modify drivers side stock motor mount to make solid

[Blazer406]

Anybody take and weld a small piece of steel between the two halves of the stock drivers side MM to keep from buying a high dollar one? I would leave the pass stock.... and just put a couple of metal straps between the two halves and weld it up....

Anything to save a $$

I figured if it didn't work you are out less than $20.

Thought about it with a small variation, but never did.
I wanted to weld the ends (only!) of 2 links of a chain (ghetto style ) as to maintain the stock compression of the rubber mount, yet have the limited "mount expansion" under tension of a solid mount under load.
Hard to explain, it is in my head ..............

I ended up with 2 H&R mounts and called it a day.

...maybe even a little better.....Lee Thompson and I both have a solid steel rod, flattened on both ends, that run from the back of the head down to the a-arm. Keeps the motor from twisting yet it's still sitting in flexable "bed"..........clear as mud?......maybe LeeO will chime in with more info.

I Like it!

Maybe I will be the first gunea pig.....

Drill a hole and put a 3/8" bolt. Cost >$1.
Just be sure it clears the frame bracket to mount thru bolt.

that's the easiest way to fix the old Chevy V8 mounts that like to come apart. just drill a 5/16" hole all the way thru the mount, then run a 3/8" drill thru one half of the mount and the rubber. tap the remaining 5/16" hole to 3/8" course thread, screw the proper length bolt in it and call it a day. a small dab of red loctite on the threads might not be a bad idea.

Warning... old thread....

Well ... I did it.... take a look....

Think it will work?

I did this to the front and back side of the drivers side motor mount.... Took about 20 minutes...

 

[charlief1]

Not to bad. I like the idea. Tell us how it works when you start using it.

Figured I'ld pull this back up. Did this little idea work?

Well, I have only put about 1000 miles on the car and one track trip with only 2 passes... and only with the stock turbo. Best pass was a 12.34 @ 113.47 with a 1.73 60' time. I really wasn't able to punish it very hard. I have my new tranny to install in the next couple weeks and a PT51 turbo to install before going back to the track..... hoping for some sub 11.50's in the heat and better 60' times. As I can make more track outings, I can put my motor mount to the test...... but so far.... so good.

Well at least it will limit movement without those stupid straps.

Here is my 2 fixes. Passenger side motor mount has over 3k miles on it. Also no roll cage in car.

 

[Pronto]

I currently have something similar to the turnbuckle thingie too. Do I see tabs welded to the motor mounts?

 

["Reaper"]

Yep worked out great.

Adding the 1/4 x2 angle iron sure with taking the twist out of the car. Really pickes the front end up pretty even.

 

[Blazer406]

The route I did should not transfer any vibrations from the engine into the car as bad as a true solid mount might....... but still keep the motor mount from coming apart as the engine rocks over on a hard launch.

My concern would be the U pieces will bend up when the mounts stretch. I was thinking the bolt through the mount but getting alittle longer bolt and using a hard rubber washer so it would have some to stretch b/f it holds it tight. Would have to check clearences for that idea though.
