Rubber O.D. wall - The primary function of the main bearing oil seal is to create a barrier between the high-pressure oil compartment and the low-pressure environment outside the engine. This barrier is essential because oil under high pressure inside the engine can cause severe damage if it leaks out. The oil seal prevents this leakage by creating a tight seal around the crankshaft, which rotates at high speeds during engine operation.

Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.

Regular inspection and maintenance of auto parts oil seals, including the 99 Camry oil pump seal, are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the vehicle's systems.
The mating surfaces of the head or block must be perfectly clean, flat and smooth.
Even the slightest chip or dent can cause contaminants to infiltrate your oil seal. If there are any scratches on the shaft, a leak path may develop, allowing the lubricant to drip. To protect the shaft from damage, wrap it in a mesh rubber screen and store it vertically in its compartment. This way, it can be shielded from potential cracking.
Detergents: This additive isn’t like your laundry detergent! It focuses on preventing deposits, rust, and corrosion from forming on the piston ring area, piston under-crown, and other surfaces that tend to overheat.
