oil valve cover gasket. It is important to ensure that the gasket is installed correctly and that the valve cover is tightened to the manufacturer's specifications to prevent leaks.
WHAT ARE THE TYPES OF OIL SEALS?
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:

Description
Heavy Duty Wheel Seals and Agricultural Equipment Seals can be divided into AP type, CRS type and ST type. Mainly be used in heavy pollution of agricultural machinery, construction machinery, mining equipment and trucks, buses and other environments. Compared to TC type, with special internal lubrication design, making it closed to the rotary shaft seal and bearing assembly which prevent external dirt effectively; a specially designed multi-lip inside the seal, makes it to achieve the function. Multiple external sealing lip design effectively prevents outside dirt and grease leakage immersion; the internal high-quality grease (butter) prevents muddy and water immersion.
