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 we need 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.

Polymeric camshaft oil seal: 1 - oil seal lip, 2 - protective mounting sleeve

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 oil seal

Be sure to use a protective sleeve, as 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.

Replacing the camshaft seals of the K4M engine

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

Replacing the camshaft seals of the K4M engine

- Install a protective sleeve with an oil seal put on it on the camshaft. When doing this, do not touch the gland (see Fig. 3).

Camshaft oil seal installation: 1 - collar nut, 2 - pressure cap
  • - 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 oil seal

Replacing the camshaft seals of the K4M engine

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

gland by hand (see arrow, Fig. 5).

- Press the protective sleeve in the center so that the oil seal is fixed in the socket.

Replacing the camshaft seals of the K4M engine

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

Replacing the camshaft seals of the K4M engine

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

Installing the oil seal on the camshaft: 1 - collar nut, 2 - pressure cap
  • - Install the pressure cap (2) and collar nut (1) of tool Mot1632 (see fig. 8).

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

Remove the nut, pressure cap and stud.
