Does anyone know what the actual height difference is between a new Porsche mount and one of the solid (non-hydraulic) mounts that are being used? I'm assuming that the new non-Porsche mounts are still taller than collapsed Porsche ones, even if no washers are used. I've seen people mention using washers to make up the difference in height, but how much is that difference?

heinrich

when they are flat it makes zero diff. Plus the stock ones do not sit at exactly the ame height, they are rubber with hydrauic fluid (probably water) ... so .... the anchor solids I've had on my S4 for 6 years are perfect.

I repent, Rog100...you make a good point. I keep forgetting. When I was a kid, "Made in Japan" was a joke. Today...well...cameras, cars, computers, you name it....quality that's almost unequalled. I own a Toyota...never a problem in 100,000 miles. Then came Made in China...at first it was bad....but with some massaging...it's getting much better. China's likely the sleeping giant that will eat us someday. You make a good point about India...IF the right people got involved in the manufacturing processes, they'll make a great product. However, in any nation just starting up in a new business, the quality tends to suffer until they get the mixture rignt and get momentum. I have a friend who owns the world's largest whitewater rafting supplies company. He's gone all over the world to get quality and price. He only got it when he sat down with a company and demanded strict standards...and kept rejecting until they got it right. They finally figured it out.

I frequently meet with fairly high level computing professionals and I'm amazed at where the Indians are technologically. You're right, the world's changing....however, keeping up is difficult. I'll concede that IF quality control is tight, the Indian motor mounts will be good. If not, they'll crumble in a few years.

No matter where they're made I would prefer solid mounts in my German 928. BTW, German Quality is nothing to be sneezed at. Only problem I see there is that the last Bosch parts I bought were actually made in Mexico, Brazil, and Bangladesh...anywhere but Germany. The parts appeared to be good, and I assume built to Bosch standards..but the cardboard boxes were obviously of less quality. In today's world, it's hard to tell what's best and what's not. If the part is of the quality of the boxes, I'm in trouble.

Keep truckin'

Hi Harvey,
I'm sorry I was on a rant.
But basically the point stands.
I have received my MM and some are of Indian manufacture and one is USA.
As an American I hate to admit but the Indian ones are better.
Pictures to follow.

I went along with Harvey's reasoning when I did my mounts. The originals lasted 15 years, and actually weren't bad. I did them as a WYAIT task. The Anchor idea was new, and still is, relatively speaking. Yes, there had been some premature failures on the Porsche mounts, but the numerator is quite small relative to large denominator. Mine are still like new. I understand how $18 could temp just about anyone. So, I don't blame you guys, but Harvey's logic is not erroneous.

Bill mine are still perfect after 6 years and 60k miles

78mm is a reported value for new 'Porsche' mounts: my 'Corteco' ( made in USA) mounts ... aka #2698HYD .... measured 76mm. I installed with 2mm spacers.
Any more would have been too much, for the right air tube is a very tight squeeze under the crossbar. Installation without the washers would have been fine.

Pictures of the two mounts side by side.
The cad plated (gold color) unit is made in India.
Notice how the Indians have gone to the trouble of adding the cad plate and also thread protection.
The unit from India has the extra pin. Why I do not know.
I will put the Indian units on the Cassirot 87 I just bought for a friend.

ROG100

Schocki,
Can you post a picture of one of the units you just bought please.
Thanks,
Roger

Schocki

Roger,
I will as soon as the arrive

BTW The Made in India mounts that I had in my hands at the autozone did not look like these on your pictures. They were all black and painted and looked exactly like the Made in USA that we used so far.

About mount height:
If they were both the same height, what would they be when compressed? Wouldn't that mesurement be entirely different for liquid-filled vs solid units?

ew928

Guess it's time to find somone with a press.
300lbs clamping force? 500lb plus for a fluid laden assembled motor?

A fluid will disperse pressure equally on all sides. That's what
I'm guessing occurs with the Hydraulic filling.
Vertical load in mount is partially dispersed to the side expansion
of the rubber.
Solid mount compressed will bulge less and differently than the
hydraulic one as the rubber molecules stretch and exert opposing
force to the bulging.

Did they know about silicone fluid back in the 70's.

Just hypothesizing.
The Oh-fficial Porsche mount makes the V8 lump very smooth.
Especially at the lower revs. Stalled the motor a few times on
clutch take-up as I can no longer feel any reaction from the motor.
Guess that's good for dentist's wives car.

Well this topic is now getting more interesting.
I decided to talk to Anchor Industries technical support.
My main reasoning being to track down the physical differences between the units.
1) Two pins v one pin.
2) One pin on the metal end v one pin on the rubber end.
3) Hydraulic v Solid.

Here's what I found out.
Anchor manufacture themselves and use a sub contractor (probably the Indian facility).
They are both solid and hydraulic.
How do you tell - shake them - the ones that are liquid filled are Hydraulic - duuuuur!
The pins are where it gets interesting.
I noticed that one of the units I just received has no pin on the metal end of the MM only the rubber end. We need a pin on the metal end for our cars.

RockAuto are now really confused as there are so many permeations based on one part number 2698.

I am waiting for Anchor to confirm that there are indeed different part numbers.

Update later

You guys kill me. All these wasted electrons on an $18 part that lasts 6+ years. Just go get the Anchor from Rock, use a single fender washer under it, grind the second nub if needed, and use nylock nuts.



Yes, the job is messy, no it's not hard to do if you have a few pry bars, there is excellent documentation, and the results are great.

Rog, see you Sat, can you pick me up from Roanoke airport near the fuel pumps? Is your compressor functioning?
