Has anybody replaced a set of motor mounts on a car with long tube headers? Specifically MBH?

I've got most of my tools locked up in storage during a move, and not sure I want to tackle this yet without them...especially if I have to pull my headers off.

Thank you for any assistance!

 

Damm if you have to remove the headers to do the job that's gotta Suck big time... Good luck though.

 

Yes, I have watched the entire process being done on my car.
My indy used a lift and propped a long pole under the engine. He lowered the lift slightly so the pole could take the weight of the engine off the chassis. He removed a few bits and pieces under the car, nothing major, and then using a crowbar he managed to pry the old mounts out and fit new ones in. This was the hardest/longest part of the job. In total it took one mechanic under 2 hours to complete the entire job and would have taken 1 1/2 hours if I had not been talking his ears off all the time. Total labour cost $ 90.00 and the mounts I bought direct from MB.

 

Not sure on the MBH but I was able to replace my mounts with EC LT. It was a little bit of a pain with fighting to find an angle to remove and install the mounts, but it can be done

 

Thanks brother...sounds like this is doable.

James, SPatykAMG- Thank you for the intel, gentlemen! Very glad to hear this.

I'll post how this goes with this particular header setup.

 

Doing this in your garage will be difficult. If you have access to a lift, then you can remove the subframe and leave the headers connected and lift the motor a few inches to take out the mounts.

 

Thanks. Which headers were you using when you did the mounts on an E55?

SPatykAMG- Did you loosen the steering rack? Thanks

 

No I left the rack in place just had to work the mount around till I found the right spot to slip it through.

 

Awesome. Did you use a jack under the pan? Thanks for the insight!

 

Yes I used a jack with a block of wood to distribute the weight.

 

Perfect. Thank you brother!

 

I finally did my motor mounts and trans mount. The job was very straightforward with the MBH headers already installed. If you didn't do them during the header install (or it's time again!), there really is no need to fret. I did this at the apartment with ramps and a jack/2x4.

A few notes for anyone tackling the job. I don't know if this applies to stock manifolds or other headers, but it did for these:

-Remove the 4 bolts/nuts (18mm) retaining the steering rack and plate. This will allow you to maneuver the rack around to provide more room to work, and get the old mounts out and new mounts in. I didn't touch the sway bar or remove the headers. I did loosen one of the lines from the rack (8mm) but can't recall if that really helped gain clearance or not.

-You can reach the passenger side top bolt (16mm) from the top side, between the 2nd and 3rd primaries, with some extensions and a swivel. The alternator is somewhat in the way when approaching this bolt from below. Thread the bolt back in from the bottom by hand, and then tighten it from up top. Please be careful of the starter or disco the battery.

-The top bolt on the driver side can be reached from below with a socket. I purchased the MB motor mount tool for this purpose, but it was easier and faster doing it this way.

-If you lift the motor high enough, you can squeeze the DS mount over the sway bar/rack, and out the pass side.

Hope this can helps. The headers provide some nice eye candy during the job.

 

thanks for the update/tips.. i have mbh headers as well and will follow your advice when i decide to replace motor/tranny mounts.
