Use only a gasket scraper or razor blade on the cylinder head.

Caution! Be very careful around the oil channels for the variable valve timing solenoid. This applies to both the camshaft cover and the
cylinder head. The solenoid is extremely sensitive to impurities.

Dry and blow all surfaces clean.

Preparations

Carefully tap the end of the valve stem to ensure that the valve is correctly located in the seat.
Use a plastic, aluminum or brass drift to protect the valve and the surface of the tappet.
The sound made by tapping reveals if the valve is correctly seated.

Installing the camshaft and tappet

Install both the tappets for the inlet valves at cylinder 1.
Check the notes made earlier. Select new tappets if necessary.

Note! Only install two tappets. The tappets should be placed by the same cylinder!
