Is there any way to tell what kind of condition a non-running 240D engine is in? I am looking at picking up a 240D that is showing 119k miles which, based on the way the car looks, is probably accurate. The interior is in excellent condition, it has low mileage Michelin tires and the body is straight and looks good, although the paint is faded. Worst case I would put the interior in my 300D. Anyway, I wonder if there is a way to tell what kind of condition the engine is in. If I purchase it and bring it home should I remove the fuel tank, clean the fuel system, change the filters, change the oil/filter, adjust the valves and start of delivery, install a battery and try to crank it or should I just go ahead and pull the cylinder head and see what it looks like in there. The current owner said they purchased it not running and do not have a clue but he did say it would turn over. I am thinking - worst case - it could have been run hot in which case a rebuild is probably in order. Best case - adjust valves and get the fuel system back in order. If the engine needs rebuilding then it will become a parts car. The tranny fluid looks/smells good. It has been sitting for about a year now.
thanks
