Anyone ever see this happen to a motor mount?

Got me curious, so took a look at some motor mounts I had in a box - the 3 orange are '87 mfg date and were off Turbo S cars. The updated two are OE replacements, '93 and '94 mfg dates.
Two of the orange ones are collapsed below the 65mm factory spec (70mm new, 65 or below requires replacement per FSM). Third one was about 66mm, so close to junk too. One for sure show signs of leaking fluid. Can hear fluid moving when you shake them.
Cant hear anything when shaking the updated mounts, but both of those still measure 70mm height, even though they are well used.
Whether the updated/968 OE mounts are liquid filled or not (I now doubt my previous posts enough that I am not willing to risk wrecking one by sticking a nail thru it to check), spend the extra money vs. the fake ones. The new factory mounts will last for years, possibly the life of the car.

I will say that the PS hardline is almost touching the oil sending unit rubber wire caps ... So I am guessing its not were its supposed to be
The original motor mount designs were fluid filled, and they would collapse/leak. Used to be one of the chronic premature failures of the 944 - water pumps, timing belts and motor mounts. Porsche released several updated parts over the years to correct the problem, finally went to a basically solid rubber mount w/ the 968 mounts. The mounts on the late 944s were better, but 968 mounts pretty much eliminated any premature failure problems of the early versions.
LOL thanks Bud. And, based on how much time it spent in the garage, it really was

Check out the mounts from Rein Automotive, as far as i could tell they are OEM with the Porsche markings ground off.
Rein mount, hard to tell but this area has been ground down.

Ya my car has a leaning for the dramatic
I must have nicked an artery
Thanks Jon I saw your post way back when, on those and was thinking of taking a chance and then saw that the stock ones can be gotten of like 260 for the pair and decided to just go with the Porsche ones ( being that I am a chicken **** and do ever want to do this again )
Best regards

i did my motor mounts in the last two months. where did you get the real porsche mounts for $260 a pair? i think i paid $385 for both of them. i first ordered the Rein mounts and they were not porsche part numbers and did not have the P on them. so i sent them back for the real ones.
this is confusing because the porsche mounts say made in germany. rein makes there stuff in czech republic. i think crazy edie got lucky or the supplier he got them from had a different batch. i tried the same thing and it didn't work out for me...

have exact same problem now on the same side.
i appears to happen from excessive back and fro movement from softened gearbox mounts,
and up and down twist of engine during acceleration and deceleration which allows the whole engine/torque tube/gearbox to twist more than it should ,and with age the rubber gets more
rigid,it snaps .pulls the silicon bag inside and causes it to rupture.
Seen the same on my 968 triptronic as well.
Best is to go semi or solid g.box mount.For the 968 polyurethene windscreen selant is the answer.
The complete assembly will be more secure and mountings will have much longer life.

I was happy, not to have to pay 500 a pair, as that's what seemed to be the earlier cost? Not lucky, just can remember things very well anymore
