Engine looks beautiful btw, proper job!

I'd park the alternator issue for now, run it in then at oil change time replace and retorque it to the latest spec/parts and not lose any more sleep.

The main problem with these engines is they are so goddamn noisy normally you can't tell. I initially thought the squealing noise was the clutch on my 748 but when it stalled and wouldn't restart l realised and managed to catch it before it wrecked the engine. It still did a fair bit of damage but thankfully the crank was salvageable.
