There are four general motor oil types:
④ Dimensional numbers Shaft number 45: The seal suits the shaft diameter of ϕ45 mm. Housing bore number 70: The seal suits the housing bore diameter of ϕ70 mm. Width number 8: The seal width is 8 mm. ⑤ Special shape code
Over time, the rear valve cover gasket can degrade due to heat, pressure, and exposure to engine fluids, causing leaks. These leaks can lead to oil loss, engine damage, reduced efficiency, and even complete engine failure if left unchecked These leaks can lead to oil loss, engine damage, reduced efficiency, and even complete engine failure if left uncheckedIn addition to their performance benefits, LS1 spark plugs also contribute to improved fuel economy. By ensuring a more complete combustion process, these spark plugs help reduce the amount of fuel needed to achieve the desired level of power, resulting in lower fuel consumption and reduced emissions.
