MBenz, yes I am replacing the wrecked 300SD. Actually, the settlement worked out great. I received more than the cash value of my SD, and I got to keep it. Over the next year or two I will throw together some money and fix it. But until then I need a car to drive, and the 1991 300D is something I have dreamed of for a while.
I can deal with replacing a head gasket, but a cracked head sounds expensive. This engine does have a turbo. Are head problems common with these engines, or are they caused by overheating or something?
