Short answer: yes!
But again i have tiny hands, and can remove the 3rd cylinder glow plug by sliding my entire arm under the injector lines (i did it yesterday).
You need however to remove all the vaccum manifolds and all the stuff perched on top of the valve cover.

The only thing I removed was the throttle linkage to the firewall
and the vacuum line to the tranny.

I agree with Jack - do not remove anything other than the linkage - and my hands are big enough that I can palm a basketball.

A ratcheting combination wrench (ie: Gearwrench) will make the job much easier.

A gear wrench and a file to take off the sharp edges of those sadistic clamps are the tool needed to do the job with the lines in place.

If I can change all 5 with only my bear claws and 8/12mm gear wrenches, anyone can.

But your hand looks like you got in a fight with a cat when you are done doesn't it?

GUYS i Change my glow plug's, with 2 long wrench's and a magnet, after that all you need is skill and mechanic's hands. no need to remove the the fuel injectors lines....... or you will need to bleed the system after that.

take your time, put some music on and open a beer AND then you will be able to pull through!

I don't remove anything except the glow plugs themselves. Then again, I have little hands.

While it may be possible to remove the glow plugs without removing the injector lines it is MUCH easier if you remove the lines first. I have seen this done at the tech session in Detroit last winter on a 300D and have since done this myself on my 300SD and in both cases about 45 sec of cranking was all that was necessary to fire it right up - no complicated bleeding required.
