Check Valve Timing

This document provides instructions for checking the valve timing on a vehicle. It lists the special tools needed, which include a spark plug spanner, torque wrench, and dial gauge. The test procedure involves removing parts like the exhaust gas recirculation valve and coolant pipe. A dial gauge is used to check that the crankshaft is at top dead center on cylinder 1. The camshaft holes must be correctly aligned and a camshaft clamp must fit fully in the openings to confirm proper timing.

Checking valve timing

Special tools and workshop equipment required


t  Spark plug spanner -3122 B-
t  Torque wrench -V.A.G 1331-
t  Dial gauge -VAS 6079-
t  Puller -T10094-
t  Dial gauge adapter -T10170-
t  Camshaft clamp -T10171-

   
Test procedure

–  Remove exhaust gas recirculation valve -N18- → Chapter.


 
–  Unhook wiring harness (not shown in the figure) on the coolant pipe -4-.

–  Remove bolts -5- from coolant pipe -4-.


–  Remove bolt -2- from cap -1-.

–  Take caps -1- and -3- off. Collect leaking engine oil with a cloth.

–  Remove spark plug from cylinder No. 1. To do this use puller -T10094- and the
spark plug spanner 3122 B → Chapter.

 
–  Turn the dial gauge adapter -T10170- to limit stop into the spark plug thread.

–  Set dial gauge -VAS 6079- with the extension -T10170/1- up to limit stop and clamp
with the clamping nut -arrow-.

–  Set crankshaft in engine D.O.R. to TDC cylinder No. 1. Note the position of the dial
gauge indicator.

 
The holes -arrows- in the camshafts must stand as shown. If necessary turn crankshaft
one turn further (360°).

  Note

t  If the crankshaft was turned more than 0.01 mm past the TDC, the crankshaft must
be turned again approx. 45° against engine direction of rotation. Then turn the
crankshaft in engine D.O.R. to TDC cylinder No. 1.
t  Max. permissible deviation of TDC cylinder No. 1: ±0.01 mm.

 
–  Fit camshaft clamp -T10171- to limit stop into the camshaft openings.

The retaining pins -arrows 1- must engage into the holes -arrows 2-. The inscription


“TOP”-arrow 3- must be legible from above.
If the camshaft clamp -T10171- can not be inserted up to limit stop into the camshaft
openings the timing is wrong and must be adapted again → Chapter.

The timing is OK when the camshaft clamp -T10171- can be inserted into the camshaft
openings up to limit stop.

Further assembly is basically the reverse of the dismantling procedure. During this
step, observe the following:
t  Renew seals for the camshaft sealing caps and lubricate before installing.
t  Installing exhaust gas recirculation valve -N18- → Chapter.
