The damper is located inside the front of the block head on the left and attached to it from the outside with two bolts

If the damper is worn or damaged, under certain engine operating conditions, resonant vibrations of the leading branch of the chain can occur, which can lead to chain jumping on the teeth of the camshaft sprocket and serious engine damage.

You will need: a screwdriver, a wrench (preferably a socket) "10".

Remove the cylinder head cover (see "Replacing the cylinder head cover gasket").

Remove the camshaft drive chain tensioner (see Replacing the camshaft drive chain tensioner).

Inspect the removed dampener.

If its working surface has a deep wear from the chain and chips, or there are cracks and breaks on the damper body, replace the damper.
