- Another method is the compression test, which checks if the spark plug is firing correctly. This test measures the engine's compression, indicating issues like worn pistons or valves. Low compression combined with a weak spark suggests a problem with the spark plug.
Friction modifiers: Friction modifiers help reduce friction when your engine is operating under high temperatures and with heavy loads. This additive can also help you maximize your fuel efficiency.
- 3. **Shaft Seal Dimensions** Shaft seals are used to seal the connection between a shaft and its bearing. They are typically characterized by their outer diameter, inner diameter, and length. Shaft seal dimensions must match the shaft and bearing dimensions to ensure a tight seal Shaft seal dimensions must match the shaft and bearing dimensions to ensure a tight seal

oil seal dimension.
- In the automotive industry, PU oil seals are commonly used in engine compartments, transmission systems, and hydraulic components. Their robustness and ability to function under high-temperature and high-pressure conditions make them ideal for these applications. Similarly, in the manufacturing sector, they are vital in pumps, compressors, and other machinery where oil leakage can lead to downtime and costly maintenance.
To do this, turn the engine with a socket on the crankshaft pulley bolt until the rotor arm is pointing to the plug contact of the timing cylinder (usually No. 1, check in the car service manual), and the timing marks on or behind the pulley show exactly top dead centre ( TDC ).

e3 20 spark plug. This not only benefits the air quality but also ensures that the vehicle meets emissions standards set by regulatory agencies.
Remove the cylinder head (See How to remove a cylinder head ), carefully peeling off the old gasket from the head or block. Make sure no dirt or carbon falls into the engine.
An overview of the different standard types of oil seals and their main characteristics is shown below.
