Removal
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.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the camshafts.
3. NOTE: 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.
Remove and inspect the valve tappets.
4. Remove the spark plugs.
5. CAUTION: Use compressed air at 7 to 10 bars (100-150 psi). Do not disconnect the compressed air from the cylinder until the valve
spring, valve spring retainer and valve collet is installed. Any loss of air pressure will allow the valve to fall into the cylinder.
Connect compressed air supply to the No. 1 cylinder.
6. NOTE: Place all parts in order to one side.
