Is it possible to change glow plugs without removing injector lines?
 
Yup...................
advisable, NO:o.

Boy does that tear up the back of your hands:rolleyes:

But the car does start now:D.

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? :D

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!

Nah, the hardest one is actually the one behind the oil filter housing.

I even made my own reamer.

Same here.

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

very good analogy:o.

Why didn't I think about the file.............

It MAY be possible but why bother
 
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.

Ditto. I changed mine without removing the lines right after I got it. WHAT A PITA!

Since then I've removed the lines for other reasons, and I can't imagine why anyone would want to mess with trying to change them without removing the lines. I can pull them off in about 5 minutes and they go back on just about as fast.

I still use the gear wrenches, but without the lines in the way I can do it much faster and without wasting time retrieving nuts or GPs I've dropped.

I'd bet $5 i can do it as fast or faster by removing the lines as anybody who doesn't remove the lines. And my hands don't get cut up in the process...

Including bleading the fuel system? I'll take that bet. :D

Yup, when putting the injector lines back on I fully tighten them at the pump, and only screw the nuts down finger-tight at the injectors.

Next I use my remote starter switch to crank the engine 2 or 3 times for 20-30 seconds at a time with a 20 or 30 second pause in between (to avoid overheating the starter) and that pushes all the air out and primes the lines.

When I start to see a little fuel bleeding past the nuts at the injectors I tighten them down snug with the wrench. Cycle the GPs and hit it again and it fires right up every time.

I've done this at least 3 or 4 times during the process of swapping injectors and prechambers when troubleshooting the problem with my old motor, then again when I put my injectors into the motor I swapped into my car.

Worked every time to prime the lines and get it running again in about 3-4 minutes.

So 5 minutes to pull the lines, 5 minutes to put them back on, and another 5 minutes to reprime them. I easily save more than that 15 minutes just by being able to get my hands in there to screw the GPs in and out and the 8mm nuts on and off. Not to mention no time wasted fishing out dropped 8mm nuts or GPs from between the IP and motor.

Well worth the time IMO...

I used a piece of old fuel line to get them out of the hole,and the same for the replacement. Gear wrench is the only way to go.
