Since when is it 'mm'?

I read the title and thought the dood was telling a tale of switching over to the metric system.

i was curious, if these were aftermarket volvo mounts how will thay stand up to the weight of the V8 engines?

docmirror

They are from a V8 Volvo. I think the engine is made by Yamaha, but it's prolly about the same weight as the 928 engine.

Shark_Week

V8 volvo? what model volvo is that doc?
if your talking bout the b36 that engine was from the 60's

my bad doc, i forgot about the xc90 and s80

Have you ever seen an ad for a used car that said: "It was always reliable - I never had to do anything to it"?

When I got my 91 S4, it was 10 years old and had 63k miles on the odo - it needed and received new motor mounts. Now it's 20 years old and 105k miles, and they are still holding up. I would expect them to fail again within the next 20k miles.

Nicole, don't say that. The mms are listening to you.

I can tell you the new Volvo mms even look better and of higher quality than the Ford mounts that we had used previously. They are packaged very nicely and it just looks like they are better. Then again, they could be made of used pinball machine parts but hey, who are we to know.

Also, I have found myself several times sitting at a stoplight wondering if the engine was running because I can't feel it anymore. Not like, it vibrates just a little. I literally cannot feel it idle.

They will if you put the Porsche ones back in it.

I am feeling very conflicted by this whole MM situation. Factory mounts are available, this is not an NLA situation-- but they are expensive and need replacing every 10-20 years. They work well and are designed for the application.

Solid Ford/Ancor mounts are also available, designed for a different application, but also a heavy longitudinally-mounted engine (but without torque tube). They have been used for a few years and I think folks were generally happy until the recent bad parts.

Now we're talking about Volvo mounts. No one seems willing to post the part# but I assume they are mounts for the B8444S 4.4L engine used in the xc90/S80. This is an aluminum 60-deg V8, probably lighter and mounted transversely. That is quite a different animal, mounting-wise.

They may be a perfect alternative, but all of my alarm bells are going off. We're talking about a product designed for a very different application with what, a week's testing? Hello??

We have solid rubber mounts in both of our cars, and I must say that I am not completely happy. No real signs of badness, just discomfort. The GT mounts seem fine, and behave as expected-- no vibration, minimal engine movement. The mounts that I recently fitted to the S4 don't seem right-- too bouncy. They are not the defective mounts as the engine height is OK, but they are not the same as the mounts that I purchased a year prior for the GT. And that's a problem with aftermarket parts-- you are never sure that anyone is watching the quality. (In fact I am pretty sure that no one is).

The Volvo mounts are a different issue. If they are OEM then hopefully someone is keeping an eye on the quality, but taking a part from one application to another deserves some serious engineering review. There are certainly folks here that can help with that, and maybe I've just missed it.

Like I said, I am feeling conflicted but I think what I will do for the S4 is swap the mounts for OEM.

Just my $0.02 ...

Jim, this is the fifth set I've installed with the first being a month ago. Now that is not a lot of time on the two 'test' cars. What I've seen on these mounts being cut open, and from Rog talking with Volvo and dealerships across the country, there have been no failures. The internals are much different than the Porsche OEM, stronger/thicker than what we've had in the past.

When comparing them to a factory mount, they are almost identical in dimensions, but stronger internally. Now they are hydraulic as opposed to solid, which are what I've installed in the past. The fords were a bit smaller and worked well, aside from this last batch.

Just my opinion, but I think the Volvo mount is a better product that what I've used before. I suppose time will tell as we get more miles on these. As for a part number, I'd have no idea since I don't sell them. As to if anyone is watching quality, yes, someone is but as has been noted in the past, accidents do happen and even Boeing misses in quality also.

On a side note, I'm very tempted to change mine over from the solid Fords, to these Volvo. The engine ride much smoother, but it also could be my bad TT.

Since I have no idea of what part number you guys are using I can not comment, but I will say that I do not stock a lot of different Volvo Motor Mounts for nothing.

There is a reason I have a bunch in stock and was willing to send Roger some, and that reason is they tend to fail.

You also have to understand that talking to a dealership about the reliability of a part does nothing, most of them never see a car after it is out of warranty.

Where are the failed mounts now?

jcorenman

Interesting info. Have the pictures of the internals been posted anywhere?

Thanks!!

Unfortunately the OEM mounts are $550 a pair, benchmarking Pelican.

I can change mounts in an afternoon.

At worst-case 2 years life, it'll be 2021 or so before the breakeven point.

I'll keep cycling through inexpensive replacement mounts.
