So the rest of my "winterization" of my 1990 240 Sedan beater went well. Tie-rod ends...check. Stripped rear wheel stud...check (FYI, whoever says you have to remove the parking brake hardware, lies). Had the minor setback that one shoe separated from its backer but I was prepared.

Now the fun...I broke off spark plug with the rest of the insulator and center electrode in the head. I started to hammer the electrode into the cylinder and use an easy-out, but I chickened out. Having a local used car dealer do it (he specializes in flipping older eurocars) tomorrow. He assures me that he has done many of them and said all the right things...like vacuuming out the cylinder, accounting for all the missing pieces, chasing the threads after, etc. He even wants the broken pieces so he can tell when he has all the missing pieces.

Now, this was the first plug. What is my best bet on the other three? I assume PBlaster when hot... repeatedly. Is this like the brake line where tiny turn tighter before loosening is a good idea?
