We replace the camshaft seals when repairing the cylinder head and when oil leaks from under the seal

If we change the oil seals on the engine, then it is necessary to perform work to remove the drive and timing belts, as well as remove the phase regulator and the exhaust valve pulley

For clarity, we will show all the work on the dismantled cylinder head.

The polymer seal of 1.6L engines has a flat working edge (1) and a protective sleeve (2), which serves to install the seal on the engine (see Fig. 1).

Installing the exhaust camshaft seal

Be sure to use a protective sleeve, since this type of oil seal is very easy to damage. It is strictly forbidden to touch the polymer seal itself in order to prevent oil leakage after installing the seal on the engine.

- Screw the pin (1) of tool Mot.1632 into the camshaft (see fig. 2).

- Install the protective sleeve with the oil seal on it on the camshaft. While doing this, do not touch the stuffing box (see Fig. 3).

- Fit the pressure cap (2) and collar nut (1) of tool Mot.1632 (see fig. 4).

- Tighten the collar nut until the cap touches the cylinder head.

- Remove the nut, cap, protective sleeve and stud.

Installing the intake camshaft seal

- Install a protective sleeve with an oil seal on the camshaft, being careful not to touch the

oil seal with your hands (see arrow, Fig. 5).

- Press down on the protective sleeve in the center so that the oil seal is fixed in the seat.

- Pull out the protective sleeve so that the oil seal does not fall out of the seat (see Fig. 6).

- Screw the pin of tool Mot.1632 into the camshaft (see fig. 7).

- Fit the pressure cap (2) and collar nut (1) of tool Mot.1632 (see fig. 8).

Tighten the collar nut until the cap contacts the cylinder head.

Remove the nut, pressure cap and stud.
