Here we go again. I rebuilt or replaced lifters. Replaced rocker shafts and push rods. I inspected piston tops and found them to look normal. She ran like a champ for 25 miles. Then, #4 intake rocker arm broke. Thats 5 intake arms now. Not a single exhaust rocker arm. This makes no sense. I guess the head is coming off now. If it were one or two of the same ones I'd say its a valve or guide. But,it's a different one each time. I'm stumped.
Glenn,
