Removing
1. Remove the timing case
2. Prepare 8 clean plastic bags or plastic cups labeled in valve order (you can also use a large box divided into eight separate sections). Remove the valve actuation levers, oil seals and hydraulic compensators one by one and place them in appropriately marked containers.
Removal of levers of a drive of valves
Removing oil seals
Removing hydraulic valve clearance compensators
Installing the valve drive levers in an arbitrary order will lead to a violation of the conformity of the shape and degree of their wear to the wear of the working surfaces of the camshaft cams!
Examination
1. Check the surfaces of the valve drive levers in contact with the cams for signs of wear and mechanical damage - replace the defective levers. In case of defects in the levers, also check the condition of the working surfaces of the corresponding camshaft cams - most likely they will also be damaged or worn out.
2. Check the condition of the oil seals, make the necessary replacements.
3. If there is no certainty in determining the condition of the hydraulic compensators, they should also be replaced - checking the correct functioning of the compensators is not possible.
Installation
1. Lubricate the hydraulic lifters and the walls of their seats with clean engine oil. Install the compensators in their original places.
2. Install valve stem seals.
3. Lubricate the valve drive levers with clean engine oil and install them in their original places, controlling the correct fit on the compensators and valve stems.
4. Finally, reinstall the timing housing with the camshaft embedded in it (see Section Removal and installation of a head of cylinders).
