Removal, inspection and installation of valves (Opel Corsa B)

Removal

1. Remove the timing case

2. Prepare 8 clean plastic bags or plastic cups, labeling them in the order of the valve numbers (you can also use a large box divided into eight separate sections). Remove the valve drive levers, oil seals and hydraulic compensators one by one and place them in appropriately marked containers.

Installing the valve drive levers in an arbitrary order will result in a violation of the correspondence between the shape and degree of their wear and the wear of the working surfaces of the camshaft cams!

Examination

1. Check the surfaces of the valve drive levers that contact the cams for signs of wear and mechanical damage - replace defective levers. If defects are found in the levers, also check the condition of the working surfaces of the corresponding camshaft cams - they will most likely also be damaged or worn out.

2. Check the condition of the oil deflector caps and make any 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 compensators and the walls of their mounting seats with clean engine oil. Install the compensators in their original places.

2. Install the oil deflector caps on the valves.

3. Lubricate the valve drive levers with clean engine oil and install them in their original places, checking the correct fit on the compensators and valve stems.

4. Finally, install the timing case with the camshaft inserted into it (see section Removal and installation the cylinder head).
