Greetings,

Spent most of yesterday perusing the forums - great resource, thanks to all who contribute.

I'm in the market for a W124 wagon, and have a line on a couple 95 E320's. Based on what I've read here, the engine wiring harness and cylinder head gasket are two areas that seem to have the biggest hit to the pocketbook.

Question - plenty of info here on what to look for regarding these two problems, but I couldn't determine whether these are one-time fixes, or something that might need doing repeatedly if keeping the vehicle for many years.

Has the wiring harness been updated with new materials to prevent the cracking? Any change to the cylinder head gasket, or is the coolant/oil leak problem a design issue that can't be completely resolved with updated parts?

Thanks,

Bill
