928 at last

Interesting. Never thought that one through, but excellent point. The new "elevation" of the motor back to stock, with the re-established rocking could cause some issues........
I'm just re&re ing the intake/fuel system now so it's past history, but others may want to check after a mount refresh.

So, my opinion is slightly different.

Don't play automotive engineer.

Buy the factory mounts.

They lasted 20 years.

How crappy can they be?



Oh yeah...I don't use silicone pan gaskets...either.

And I have tried them, more than once.

Your pan gasket is 20 years old.

How inferior can that be?

I can't afford to pay Greg Brown prices 8>)
So you alter nothing when you build a new engine?

Bull****, I just replaced a 3 year old set of factory mounts, they were collapsed. But they could have been NOS, who knows.

Yes and that is why I chose the Solid newer Ford MM's, the liquid filled MM was a flawed idea IMO w/ minimal benefits.

As for the Silicon Gaskets they are also newer technology over Cork, however greater care must be observed when installing.

GregBBRD

I alter lots of things...but you know that?

But I don't alter stuff that works really well from the factory. That doesn't make any sense, to me.

I can install a factory pan gasket and not have it even seep for 10 years. That's not a poor design, in my mind.

I tried the silicone pan gaskets...why not??? They might have been the best think since sliced bread!

Because the hardware had to be "finger tight" to not over torque the silicone gasket, the hardware fell out almost as fast as you could replace it. Let me see...add gas, check the oil, and tighten the pan hardware. Good to go for another 300 miles!

That's not a good thing, for my customers. They prefer to pay for a job once and be done with it. That's the "expensive" 928 service that we offer....that you can't afford.

Now...what....5-6 years later...people are talking about installing studs and using locknuts to help with this problem. That's sounds like a good idea....how many people need to redo their original silicone gasket to now make this modification? When that doesn't work, we'll come up with something else.....

Motor mounts...please!

There are a whole bunch of 928s still running around with the stock, original mounts still in them.

And there's a small group of people that have Ford hydraulic mounts that don't really fit...well...they almost fit. You only have to slightly modify things to make them fit. Oh yeah, throw away that stupid safety thing that Porsche made, in case the mount broke, but what does Porsche know?

Oh, by the way...those Ford hydraulic mounts failed after 2 years.

No big deal...we'll experiment with something else for a while...it's not our money?

Sound familiar? Think water pumps. The next "version" will be better! Yeah, we trashed dozens of engines with the first couple of versions....but the next version will definitely be better!

Oh yeah, I also don't use Porken's tensioners!

928 at last

Yours lasted twenty years??? Cool! can I get a set of factory mounts that last that long?

My money's on the solid Fords. I can spend my money and time looking after more critical items. Mind you, I'm one of those who would probably enjoy solid race mounts......

Seriously though, if you're not doing concours, and you want to drive the car without lying under it constantly, the best choice would logically be the longer-lived of the potential choices. The fact that they're by far the most cost-effective solution just makes the choice that much more obvious to me.

Awesome advice - thank you.

I have not installed any of the "Liquid" mounts, however:
Fact:
The Ford solid rubber mounts required NO modifications of anything, just bolt them in.
Fact:
The Ford Solid rubber mounts DO haves safety locking plates incase of a failure.

We all install what we are comfortable with, some chose the old standard (like motor oil) and others look to improve the breed.

I don't know about the MMs, I have not got there yet to buy a set, will probably buy the solid Ford ones, since they are so cheap. Did look at a friends Ford mounts on his 928 and they had open small cracks all the way around, Is that normal? He only changed them like 3 years ago.

About the pan gasket, I am using the factory one because I think the silicon ones are too thin and when you tighten down the nuts or bolts it squishes out from the sides, its not like anyone is gona go under the car and look at it but don't like the look and don't want silicon hanging out inside the block. There is nothing wrong with the factory ones and will probably last 10 years without any oil leaks.

jeff spahn

Wow, I really got things flying here didn't I? I was just asking about a low price I saw on some mounts but it seems to have opened up a real can here.

I gonne put in solid aluminum ones that will never fail. Might run a little rough but will never fail

GregBBRD

[QUOTE=davek9;7183718]That's exactly right. Hard to argue with that point of view.

We've all have reasons for what pieces we choose to use. I completely understand and support Roger trying to find products that save us all a buck. Roger may give me crap, but I think he understands why I do what I do. That's the beauty of this forum. We can discuss things and learn from each other.

My problem is that I run a shop and people bring their 928s to me to be fixed. They bring me 2,3,4 page lists of things that they have never been able to have fixed and we fix them. They drive their cars in, fly home, and come back weeks later to get them. They come from all over the country/world. Because of this, I have to use pieces that I know work. I can't create new problems. I need to fix problems. This is a far different thing than somebody swapping in pieces, in their garage, on their own time.

In all fairness, I have not installed a set of solid rubber mounts. I installed one set of the hydraulic Ford mounts and swore I'd not install another...that was not a good solution.

I'll get a set of these solid rubber mounts from Roger and see how they work.

A few weeks ago Sean and I dropped the x-member on my 86. It had a Ford solid in it that is at least 6 YO and it looked and measured like new. Also had the Porsche designed safety plate clasp in place.

If the Porsche mount were only ~$30 more, I'd use them, or if they were clearly superior to the Ford mount I'd use them. It seems from my experience that neither of these situations exist.

blown 87

I understand that.

Rob Edwards

I've got a set of solid mounts from Roger for the stroker already installed on the crossmember, so that'll be one local data point for Greg.
