It is time to replace or fix my motor mounts on a 2001 civic ex coupe. First of all I can only point out 4 mounts, but I keep seeing people saying we have 5? I have only seen 2 torque mounts ( front and rear), transmission mount which is on the passenger side, and the mount that is located on the driver side which is the main mount holding the engine. I have seen many diy on people making their own bushings so I decided to use window weld to fix my front and rear motor mounts by making a solid bushing. I was wondering if I can use window weld to fix my transmission mount as well or will it be too stiff? If stiffness is the case with the transmission mount can't I drill some holes into the window weld bushing to make it less stiff? Should I replace my driver side motor mount? I don't see diy or anyone really replacing this part, but then again I could be wrong since this mount main job is to hold the engine.
BTW pardon my grammar

We only have 4, as far as I know. Front (engine stopper) mount, driver side mount, tranny (passenger side) mount, and rear mount.

When I think of window weld, I think of the soft pliable stuff I used to seal my headlights.. there's DIY guide to making solid polyurethane mounts. As for drilling holes, I don't know if it'll work, because the stuff will be more brittle than rubber, so the chances of breakage are higher.. This is all off of speculation, mind you.

If I remember correctly, the driver side is a gel filled mount or something like that. I don't know if you'd have to replace it.

I agree the polyurethane is a better choice, but you will have to do all the mounts at the same time since that stuff hardens pretty quick after adding the activator.

I read somewhere oem rubber hardness level is about 50a. I know energy suspension sells some polyurethane with hardness ratings of 60a (for daily driver hard as tire thread), 80a(for even trade off between performance and vibration hard as cheap skateboard tires), and 94a(for race quality hard as hasport mounts). The 3m window weld is urethane and has a hardness level of 55a-60a that is already mixed in a tube giving me a much longer timeframe.

The reason I was thinking of using the window weld is because I wanted to do one motor mount at a time(a mechanic recommended I should only do one at a time). Then again I am working with 2 torque mounts and the transmission mount. If I can get those 3 mounts out at the same time safely then I would definately choose the polyurethane. Maybe I can use one jack to support the transmission and another supporting the oil pan. Do you think that is enough support while 3 mounts are out? Then again oem level is 50a and window weld is 55a-60a, so definately an upgrade plus an actually whole filled bushing. Thoughts?

Has anyone replaced the driver side mount? I think thats the most expensive one and I'm definately on a budget since I have to get this done along with my suspension. Got this car around 90k and I am almost at 160k and never touched any of my suspension components YIKES!

Did not know that about the windoweld..
It seemed like it'd stay really pliable even after using it

Yea they even have a database on how long it takes to harden up depending on the degrees, but everyone suggest atleast a day to put on and 2 days before driving. I just noticed the bushing for the transmission mount is actually a whole piece unlike the front and rear. Looks like filling it up should be done

windoweld is not suitable for a motor mount, maybe if yours is not broken you can pack some in to absorb vibration, but i doubt it would matter. the whole point of that stuff is to stay tacky and soft. it does not harden, in fact it is sold in a vented cardboard box. i have windoweld i used on various places like sealing leds and headlights, after a year its the same softness as when i put it on. i can pull it right off to fix something and its still soft and tacky.

not sure if this is the right thread to post this in but im having a problem with my engine mount the drivers side engine mount on a 02 honda ex one bolt is striped the bolt i am talking about is the one that goes to the engine if you look at the pic i uploaded it called e-6 bolt now just the bottom half is striped now my question is can i glue that in some how and what would you recommend me to glue it with or what the best way to fix my problem?????

No, you can't glue your bolts in place, maybe you could epoxy it in place with JB Weld, but that just a temporary fix not the proper way to repair a stripped thread.

To do it properly either have a heli-coil put in or re-tap it.

i replaced both my drivers side and front engine mount and i fixed the striped bolts now my engine is still shaking should i just replace the rear mounts also and are they are to replace????

the rear is much harder to replace, and usually its only the front that goes bad.
