Replacing the camshaft seal (VW Golf 2)

The camshaft seal can be replaced without removing the engine from the vehicle.

The oil seal is located behind the toothed pulley of the camshaft. In order not to damage the surfaces of the cylinder head and camshaft, you need to use special device No.2085. A description of replacing the oil seal using this device is given below. If it is missing, you need to use a spatula with a curved end.

Loosen the generator mount, move it to the center and remove the V-belt.

Remove the timing belt cover secured with three bolts.

Turn the crankshaft and set the piston of the 1st cylinder to TDC. Use the V-belt pulley bolts to rotate.

Loosen the timing belt tensioner (see here) and remove it from the camshaft pulley. The belt should be secured properly so that it cannot move on the remaining toothed pulleys. At the same time, it should not be bent too much.

Lock the camshaft timing pulley (for example, using an old belt), loosen the pulley mounting bolts.

Remove the retaining ring from the shaft.

Screw a bolt with a washer into the shaft journal so that it protrudes by 15 mm.

Take special tool 2085 (see figure 62) and turn the inner part A two turns (about 3 mm). In this position, lock bolt B.

Lubricate the threaded head of the device and put it on the shaft until it stops in the seal. Carefully screw the device into the seal.

Loosen bolt B and screw in inner part A until the seal is removed.

Secure the fixture in a vice and remove the seal with pliers.
