My power steering pump replacement has morphed, vacuum pump rebuild, water pump, front seal... I'm pretty torn down right now, most everything off the front of the engine, radiator out, etc.

My 1976 240D with about 112,000 miles was running great before I parked it a year ago, no symptoms. As part of the above, I thought I would remove the oil pan and clean it out; about 16oz. of coolant came out of the drain plug, then the oil.

I have gone back and read most of the threads about head gaskets, chasing down leaks, etc. I'm not a position to pressure test the system, I was going to just roll into replacing the gasket.

Before I do I wanted to ask all of you if I might be missing something?

Any thoughts about the job ahead of me are very much appreciated.

Thank you.
