So Ive be fascinated with the Mercedes V12 M120 engine. Mainly because it was used in the Pagani. Ive been messing with cars since I was 14 but never rebuilt an engine or anything. So yesterday I went to the junkyard and picked a M120 out of a 92 600SEL. It has 117,xxx miles on it. It was sold as "parts only". So basically a core. I paid $250 for it. My plan is to see if I can get it to run on a stand, controlled by a stand alone ECU (megasquirt most likely). Ive never done this before so I decided to go with one of the hardest options out there to learn from. So heres the engine. I brought it to the garage and went to my job. After work stopped by and decided to see what I bought. Took the sparkplugs out and poured some oil into the cylinders (engine was sitting on the shelf for 5 years). Then i turned it over by hand, and it turns over pretty easily. I want to simplify the engine by removing anything unnecessary to it, like the EGR valves and make it run by cable instead of wire throttle bodies. Any help and advice will be greatly appreciated.

Now to the pictures:






Plugs looks like ran a little rich


Some green crystals on two of them... i think antifreeze=blown head gasket
