I recently pulled the engine from my 81 westfalia in hopes of repairing the severe oil leakage that it suffered from. The engine had been rebuilt one before for the previous owner. The van had been sitting idle for a few months when I went to start it to maneuver it into a suitable location for engine removal. When cranked the engine wouldn't turn over even with a jump. I could hear the starter functioning and was immediately suspicious of seizure. After removing the engine I tried rotating the crankshaft with a wrench. The engine will rotate through about 300 degrees but there is a point that the shaft will not rotate past from either a clockwise or counterclockwise direction. This is the case even with one side's head and push rods removed. I haven't removed the other side yet. Is this an "engine seizure" and if so do these symptoms indicate a specific condition? What should I do to assess the "rebuildability" of the engine? What are my replacement options for a portion or entirety of the engine? I prefer to attempt any work do be on it myself and of course at a minimum expense. Thanks,
