I have a international 574 with a C200 engine. Engine makes a tick or clicking noise. Speeds up as you increase on the throttle. I had it at a repair shop They inspected the top of the engine and told me they thought it was a crank bearing. I have now brought it home pulled the motor, pulled the pan off and I don"t see anything. No dis coloring and everything seems tight. My plan next is to pull the head. Take the pistons out and see what is going on there. Has anyone ran across this one C200 engine? Is there somewhere else I should be looking. This engine has a balancer on it and all seems fine with that"s well.
