porsche 911 engine - teardown 1

ok, i had to start to take a peek, what went wrong with mister aarnio´s engine re-build. (it took 4 years to get it back)
First, i havent seen any other engine with so many nuts, washers etc in the intake ports, plus so much crap...huh.
i took off 3 heads and discovered lots of ugly looking foam in one cylinder, and some sand/sugar looking chrystals in one cylinder, and whats pretty strange, there was also missing exhaust studs...wtf? ...and the main reason is still unclear, why the engine is freezed. :-)
