2.0L engine
Caution! If the valve control parts are to be reused, they must be installed in their original locations. To avoid mixing up the parts, make a panel to store them.
Removal
1. Remove the cylinder head and place it on wooden planks so that the valves are supported underneath.
2. Remove the oil seals.
3. Tilt the cylinder head aside and remove the valves from the guides.
4. Clean the valves.
5. Valves with burnt-out valve heads, valve head height (h) that is too low, worn or scratched stems must be replaced. For limit value (h), see Valve Dimensions table.
6. The repair shop can check the valve stem for runout and make adjustments to the valve seat angle. The maximum runout of the valve stem and valve seat is 0.03 mm.
Attention! When performing any valve machining operations, keep in mind that the valve plate angle is a = 45° + 15°. Note: The valve stem and valve pin for 2.2/2.5 liter engines have 3 annular grooves.
Installation
1. Before installing the valve, check the valve guides and, if necessary, rework the valve seat.
2. Clean the valve stem where the stem parts meet.
3. Lightly lubricate the valve stem and valve guide with engine oil and install the valve.
4. Install new oil seals.
5. Install the valve spring.
6. Install all other valves, do not confuse the inlet and outlet valves.
7. Install the plate plunger.
8. Install the cylinder head.
