Timing Chain: Inspection

Remove front cover. Rotate crankshaft in counterclockwise direction to take up slack on left side of chain. Establish reference point on block (left side of chain) and measure distance to chain. Rotate crankshaft clockwise to take up slack on right side of chain. Force left side of chain out with fingers and measure distance between reference point and chain. Deflection is difference between two measurements. If deflection exceeds 0.500", replace timing chain and sprockets.
