- Proper installation of LS1 spark plug wires is also crucial for ensuring optimal engine performance. Wires should be routed away from hot surfaces and moving parts to prevent them from melting or becoming damaged. Additionally, each wire should be securely connected to both the ignition coil and the spark plug to ensure a reliable electrical connection.
3. Dust and debris are common reasons for oil seal failure.
• Machining of lip surface (stable oil drip under pressure)


Figure 4 shows the features of a JTEKT oil seal.
Oil seals have a flexible lip that actually rubs against the rotating shaft or housing to prevent leakage. The spring keeps the lip in contact with the shaft. Bearing isolator oil seals are dynamic seals that incorporate a rotor or rotating member and a stator or stationary member. The rotor actually turns with the shaft. Some oil shafts are bearing isolators with a labyrinth construction. Others incorporate simpler O-rings.

Oil seals operate by creating a tight barrier between two moving or stationary parts, such as a shaft and housing, to prevent oil from escaping and contaminants from entering the system. This is essential for maintaining the efficiency and performance of the machinery, as well as preventing potential safety hazards.
