Oil Pump

The

oil pump

pushes oil through the oil filter and then supplies oil to vital engine parts including the crank and camshaft, cylinder walls and piston rings, valve train, cam lifters and the timing gears or chain. Engines require lubricant in the form of motor oil, and this must be kept moving around the engine. Loss of oil supply to the car engine will usually result in catastrophic failure very quickly. The

oil pump

is the means by which the oil is circulated around the engine.
Faulty

oil pumps

can be difficult to diagnose, but should always be investigated when the oil low pressure light is flickering or engine components such as hydraulic followers are making louder than usual tapping noises.
Quality

oil pumps

 are made of solid metal and are generally pretty sturdy. Nonetheless their proximity to the engine and exposure to the environment can cause corrosion necessitating their eventual replacement. This must be done before the pump ceases to work to avoid engine damage.
 

Oil Pump Kit

The

oil pump

is essential to engine operation and keeps oil circulating continuously in order to lubricate the moving parts of the engine. An

oil pump

kit contains everything needed to replace the

oil pump

of a vehicle. This includes the gasket required to seal the

oil pump

and an oil filter to prevent harmful impurities in the oil from entering the engine.

Oil pump kits

 are needed, when the pump succumbs to corrosion and must be replaced to prevent the engine from becoming damaged by lack of lubrication.
