I made a total rookie mistake and ran my motor dry for five minutes after putting it back together. Had a total scatter brain moment. After putting the right amount of oil in I'm now hearing a high pitch squeaky noise which I didn't hear before I took it apart. I had to lift it to change the oil sump gasket and I took the heads off to clean the valves. Is the squeaky noise from a damaged oil pump or is it something else? Not sure where to go from here tbh.
