RDX Motor Mount Guide

RDX Motor Mount Guide
I did all the mounts except the transmission mount, and wanted to give a quick write up.
The anchor brand motor mounts are garbage. The side mount had all sorts of things wrong with it. I would not recommend using it. It doesn't even appear to be hydraulic like they claim. I used a oreilly side motor mount, which seems ok. It comes with a life time warranty. I don't know if it's worth saving the money over OEM. Oreilly was same day delivery, so I went that route. Both the Oreilly and anchor side mount came with a detent nub in the wrong location, which i cut off.
BE CAREFUL with torque, the listed toque for the mounts aren't that high. I think it's like 50 ft/lb. The anchor mount stripped out with a 3/8 hand ratchet. I was definitely under 50 foot pounds. The O'Reilly mount also started to feel like it was giving out with 3/8 ratchet hand tightening.
I have attached the Acura Service Manual guide. Link To Service Manual for this job, I was unable to upload images due to error. https://imgur.com/a/9lSCbny
I would make changes on what the guide says.
1. I would remove the bottom toque rod first. ( I had issues with having the bottom torque mounts cross threading, either the previous person who changes this over torqued the bolts, or jacking up on the engine made the bolts cross thread. I had to buy a new mount plate and bolts)
2. before replacing the side mount, I had to loosen bolts over at the transmission mount to get it to line up, there is space to pry against the transmission to get the side mount lined up.
3. for the bottom torque rod, you will need to pry with a board against the engine and steering rack. doesn't take a lot of effort.
The bottom torque rod sucks. A brand New OEM rod has WAY too much movement. FYI this rod can look fine but still be bad. I plan to make a DIY polyurethane mount in the future.

the engine was bouncing around like crazy. you could really feel it when stopping and on acceleration. The stock torque mounts suck, and I will be making PE torque mounts when it gets warm.

Improved motor mount?
I am replacing my engine and thought I would do the mount at the same time. Did you make an improved design? Doesn’t sound like there are any good options based on your write up.

I had all mine replaced because 15 years old and I went with factory. Nobody makes upgraded or I would have gone with those. I've had trouble with parts store replacements before when doing power upgrades.
