Re: Splitting cases
The halves are aligned by three pins. Perhaps things are sticking at one of them.
But I wonder if you know what you're doing. The halves are a matched set that splits along the crankshaft bearings, possibly the most critical alignment on the engine. That's why they're not sold separately. IMO, replacing one half sounds like you're playing with fire unless you're a hell of a machinist.
