I spotted a Euro 1982 280E in a local Pick & Pull a week ago. Someone had removed the oil cap from the engine, so I looked inside and saw a totally clean camtower. It looked brand new, so I am assuming at least the head was recently rebuilt. After removing the plugs and attempting to turn the engine, what should I look for on the outside for a clue of the block being rebuilt as well? (The engine is not very clean outside). Opinions?
