Removal And Installation: Camshafts: Removing

WARNING: This page is about a different car, the 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The sealing surfaces of the cylinder head cover and the cylinder head must not be reworked.

The camshaft bearings are integrated in the cylinder head and cylinder head cover. The tension must be released from the camshaft timing chain before removing the cylinder head cover.

If the cylinder head cover was removed, the sealing cap must be replaced.

All cable ties which are opened or cut off when removing, must be replaced in the same position when installing.

CAUTION:

When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.
To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.

-- Remove the vacuum pump. Refer to Removing .

-- Remove the noise insulation. Refer to NOISE INSULATION OVERVIEW .

-- Remove the camshaft timing chain guide rail -3- by unlocking the latch with a screwdriver and pushing the guide rail forward.

NOTE: When the lower timing chain cover is installed, the loose chain on the crankshaft cannot jump off.

-- Remove the camshaft timing chain from the chain sprockets.

CAUTION: Danger of damaging the valves, piston head and lower timing chain cover.

If the camshaft timing chain was removed from the cylinder head, then the crankshaft may not be rotated further.
Panels are installed on the lower timing chain cover to prevent the chain from falling down. The panels can bend if the crankshaft is rotated when the chain is loose.

-- Remove the ignition coils with output stages, refer to IGNITION COILS WITH POWER OUTPUT STAGES , and lay the wiring harness to the side.
