RL1048 O-RING, OIL PRESSURE REGULATOR – 1F ENGINE TOYOTA LAND CRUISER – Replacement for Toyota P/N: 90301-10042 (EN3-3)

We simply LOVE F/2F Toyota Engines and we will continue our pursuit of preservation and advancement of these engines! But, preservation of your Land Cruisers engine at the oil level is paramount as OIL IS LIFE! This little O-ring helps maintain the pressure of the oil pressure regulator of the F-Series engine. ALL IN EFFORT TO SAVE AN F!

The oil pressure regulator serves as safety valve preventing the high pressure oil discharged from the oil pump to rise above a specified value by means of the adjusting valve. The engine is equipped with an oil filter assembly incorporating a removable type element. The function of the oil cleaner is to filter the engine oil flowing thru the filter from the oil pressure regulator, and removing any foreign element contained in the oil.
