I believe Devek still has the factory '83 - '95 mounts for $195 each.

I did extensive research on this issue when I was going to replace the MM on my 81 auto that is sadly departed. I wanted to get the newer style, because they were cheaper, and pretty much smoother. I updated the cross member so that the later mounts would work. But thats not the point: I used the "ford mounts"

They aren't really a FOMOCO product, just in case anyone was mis-informed. They are an aftermarket supplier for ford, called "Anchor" but these "Solid" and "hydro" (Fluid filled) mounts are made by a company called CORTECO. I called this company and they do offer this mount in both solid and fluid filled. Jim bailey suggested to me that the solid mounts would need the shock dampening of the original car's "mini-shocks" and that may very well be true.

You can get these mounts for between 25 aqnd 25 dollars each from many many places, and I think its a 26XX part number. The mounts from Porsche are 250? 225? Even 175 if you can get them within a certain time frame at that price?

Porsche is not god. They make don't make these parts in thier special "german made" factory. They source it out to a regular districutor that probably makes rubber things for many companies, including Lancia. Skoda, WHATEVER. Because those other companies get the similar-tolerance parts, are we going to say that our parts were clouded by inferior automotive brands? Crazy?

So is buying a part for 8 times more then you need to because it says it was made by Porsche (as I said above, it wasn't).

The Corteco mount is essentially the same, if not a bit shorter. Get a big heavy duty washer (not multiple) and make sure its at the correct height./ These ARE WEAR ITEMS. They collapse from heat. They need to be replaced about every 50k, or probably every few years if you want a smooth car.

Yes, our cars were a true porsche. Hand built in a large part. Its the idea. The greater picture that makes the 928 what it is. Engine, Transmission, body, Look. The parts are simply the details that make up the whole.

We use Zimmerman rotors, portfield brake rotors, securite glass. Why not corteco motor mounts?

$195 or $24? hmmm... tough choice..

MikeN

Wasn't for me........I did the $195 route and never looked back, no questions, no big washers, just went on down the road with a silky smooth engine.........to each his own.......

Boy, this has become quite the religious war I'm going to be replacing mine this spring when I'll have full access to a lift. I'm going to use the Corteco mounts. I've read enough positive and negative experiences in the archives about both these and the OEMs that it seems like a reasonable choice. If they don't last, maybe I'll try the OEM mounts later, but I won't be nearly as upset as I would be if I tried the OEM mounts now and they didn't last.

-Gary

BTW. Are the OEM mounts exclusive to the 928?

jon928se

Not a religious war - Brendan speaks a lot of sense it's a part produced to mass production standards but not produced in mass production numbers hence the price. It will be of a simlar quality to other motor mounts. The reason they fail earlier than one might expect is probably heat cycling - I guess if you could find a similar mount from a real mass production car with similar underbonnet temps/ engine weight etc it would last longer than the Porsche mount.

For me it's a no brainer - $25 dollars versus $200 - I can put new ones in every year for eight years (likely life of the Porsche mount) and still be in the money.

Its the remaining thing on my list for the Engine rebuild in the spring. anyone know if Corteco will ship to the UK ? anyone know the Corteco partNumber ?

I'm planning on putting in the set of the fluid Anchor mounts (i've had on the shelf for 8 months) in this winter. Along with the new rod bearings!

So the GT will have the following non-oem parts:

Nology wire
RRFPR
"Ford" mounts


Now the track car is a litte different story.
Has a few non-oem parts!

MikeN

Hmmmmm.......EVERYONE I have ever talked to, myself included, would not want to replace another motor mount in a 928 for 10 years after doing it once........let along eight times in eight years.........that's exactly why I spent the money and got the factory mounts........sure you can get away with it on some things.........but this task takes way too much effort and time to experiment........IMHO.......

PorKen

Does anyone make a polyurethane mount for the early or late mount?

bcdavis

Now you're talking...

John Veninger

I'll let people know if I have to change out the mounts before 10 years. The orginial ones in the 90 were shot two years ago w/ 30K miles.
If these fail in less than 5 I'll put in porsche ones the next time. If they last past 5 then I'll be happy.

Thanks Martin Dunks, for the pics: I've read considerable qualitative commentary about failing/failed motor mounts - these pics are close to quanitative, and convincing enough to add this job to the winter list.
A "Ford" mount is available (north of the border) from Car Quest as P/N 31-3679HY for ~$55 cdn(~12% oem cost). It is 79mm high, ~72mm at the base, and has locating pins - application '97 ranger 2.3l, etc.
Does this sound to be the correct mount? - spacer of x mm req'd?
BTW, age and heat must be the controlling factors in failure: the '88 had the cold start vibration, etc from purchase this spring at 51KKm (~31K miles).

John Veninger

You want the Anchor 2698

Some of the applications of the 2698 mount include:
1986-1996 Ford F350 4.9L V-6
1997 Ford Ranger 2.3L L-4
1997 Mazda B2300 2.3L L-4 (same truck as the Ranger)

The 2696 mount is listed for the Ford Tempo 2.3L.

Someone send me their old Porsche motor mounts and I will refill them with urethane and give them to a fellow 928 owner in need for indepentant testing.

I just don't see any problem with this process and it would be cheaper, stonger and fit better than the Anchor mount.

Can't get any better than that!

Randy V

I used the Anchor mounts, but I very carefully stenciled onto them the word P-O-R-S-C-H-E.

Freakin' car now rides like a dream - just like Porsche designed it to.

Don't take chances with your parts - if it doesn't say Porsche on it, it ain't the same!
