Siezed engine, need options!
As the title states I bought an f02 750li that wouldnt start as a project car, today I learned that the engine is siezed and the crank pulley will only rotate partially when spun manually. I took the park plugs out and found that there was a bit of water on the plugs and they had rusted at the ends. Is this engine possibly fixable? Would an n62 fit as it is way cheaper? Could I swap in the engine and trans from an n54 and convert the car to a 740li without having to rewire the entire car? Help please guys!
