Arggghhhhh simple tune up on a gasser and the plug boots are stuck on with gorilla glue!!!!!!!!!!!!!!!!!!!!

I thought I was supposed to turn them 45-90 degrees and they would pop right off, I cannot believe how stuck they are. Help me before I break the wires.

There is a special tool to remove the plug wires without damage, basically modified pliers. The wires are pulled off, turning them does nothing.

Pliers are not the issue, I can get enough grip, problem is that it is not releasing the plug. The rubber boot on the number 1 cylinder is already torn, I assume from a previous ham fisted operator such as myself.

Give us a clue on which car you're talking about.

Sorry, its a 300SEL, I have wide open access to the plugs and can get a good grip on the boot, I tried twisting it back and forth and jiggling while I was pulling on it.

Also I sprayed some penetrating lube down there as well.

I had the same issue with my 95 SL500. You need to get a good grip on the boot a give a quick tug. Once you get them off, make sure you put fresh Di-electic grease in the boot so next time they will just pull off.

Craftsman tool 9-47315

spark plug pliers $10

I used both pliers and hand.

MB tool #110 589 01 01 00 (Hazet #2771) is a 17mm double open-ended wrench that is placed UNDER the boot and then levered to lift the boot up from the spark plug.

I use a narrow-tip small visegrips to latch onto the metal boot flange. Plenty of safe leverage with this.

no, no tool, just work them off nice like, they'll come off with patience...a little twist here and there should work nicely...

LOL, not this particular set.

Well, great success! I did buy a set of pliers the did the job, however one of the inner plastic tubes actually broke and forced me to "dig: it out. Took a 20 minute job and turned it into and hour and an extra trip to the auto parts store.

The good news is that the car runs much much better now. I put new wires and platinum plugs in. I cleaned the points as well but am so happy with the result gonna go ahead and get a new distributor and rotor as well. Yes I am that cheap.

Also decided to do all the fluids as well. If anyone sees this, I need to know what ATF fluid to use, I don't have a manual for this car.

Thanks for all the advice!

well, that's good/bad concerning the wires but putting platinum plugs in was a very poor move...very bad idea....i would remove those pieces of crap immediately and put the new coppers in myself....

Yes, you want to ditch the platinum plugs post-haste. M103 motors hate platinum plugs, ask me how I know......


--- Points?? ----

Whats the story with the platinum plugs? They were the only BOSCH plugs the store had, I actually did ask for the copper plus but they didn't have any.
