I was driving to work the other day and my coolant belt snapped I didn’t catch it as quickly as I would liked I ended up grabbing a belt from work and installing it and drove home, but I drove a couple more days felt severe lack of power now it has this sound and dies when I rev it high it’s odd only the knock like sound happens when it’s throttled hard I replaced the crank bearings when I built the engine like five years ago I’m really hoping I don’t have to pull the whole engine. I have a spare head. Do you guys think it would be worth it just to replace the head gasket and see or pull whole engine to check rod bearings
