W126 M103 motor mounts...
Just swapped in a set of Meyle and the passenger side has already collapsed after about a week.
Is it possible to use the V8 mounts on this car? What about trans mount?

I am sure... but for the $20 the thing cost, I have to mail it back and will probably end up losing money on the deal as I will have to have the new one shipped to me again.
In the archives here someone mentioned using '90-91 350SD/L mounts. Has anyone tried this recently? Granted the cost is more, the extra weight of the 603 Diesel should warrant heavier duty mounts (I hope). I need to also replace my trans mount... thoughts on just using the M103 version? The M116/7 mount differs from the 603 which differs from the M103. Great.

You might also consider looking into the M103 4Matic motor mounts from the W124. The are significantly stronger than the regular M103 mounts.

W124 ones do not work sadly.
Any input on the gasser or 350SDL mounts?

I usually have good luck with their parts also. The driver mount is still like new on the car, the passenger went flat within a few days.

Sounds like a defective part. Unless your trans mount is so shot that the engine is still moving around.

Obviously. But as said, it will cost me more to return it than it is worth.
SO, I am going dealer this time. But will 350SDL ones work or not? They have the proper bolt hole locations.

That is actually a common problem. The heat from the exhaust kills the mount in no time flat. Usually aftermarket mounts die quickest, but even OE will fail similarly. I'd recommend to fashion a heat shield for whichever mount you install.

w126 motor mounts
Quote:
I Replaced the mounts on my 1988 300sel last June 2016 The passenger side (right side) motor mount is completely collapsed and even though the mounts have a lifetime with FCP I have decided not to use Meyle again. The other motor mount option is made by FEBI. I will get a quote from the Classic Center tomorrow and probably pay up the money to get quality. I didn't even put 10k miles on the mounts. |

xaliscomex, best to buy genuine MB engine mounts, unless you prefer to replace the engine mounts on a routine basis.

OE seemed to be the only thing that lasts half decent on this car. OE were just put on around '05 when I acquired this thing in '07. I put OE on the car and they lasted a decent time. July '11 was around 276k on the car. Been flat for about 12-18 months. So it appears five years is all you will receive from motor mounts on a W126.024/5
Actually doing this again here, at 316k. Found one for $60.50 and one for $124.63, both new for OEM. I added an exhaust hanger to shim the bottom of the driver's side, seemed to help quite a bit. The mounts, when compressed, are about 0.5" too short from what I can tell and the downpipes will rest on that caster rod brace or the idler arm. Mine is on the idler arm as I dimpled the caster rod brace. Head is coming off to replace head gasket again, maybe I will ceramic coat the manifolds while off and wrap the downpipes to contain heat. At least my '90 model does not have precats just resonators. Meyle is garbage, I would not install anything from them on anything I own. They are in the same league as Uro. Febi is very close, but they are a repacker...so who knows what you will receive.
