Anchor motor mount longetivity

I'm not going to shoot down your argument, but rather I will offer a reasonable counter argument. The spec for the Porsche mounts is 78mm. I'll buy that. The anchor mounts are 75 and change. So even fresh out of the box, the Anchor mount does come up a little short. You've proved that point and I don't disagree. There are two other factors in the equation however. The first is price. Anchor mounts cost about $50, whereas Porsche mounts I think are pushing the $700 mark. Most people can forgive a lot of shortcomings when there is such a substantial difference in price. As for how much they compressed in a relatively short span of time, I have to ask how much does a hydraulic Porsche mount compress in the same span? Because they are rubber which does compress, is this compression you have here a normal result of things just "settling into place?" In order to really investigate this matter, someone would have to drop the money on a set of Porsche mounts and do the same comparison. But you're going to be hard pressed to convince someone that $700 is a good value when most are satisfied with $50.

Aatos,
My first question is - the Anchor MM is it solid or hydraulic?

Big question is how much settling should be expected in the Porsche Liquid Filled Mounts Vs. Rogers Solid Mounts?
JHowell also mentioned that the anchor mounts are 75 to start which is very close to what Rogers mounts are coming in at. Anyone pull one of Rogers mounts out to determine overall height?

Whoa . I just happened to have a camera handy when I replaced Anchors with Rog's mounts and wanted to share, I didn't intend to draw any conclusions.
I believe the oilpan-crossmember touching point around 66mm but I'm not sure. I also measured some well-worn but usable Porsche OE mounts a while back, and they were around 75mm, which could mean that they don't compress too much before total failure.
I wish I'd checked whether the Anchors were hydraylic or not when I installed them. They certainly don't slosh now, is there any way to check the type afterwards? I also noticed that part of the collapsing has happened on the top, the upper engine mount bracket has pushed in a 3mm deep groove on the orginally smooth top of the mount. That shouldn't happen be they hydraylic or solid.

A collapsed Porsche MM in its free state (not in the car under load) is 63mm.
In this state when under load the Porsche MM is metal to metal internally as there is no water left inside to act as a cushion.
I do not use Anchor any more and have not done so for about 18 months IIRC.
My MM (the one on the right in the first picture) is 75mm free height.
So compessed with the weight of the engine I would expect as much as 10mm and after use the MM would probably take a set at this size.
The key here is you still have a large amount of rubber acting as a cushion and absobing movement and vibration.
1st Picture is a collapsed Porsche MM and the second a used Solid MM.

Roger,
Whats your opinion on the Hydraulic VS. Solid aftermarket or "Anchor" mount?
Why do you choose solid over hydraulic? Curious what your reasoning is. I was going to go solid but then Dr. Bob convinced me to go hydraulic so i bought a pair at Auto Zone. I'm curious why you choose one over the other?
