Valve Seals: Removal

WARNING: This page is about a different car, the 2003 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore the engine must be retimed each time the damper is removed. Otherwise severe damage can occur.

Remove the camshafts. For additional information, refer to CAMSHAFTS .
- Remove the valve tappets and place them in order to one side.

WARNING: Always wear protective goggles when working with compressed air. This can prevent injury. Failure to follow these instructions can result in personal injury.

Unscrew the spark plug on cylinder No. 1 and connect the compressed air supply.

CAUTION: Use compressed air at 7 to 10 bars (100-150 psi).

NOTE: Place all parts in order to one side.

Using the special tools, apply compressed air to the cylinder.
- Using the special tools, compress the valve springs and remove the valve collects using some grease and a small screwdriver.
- Remove the valve spring retainers and the valve springs.
