- Proper installation and maintenance of skeleton oil seals are crucial for their effectiveness. Any damage or wear to the seal can compromise its ability to prevent leakage and contamination, so regular inspections and replacements are necessary to ensure optimal performance.
- Next, remove the valve cover screws or bolts, taking care not to strip them in the process. Some recommend applying a bit of penetrating oil to these fasteners before removal to ease the process. With the screws removed, gently pry off the valve cover, being cautious not to damage the gasket residue on either the cover or the head.

Selecting Quality Gaskets and Spark Plugs
A spark plug ignition coil plays a crucial role in the functioning of an internal combustion engine. It is responsible for generating the high voltage needed to create a spark within the combustion chamber, igniting the air-fuel mixture and initiating the power stroke. Without a properly functioning ignition coil, the engine would not be able to start or run efficiently.

Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
