Sons 300m and I need help please!

When the water pump went south on mine and threw metal into the bottom end I put a crank kit in from oreileys. It was crank and all bearings. It ran about $250 Total with oem water pump and tensioner along with guides and gaskets and new motor mounts hoses and plugs and oil
Pump came to $900. So far about 500 miles on it without trouble.
