3. Oil Leaks Oil leaks from the front of the engine can indicate that the timing belt cover seals have worn out. If oil seeps into the belt, it can lead to premature failure.
- In addition to their durability and reliability, metal cased oil seals are relatively easy to install and maintain. They are designed to fit securely into the housing or assembly of the equipment, ensuring a hassle-free installation process. Once in place, these seals require minimal maintenance and can be easily replaced when necessary, reducing downtime and maintenance costs.
- Over time, spark plug wires can deteriorate due to heat, moisture, and wear and tear. This can lead to misfires, rough idling, and decreased fuel efficiency. It is important to regularly inspect and replace spark plug wires as needed to maintain the overall health and performance of the engine

However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.

After the oil seal is positioned in the groove, apply even pressure to the oil seal using a seal driver or a similar tool. This will help to seat the oil seal firmly in the groove and prevent it from moving during use. Make sure to apply the pressure evenly and gently, as applying too much force can damage the oil seal or cause it to deform.
The cover is fixed by nuts or bolts on top, or by screws round the edge. Loosen them all and remove them with their washers. If there are several oil-sealing washers under each fixing, note their order.
