Valve Timing, Checking: Notes

WARNING: This page is about a different car, the 2009 Volkswagen GTI and 2008 Volkswagen GTI. However, it is still accessible from the selected car via links, so may be relevant.

-- Remove the upper timing chain cover. Refer to UPPER TIMING CHAIN COVER .

-- Remove the noise insulation. Refer to Description and Operation .

-- Disconnect the right charge air hose at the coupling.

-- Rotate the vibration damper, from underneath, in engine rotation direction to Top Dead Center (TDC) -arrow-.

NOTE:

Use a ratchet with a 24 mm socket to rotate the vibration damper. Rotate the crankshaft first to TDC and then again approximately 45° in the opposite direction of the engine rotation. Next, rotate the crankshaft in engine rotation direction to TDC.

If the arrow mark on the lower timing chain cover is no longer visible, set the engine to TDC using the dial gauge -VAS 6079-, refer to SETTING THE ENGINE TO TDC USING THE DIAL GAUGE -VAS 6079- .

The notch on the vibration damper must line up with the arrow mark on the lower timing chain cover (use a inspection mirror, if necessary).
The marks -1- on the camshafts must point upward.

-- Measure the distance from the outer edge -A- to the mark -B- on the intake camshaft.

Specified value: 61 to 64 mm.

-- Once the specified value is reached, measure the distance between the mark on the intake camshaft -B- and the mark on the exhaust camshaft -C-.

Specified value: 124 to 126 mm

NOTE:

If one tooth has an offset, there will be a deviation of approximately 6 mm from the specified value. Install the timing chain once again if there is an offset.
