im gonna take off the head to check for damage i dont think its a rodnock, bc it was the main bearings that were worn out not the rod bearings they were brand new and didnt see any damage on the rod bearings, mostly seen them on the main bearings but it wasnt that bad, but i did go under the car and the noise was coming from the top of the motor dont think its a rodnock, its gonna be something in the valve train
