I just finished replacing the motor mounts on my GTS.......the car was built in late '91 so 23 years old.

the pic is of the removed Porsche mounts and new mounts sourced from Roger.

From left to right. Failed Anchor 2698, new Anchor and new Volvo mount.

Plus motor height before and after.

Sorry, a little late but my phnoe did not cooperate.

Malcolm did you need to do anything special to get the Volvo mounts to fit?

I went with Porsche mounts just because some people needed to bend things to get brackets to meet engine ribs, and move heatshields, or had issues with mount fingers touching other parts. I didn't want extra complication on a first time mounts job, but may be confident enough to go Volvo/Roger next time...

Roger. I'm guessing I need to add motor mounts to my list of parts? Also can someone link the tutorial?

jdinark,
You have supported your car from the incorrect lift points. That rail where the front pads of the lift are, is not structural and gets dented. The lift points are further outwards.

Adrian.....the install was nothing special following the great Dwayne write up and past experience (this was my 4th 928 MM project).

Install the mounts and xmember all loose, used the 'homemade' engine lift over 1", get the horizontal bolts in place and start the assembly/tightening process.

The engine is SMOOTH with the Volvo mounts.....well worth the effort to replace the collapsed Porsche mounts

I put the Anchor in my 86.5 but haven't driven it yet. They were "defective" but I "fixed" them.

Denny - what you did was turn a hydraulic into a solid. Remember that there is a large area at the top of the hydraulic mount which is just a void to allow the movement of the chamber with the water in it. So from your description you filled that void with solid rubber. When the weight of the engine is on the mount the section with the water in it has no where to go - liquids do not compress. This may cause undo pressure on the hydraulic chamber causing it to leak or even burst.
Look at the second picture in post #30.
Just my musings.

Roger, these were supposed to be solid mounts but were deemed defective. I think I got them from you and you offered a refund but only had expensive OEM mounts for an alternative because you discontinued the Anchor.

I decided to take the chance and make them solid like they were supposed to be in the first place.

Like I said, the car hasn't been driven since so I don't know how they'll feel. The engine has been run with them though and everything appears fine. I think they will be immensely better than the collapsed OEM mounts that they replaced.

I guess mine are collapsed as well. Volvo mounts ready for installation.

Thanks Malcolm. I'll try to be braver next install!

With you on smoothness though. Best bit is starting the engine - feels so remote!

This, this, a thousand times this.

It's a fairly straightforward project. There are a couple potential troubel spots, but Dwayne's writeup covers them nicely. There are a couple things different in the earlier cars, but they are pretty minor, and MrMerlin (Stan) has a thread on here about it.

And someone was asking for a link to the writeups. Here is Dwayne's homepage. All the stuff is there, just click on the project you want:

http://dwaynesgarage.norcal928.org/

Edit because my memory is going and I confused Bill Ball with MrMerlin.

I think maybe you guys who have done this job a few times forget what it's like to be a newbie. Seriously, I'm reading Dwayne's write-up right now, and...damn, this looks like an all-day, serious pain-in-the-*** job. Any time you have to build your own thing-a-ma-jig out of Home Depot odds and ends, it's not a "straightforward project." At least, not to me. I need to do this, but I'm freaking out a little lol.

Schocki, can you please post the height (bolt length excluded) of the three MM in your picture. The Volvo mounts (part no. 137 86 57 for the 700 and 900 series) I have in stock are 86mm high.

Yes the DIY engine support looks like a job by itself, or do what I did and just buy a used engine support bar on eBay! I'm struggling to think of other jobs I would use it for, so now I've done mounts/gasket it may be going back on eBay, and cost little/nothing in the end.

Dwayne's (and John Pirtle's) write-up is fantastic. Just follow it slowly and don't worry about trying to do in a day. You'll want to do lots of cleaning anyway, end up ordering replacement bolts and nuts, add projects on etc. For me the best thing about 928 ownership has been learning to work on cars and gaining confidence with every project. I'm still always on here asking "newbie" questions, but I also try to answer lots for others, and am far more competent than when I bought my first 928 in 2006. Oh and having the tools and experience has meant being able to do lots of jobs on the daily drivers in the family (most recently timing belt and water pump on my wife's Renault), so big savings there on shop costs.
