Hydraulic lifters, checking
WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 2009 Volkswagen Golf, 2008 Volkswagen Golf, 2007 Volkswagen Golf, 2006 Volkswagen Golf, and 2005 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
Special tools and equipment
- Feeler gauge
- Wood or plastic wedge
NOTE:
- Replace each faulty hydraulic lifter complete only (cannot be adjusted or serviced).
- Irregular valve noises when starting engine are normal.
Work sequence
- Start engine and run until coolant fan has switched on once.
- Increase engine speed to about 2500 rpm and hold for approx. 2 minutes.
If the hydraulic lifters are still noisy, locate faulty lifters as follows:
- Remove intake manifold upper part. Refer to Intake manifold upper part, removing and installing .
NOTE:
Seal the intake ports in the intake manifold lower section with clean cloths.
- Remove cylinder head cover.
- Rotate crankshaft clockwise, until cam of lifter to be checked is pointing up.
- Determine clearance between cam lobe and hydraulic lifter.
If the clearance is greater than 0.2 mm:
- Replace hydraulic lifter.
If clearance is less than 0.1 mm or no clearance exists, proceed with check as follows:
- Push hydraulic lifter down lightly with a wooden or plastic wedge. If when lifter is pushed down a 0.2 mm thick feeler gauge can be pushed between camshaft and lifter, lifter must be replaced.
NOTE:
When new lifters have been installed the engine must not be started for about 30 minutes. The hydraulic compensation elements must settle or the valves will strike the pistons.
