Assembly problems with the oil seal?
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.

The car head gasket, also known as the cylinder head gasket, is a critical sealing component in the engine that plays a pivotal role in maintaining the integrity of the combustion chamber. This gasket is designed to seal the cylinder head to the engine block, preventing the leakage of coolant, oil, and combustion gases. A properly functioning car head gasket is essential for ensuring optimal engine performance, preventing overheating, and maintaining the overall efficiency of the engine.
The sealing process involves the interaction between the rotating shaft and the elastomeric material, resulting in a dynamic barrier that prevents fluid leakage and maintains system integrity.
Purpose of oil seal
Place the ruler or straight-edge on edge diagonally across the head and block and look for gaps showing light anywhere between the ruler and block.
Proper preparation is crucial for successful oil seal installation. Ensuring that the seal, shaft, and bore are correctly prepared and aligned prevents seal failure, leakage, and premature wear of the components.
We just discovered that one of the seals on our pumping system is leaking. Do you have any ideas as to what could have caused this, and can you offer some advice for selecting a good seal?
