Misaligned motor mount cover plate?

My 1983 240D needs new engine mounts and engine shock damper rubbers.
I have bought all these and am removing the bolts holding the mount to the frame and to the engine.

So far all bolt removal has been a breeze!

All bolts, even the passenger side inner engine mount bolt, were removed with a socket and extension, no problems.

On the driver's side, there's a steel plate that covers the inner bolt. It's a machine screw with a 6mm hole. Even though I have a good quality Allen wrench and Allen wrench sockets, the plate stops access to this last bolt.

I have been thinking about raising the engine just a bit, very slowly, with thick plywood on the oil pan, just enough to tap this plate out of the way and remove the last machine bolt.

Any other pointers?

I noticed that this plate was NOT mentioned in any of the DIY instructions from D*****G**** or iFixit.

Thanks to all who comment!

When replacing motor mounts, thinking about lifting the engine is a great thing to do. (I cannot think of a way to avoid it.)

Also think about disconnecting your accelerator linkage and fan shroud. You might also to think about the advantages of doing only one mount at a time.

That's the way I do it. The hardest part for me is getting the bolt lined up and started for the engine mount arm. Sometimes it is necessary to use a pry bar to move the engine a little.

i have had to lift the engine every time and have used a pry bar to lift even more on one side or the other.

X what # we are up to, you have to lift the engine a bit as mentioned.

I have seen these plates on both sides, one side or not at all. They were probably eliminated at some time when the mounts were replaced in the past. On the drivers side they are probably to help keep fuel off the rubber.

I don`t put them back on when iam doing mounts, this way I can see the rubber to see it`s condition. when fuel is spiilled, I just wash them off.

They sure are pricy, cost more than the mount is to protect. Probably not more if buying original MB mounts from the dealer.

Make sure you use lemforder or phoenix mounts, so you only need to do this once..

I changed Mine about 3 Weeks ago and I did jack up the Engine. What you need to do is take a look between the Engine/Bellhousing and the Fire Wall and see how much space you have.
If when you Jack up the Engine you run out of/use up that space after that you start jacking up the whole Car from the Oil Pan and that can dent the Oil Pan.
