Oil Pump : This is the heart of the automotive engine. The oil pump delivers the vital oil pressure to the various bearings, rings, lifters, camshaft(s), crankshafts, pistons, pins, seals and valves inside of the engine. Oil pressure is required to lubricate these various engine parts. Oil pumps vary in designs. A drive gear is needed to rotate the oil pump off of the crankshaft or camshaft. Pistons, vanes, and or gears are used to create the pressure. Most oil pumps regulate the oil pressure up to 50 or 60 lbs. Besides pressure, oil volume is also needed to sustain the engine’s needs. Oil volume is the amount of oil distributed through the engine and any given time.
When Do You Replace the Oil Pump?
Oil pump failures do occur. An engine can not run more than 2 minutes without oil pressure. If you loose oil pressure, you may notice: an oil gauge warning, oil light, tapping sounds from the engine or straight up engine failure. Low oil pressure may require an oil pump replacement or the oil sump may just be clogged up with sludge. Oil sludge can reduce the oil volume causing all of the same warning signs of a failing pump.
What are the Costs of Replacing the Oil Pump?
Most labor costs are high on oil pumps. Often, the oil pan must be removed. If the vehicle has a timing chain or timing belt, they also are usually required to be removed to access the pump. Oil pump labor can range from 2 to 10 or more hours to replace.
Is Replacing the Oil Pump a Good Idea?
In many cases of an oil pump failure, the engine may already be damaged due to lack of oil pressure. If bearings are already failing, changing the oil pump will not help. Metal shavings inside the engine are the best indicators that the damage is already done and the engine rebuild or replacement is the better option.
If you suspect oil pump failure, it is often best to tow the vehicle to the mechanic shop. Guy’s Automotive offers all types of engine repairs and more. Visit us for all of your engine problems and more.
