Water pump Impeller, Elbows if they are over 5 years old, Heat Exchanger if it has never been cleaned.
Start with the easiest things, the water pump and the thermostat. Install a new impeller and replace the thermostat.
Also check the oil heat exchanger. Pieces of the water pump blades break off and block the flow here. Pull off the hoses and back flush it.
Put a heat gun on the elbows and check against the good engine.
That should keep you busy for next weekend.
