Can same one tell me if the 4.5 engine is certified for unleaded? And what type of injection it as?

Vasco:

All MB engines with aluminum heads (which is everthing since the 50s except the diesels) have hardened valve seats and are fine with unleaded gas. Only cheapo cars with the valve seat ground directly into the head casting had problems with unleaded fuel (read Ford and Chevy "old" six cylinders).

I believe a 76 will have hydraulic tappets and K-Jetronic (non-electronic version). Should be easy to tell, the D-Jet has a temp sensor in the air horn right up front and a ring main going around the engine on top of the injectors, the K-Jet has small pipes to each injector.
