Cam eccentric on 340

TOTAL BS !! It should probably be replaced. It can be replaced on the car. If the key way on the eccentric is a loose fit on the Woodruff key it needs to be replaced. Also the woodruff key should be replaced. The factory torque spec for eccentric bolt is 35 ft. lbs. I would also use Blue Lock-Tite. Had one come loose many, many years ago. It left me in the middle of no where. Was inexpensive to fix but very inconvenient and a big tow bill.
