Febi might have to deal with that with all of his new found HP under the hood

When I pulled mine apart there was a large washer under the lower nut on the drivers mount. It looks like it pulled through at one point.

The next time I have it apart I'm going to weld in the TMS braces.

The lower ones in this pic which weld into the motor mount area.

Which of these mounts will bolt in without shims and minimal or no grinding of tabs?

The green boys. Bear in mind you will feel more NVH as our 4 pots aren't silky smooth like the 6 pots. I have them and like them and noticed the increase in NVH. Doesn't bother me but I have anal friends and picky passengers who comment on them after they notice the vibrations at idle.

I'm using the M40B18 mounts?? PN 11 81 1 129 286
They look more like the E21 mounts then the E28 mounts..

These are what I'm using for my M42... Been using them using I threw out my old M40B18 and replaced it with the E36 M42B18 from an 95 318ti 4 years ago...

Did you have to use any shims or anything like that? They certainly are cheap at only $10 a piece. I also like that they're from a 4 pot, I'm kinda concerned about the extra vibrations.

only used a couple of shims on the right mount. none on the left mount. Vibration... been using these since day one and been thru more than 10 trackdays and a few auto-X. I don't have a comparison on the vibration as I haven't tried any other mounts but it have been good, so far.

So are there any mounts, aside from the $100 a side original M42 mounts that don't require shimming?

I used late model E28 mounts(green).
Easy install, no shimming,
glass beaded my motor mount arms while I had them off.

Little more vibs in the car not bad at all. Firms up shifts greatly.

The pass side top nut can be tricky. I did it from under the car using a long handled swivle headed rachet.

Can you show me a pic of what you used? I'm not quite sure what you're describing. I just tried getting to that top nut, I can't get a stubby or regular wrench on it, sockets are obviously hopeless, and it's pissing me off! :mad:

Would this do it?

Wow.. it's funny when I get a PM in here because I haven't looked at the forum in months. I wanted to stick around after I got rid of my car but we had all that downtime and I never got back into it.

For the tools, that wrench should work. I used something similar to this:

the green mounts shown above will be the more prefered versions as they're easier to modify for fitment. The price is still far less than the M42 mounts. It's odd that everyone besides Autohaus shows a different mount since the pics I stole came from WorldPac which is where most web based companies get their parts.

Regardless, the green mounts have been proven to work several times so they're the best option when in doubt.

I swapped back to good condition stock mounts as I was about to sell my Sedan. NVH did increase and decrease when I had the mounts in and went back to stock for those of you who daily drive and have wives/gfs or are concerned about such matters.

FWIW - A reputable BMWCCA club racer stated the factory m42 mount is STRONGER than the green jobbies. Yes they do cost more, but they are worth it. He sheared the e28 mounts and actually uses the hydraulic mounts in his e36 race car.

Taking them off - I don't remember using any super tools but I'll check again when I get home.

As a tip, you can cut off part of the long threaded shaft to avoid excessive protrusion.

Thanks for the answers guys, I cannot believe you were able to get a socket in there! ....I'll have to go look at it again, but there's an inch at the most between the nut and the stock manifold, I don't get it! :confused: FWIW, I've got some nice big yellow urethane mounts that are itching to get in there.

*edit* NEVERMIND I'm a moron. I can get a socket in no problem with a swivel and extensions from the top, in front of that manifold pipe. Duh. Thanks guys.

Haha. I actually went and combined my two 3/8 extensions 17mm small socket and ratchet in a bid to figure out my wizardry

only to see you figured it out :rolleyes:

Gotta love the simple stumps as they are easier solved than the MAJOR ones and often serve as a good laugh

mgold · « **Reply #44 on:** April 19, 2007, 12:17:59 AM »

has anyone tried the Ireland Engineering urethane mount? At $45 each, they're more than the E28 mount but possibly better.
