I will have to contact rein because all it says in thier parts catalog http://www.crpindustries.com/rein/pr...talog_2009.pdf
(bottom of page 122) is holder with rubber mount. I do know one thing, I have had my car since it was born and I have almost 85k on the car and this is the first time I have had to replace the mount.
The only other thing I have ever had to do was replace the thermostat at 76k. Well other than normal maintenance I feel I have been pretty lucky.
As soon as I find anything out about the mount I will post it.

My 03 is vibrating really bad at idle but can't see any leakage around the mounts. Would this be a symptom they are going bad?

The above posts are about the mount MINI Started using in Dec 2003. Check your build date, found in drivers door, you could have a bad upper motor or lower motor mount. Let us know the build date, miles and type of MINI and we can help you better.

Thanks for the details. You have the early mount and the TSW one here will not work for you. We have replaced a few of the early ones too and your's might need to be replaced too. If you could email me or post some pics of the mount here I think we might be able to tell for sure.

I noticed an "oil leak" tonight when I pulled into my garage as there were a few drips of fluid on the ground. It was very black and as I had just checked my oil the other day I knew it was nowhere near this color. Looked under the hood and sure enough, the mount on the passenger side had spewed hydrolic fluid all over the area. Luckily mine is an '06 so still under warranty otherwise I'd be all over the TSW mount...

Mine is still under warranty and I already replaced mine once myself because I did not want to go through the pain of taking it to the dealer. I wish the TSW mount would have been out when I needed to replace mine. I plan to install the TSW mount. If I was you, I would not waste my time on another OEM mount that will just leak again (even though it is relatively free).

My mount started leaking at 30k. I replaced it with the TSW urethane fix, and for my tastes am very happy. At idle there is more vibration and I have had a few passengers say the car is louder in-general. But shifts feel more succinct, and the entire drive-train feels less ‘mushy’. And its not going to leak all over the place at an undetermined time.


+1 for the tsw replacement

When mine died at 15K on my '06, I had the warranty replacement done and then added the TSW helper damper. The engine moves significantly less with this damper and hopefully it will last much longer than the original.

I guess the TSW mount will be the next step when this one does finally start bleeding.

Ditto.. same story. My 06 had to have its replaced too at 15k and have the TSW bamper. I now have 120k on it and have had no problems

Guess I have been pretty lucky, replaced the original in my '05 S at about 70K miles. Just notices it is leaking again at 135K, will do the TSW mount this time.

Just a note to you northern climate folks like me...do your homework. I was at one time the first person in line to procure the TSW mount but I'm staying on the sidelines (for now).

This is a quote from info provided by TSW on the new replacement mounts -- "We expect this rubber [polyurethane] to survive in ambient temperatures from about 0F up to about 120F. To be confident that the parts would do well below temperatures of 0F, the parts would have to be tested that cold."

I'm not faulting TSW at all; the vast majority of their potential customer base are located in regions that don't have to deal with such cold temps. And in reality, it may take time for the poly to lose its pliability when subjected to cold, and the loss of flex may just mean extra vibration and not greater susceptibility to cracking. But if your MINI spends extended periods of time sitting in sub-zero ambient temperatures, suggest you keep this in mind.

It seems it is not just the 05 and 06 HMM that go, my 07 cabrio HMM appears to have gone. Will be taking it to the dealer as soon as I can get it there. With a bad HMM will it cause the car to pull in the direction of the bad mount?

Put one on the R50 in Dec, when it was about 5F in the heated garage, well below 0 outside...didn't have any cracking issues but it took until about two weeks ago when we saw our first 40F before the first 20min of the ride wasn't teeth jarring.

I think it boils down to the nature of the material, and the fact that 90% of the country spends 90% of the year above 20F, so it's largely a non issue, and one that's difficult to test in TX. My experience with it wasn't so much fear of part failure, but rather a rough ride until the engine bay got some heat in it.

That's my .02.

That's really valuable feedback Drew; much appreciated.

In the 5 months since I made my cautionary post I haven't heard of any cold weather failures...just cold weather NVH analogous to your experience.

Ergo, I might just have to relent and spring for one of these sometime soon, before my second OEM mount baptizes the engine bay again.

that sounds more like a control arm bushing. granted the engine does move a little bit more with a bad mount, but i dont think its moving enough to effect your suspension.

(then again, im not an expert)

I've got it too... '05 MCS with about 53K miles.

So the blackish fluid is NOT engine oil, but rather hydraulic fluid? I checked my engine oil and it seemed a bit low, but I don't usually have ANY leaky spots under the car, so it might just be beause I'm about 3K beyond my usual change spot (ahem!)...

Thanks...

The older your oil gets the easier it is for the engine to burn it. Don't know exactly why, but that seems to be the case. That hydraulic oil is a bugger to clean off the frame rail.

Isopropyl Alcohol, and if you have any smooth areas to be cleaned a Magic Eraser can be useful as well.

Yep - read that earlier in the thread. Mine actually wipes right off, since it hasn't had tome to "bake" on. It's still wet and fluid - looks like I'm dumping ALL mine at once rather than a slow drip that has time to dry out...

Matt, check the front of your engine block above the oil pan for oily dirt deposits. 50-60K is where many run afoul of the worn crank sensor O-ring seal with associated oil blow-by, which doesn't drip but collects as gunk on the block. It could be the source of your low oil level (I speak from experience here).

Now back to your regularly scheduled motor mount thread.

Will do - good to know. Thanks!

I think mine is going, but I think worse I may have completely broken the bottom one (if there is one)...

06 S - 49,xxx miles (49,666 when I noticed this problem.. :hmm I had driven it 90 miles with no feelings out of the ordinary to me, then at a stop light I heard a tick suddenly, and when i went to take off I could feel the whiplash in the drivetrain, and again when I stuck the clutch in to shift to 2nd. Obviously I parked it ASAP and borrowed a friends extra vehicle to get home. I did pop the hood and to my horror i could take the motor and literly rock it back and forth (front to back) with practically NO pressure nearly 2 inches. I see dried on fluid on the passenger side mount, is it possible that the mount was bad when I got it, didn't realize the warning signs because I didn't know what it was like with a good mount and that caused the bottom one to go?!

Better question, there is a lower mount, right?

I found this online: http://www.namotorsports.net/detail....0102/xref/base And am tempted to load the mini up haul it home and see if I can replace it myself... I don't have a mini dealer near here, and the BMW dealership just changed hands so I don't know if I trust them with it.

any thoughts?

just looked where it is and where goes, confident I can replace it, and definitely think I'll toss one of those trick billet ones on if this is the problem.. I have to assume the bushing is gone completely the way it acts.. now the question, don't cringe, what kind of damage will I do driving it home 90 miles at 55mph?

Yes if you have the dried fluid on the pass side you need a new pass mount. There is also the poly engine mount, "soon to be back in stock".

For the lower mount we stock the BSH mount, but if your looking for something cheaper you can get the OEM mount and the powerflex bushing. It won't be as hard as the BSH mount.
