Clean upper face of cylinder block and measure the distortion. Standard: Less than 0.05 mm (0.0020 in) Limit: 0.2 mm (0.008 in) 2. If out of specification, resurface it. CYLINDER WEAR 1. Measure cylinder bore for out-of-round and taper with a bore gauge. If beyond the limit, rebore all 4 cylinders. Replace cyl- Standard inside diameter: 96.000 - 96.030 mm (3.7795 - 3.7807 in) Wear limit: Less than 0.20 mm (0.0079 in) Out-of-round (X − Y) limit: Less than 0.020 mm (0.0008 in) Taper (A − B) limit: 0.20 mm (0.0079 in) 2. Check for scratches or abrasions. If abrasions are found, hone cylinder bore. PISTON AND PISTON PIN CLEARANCE Check clearance between pistons and piston pins.
