Good morning!

I have just begun to renew my 1988 190E 2.3 with 100,000 miles.My kid drove it last and unfortunately it overheated on him so it has been in the garage for some six months.

In removing the spark plug wires, the two rear ones broke off. Most of my Benz repair experiences have been with my W124 Station wagons, a 91 300TE and a 95 E320, so I've never really seen a self destructive spark plug arrangement like the one in this engine. From what I've read it looks like the best way to deal with it is to break the plug and be careful so as not to allow any dirt into the cylinder. I would appreciate any words of wisdom from this august site.

I've not found any evidence of head gasket failure but do plan on replacing the valve stem seals... and now wires as well.
