The camshaft seal may be replaced on an installed engine if leaks are found near this location.
The seal is located behind the camshaft drive gear. You will need tool 2085 or press the seal out with a bent lever. You will need to remove the front of the car.
Remove all drive belts of various units from the end of the engine.
Turn the engine until the first cylinder is at TDC. The vibration damper and drive gear must be aligned.
Engines with two valves per cylinder
Loosen the drive belt tensioner roller and remove the drive belt. The belt should be secured in a suitable manner so that it does not slip off the crankshaft gear. However, the belt should not be tied so that it does not break. The engine must not be turned over after this.
Holding the camshaft drive gear in a suitable manner (for example, put an old toothed belt on a gear), loosen the gear bolt. Remove the bolt and washer.
Use pliers to remove the woodruff key from the camshaft.
Screw the camshaft gear bolt with washer as deep as possible into the end of the camshaft.
Take the puller 2085 in your hands, unscrew the inner part (A) by two turns (approximately 3 mm) from the outer part and lock it in this position using the locking screw (B). The same puller can be used to remove the front crankshaft oil seal.
Lubricate the threaded head of the device, insert it into the camshaft seal and, while simultaneously pressing on the ratchet, screw the device into the seal.
Loosen the knurled screw (B) on the tool and screw the inner part (A) into the camshaft until the seal comes out.
Clamp the device in a vice and pull out the seal with pliers.
Engines with five or four valves per cylinder
Exhaust camshaft oil seal
Remove the timing belt.
While holding the drive shaft gear from turning with a suitable means, loosen the bolt in the center.
Mark the drive gear with a felt-tip pen on the outside so that it can be installed in its original position and then removed from the shaft. Using tool 2085, replace the camshaft seal in the same way as described for the 2-valve-per-cylinder engine.
When installing the gear, pay attention to the previously made mark. Hold the gear properly and tighten the bolt to a tightening torque of 85 Nm.
Intake camshaft oil seal
Disconnect the Hall sensor plug and unscrew the Hall sensor housing from the cylinder head.
Unscrew the shutter (blend) of the Hall sensor.
Take the puller 2085 in your hands, unscrew the inner part (A) by two turns (approximately 3 mm) from the outer part and lock in this position using the locking screw (B).
Lubricate the threaded head of the device, insert it into the camshaft seal and, while simultaneously pressing on the ratchet, screw the device into the seal.
Loosen the knurled screw (B) on the tool and screw the inner part (A) into the camshaft until the seal comes out.
Clamp the device in a vice and pull out the seal with pliers.
Lubricate the edge of the new seal and its outer surface with oil. To install the new seal, use a piece of pipe of a suitable diameter. The pipe must fit completely against the outer surface of the seal around the circumference.
Place the seal evenly and drive it flush with the cylinder head. Do not drive the seal completely, otherwise it will block the oil drain hole. You can replace the seal in the same way as described for replacing the front crankshaft seal.
When attaching the Hall sensor, pay attention to the correct installation of the shaped washer. The curtain must also be installed correctly. This is ensured by the presence of a recess in the camshaft.
