Valve Seals: Removal

WARNING: This page is about a different variant/trim than selected.
CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.
CAUTION: The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore, the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING .
  2. Remove the camshafts. For additional information, refer to VALVE TRAIN COMPONENTS - EXPLODED VIEW  and CAMSHAFTS .
    3. CAUTION: If the camshafts and valve tappets are to be reused, mark the location of the valve tappets to make sure they are assembled in their original positions.
    NOTE: The number on the valve tappets only reflects the digits that follow the decimal. For example, a tappet with the number 0.650 has the thickness of 3.650 mm.
  3. Remove and inspect the valve tappets. For additional information, refer to ENGINE SYSTEM-GENERAL INFORMATION .
    4. WARNING: Always wear protective goggles when working with compressed air. This can prevent injury. Failure to follow these instructions can result in personal injury.

  4. Unscrew the spark plug on cylinder No. 1 and connect the compressed air supply.
    5. NOTE: Place all parts in order to one side.
  5. Apply compressed air to the cylinder and remove the valve spring.
