An oil seal is designed to perform three major functions: to prevent lubricants from leaking outside the seal even under high pressure, to act as a barrier to retain the lubricating oil, and to prevent dirt and other contaminants from entering the unit.

The 99 Camry oil pump seal is a critical component in the engine system of the Toyota Camry. This seal is responsible for preventing oil leaks and maintaining the proper lubrication of the engine's oil pump. The integrity of the oil pump seal is essential for sustaining the oil pressure and ensuring the efficient operation of the engine. Proper maintenance and replacement of the 99 Camry oil pump seal are crucial for the performance and longevity of the vehicle.

Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.

For the housing stop installation technique, set the seal depth flush with the bore’s interior shoulder. This technique ensures that the seal is perfectly aligned with internal housing components. A depth gauge can be crucial here to confirm that the seal is positioned correctly.

Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.

On some engines you have to remove the clutch-housing cover to reach the rear nuts.

Oil Gasket Seal:

Oil seals, also known as rotary shaft seals or lip seals, are a specific type of gasket designed to prevent the leakage of oil or other fluids in rotating shafts. 

This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.
