Overview - VALVETRAIN: Notes
WARNING: This page is about a different car, the 2023 Volkswagen Atlas. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The cylinder head and the cylinder head cover must be replaced together.
Do not start the engine for approximately 30 minutes after installing the camshafts. The hydraulic lifters must seat themselves (otherwise the valves will crash into the pistons).
After working on the valvetrain and engine, carefully rotate by hand at least two full turns to be sure that valves do not strike pistons when starting.
Always replace the gaskets and seals.
After performing work on the chain drive the adaptation value in the engine control module must be adapted. To do so, turn on the ignition and select the following menu item on the Vehicle Diagnostic Tester:
