoyed but youll get used to it. It especially vibrates when you have a/c on. But I dont use that anyway. I love the way the cars drives now though, shifting is wayy smoother and launching... forget about about it lol. This is probably one of the best cheap mods out there for any person that wants to maximize potential of their motor so just deal with it for now and youll get used to it.

I've got steel engine mounts...causes some vibration...it may take some time to get use to the slight vibrations caused by the inserts.

Re: Just installed motor mount inserts, vibrates like a mofo

front one was cake. took like 10 minutes tops.

rear one was a bittttttttttttttttttchhhhhh, cuz you basically gotta do it blind, by hand, and i couldn't even get the entire mount bracket outta teh car so i had to slide the inserts into the mount w/ that bitch still in there... not fun!!!

Re: Just installed motor mount inserts, vibrates like a mofo

I removed the rear mount totally because it was to be replaced with the new one anyway, I would rather do 4 of the front ones than one more rear.

I went under my car earlier looking for loose bolts that might be causing even more vibrating than normal and I found that I am missing the beam that runs parallel to the exhaust (pic attached). Would that cause excessive vibration?

Re: Just installed motor mount inserts, vibrates like a mofo

Hmmm maybe the vib's are just from my car idling like crap, don't really know why either. I have replaced: fuel pump, fuel pressure regulator, injectors, coil, cap, rotor, plugs, wires, TPS in the past week and have adjusted the TPS and made sure the MAP was working within range. Idle is a little jumpy, has some hesitation from idle to about 2,000 RPM's, seems to have pretty good power after that. My next thing is the ECU. Mine has a chipped P06 so they added Vtech and added a rom chip with who knows what on it so I ordered up a JDM P13, hopefully it will be the answer.

For the most part it will be at the right idle but every about 15 seconds or so it will dip way down, seems to do it more so when cold and also doesnt just fire up when I turn the key when its cold, I will have to crank it over for a second, stop, crank it again and it will start.

Re: Just installed motor mount inserts, vibrates like a mofo

yep.yep.yep...i just installed motor mounts too (fron and rear), they were the energy suspension ones...and yes the car does vibrate like a mofo because your engine cant move back and forward like it used to on oem mounts...but just think of that extra torque you can put through to the wheels....i have not still got used to the vibration...but the drive is awesome....best way to put front engine mount on is to drop the cradle out completley.

you gotta be KIDDING me!!

you'd rather take the front bumper off, lower splash shield, toe hooks, radius rods, then finally the subframe....

rather than 4 17mm bolts to take the mount bracket off????



sounds like you did entirely too much work, hahaha

Re: Just installed motor mount inserts, vibrates like a mofo

I think the Motor mount inserts might just vibrate too much for me because I am in an automatic :( (vibrates so bad in D) in the next couple days I think I will pull them out and see what she feels like. If it helps I will just set the inserts to the side till I do my 5 speed swap.
