hydraulic tappets

The hydraulic tappets in your vehicle help maintain zero valve clearance and are also known as a hydraulic valve lifter. Here we will explain more.

Hydraulic tappets play an important role

The hydraulic tappets play an important role in maintaining a zero clearance between the valve and the rocker; they are also known as hydraulic valve lifters. The tappets help prevent the valves and rocker arm from binding together because they expand with the heat of the engine, but the tappets can also lead to noisy operation as they rattle against each other until reaching their operating temperature. Hydraulic tappets are also susceptible to wear and tear and were specially designed to compensate for the small tolerance required in the valves. Having a zero clearance prolongs engine life and leads to a quieter engine operation. Also, there's no need to adjust the valve clearance periodically since the lifters do this.

Hydraulic lifters

Situated between each engine valve and the camshaft, the hydraulic lifters consists of a hollow steel cylinder which contains an internal piston. The camshaft presses against the hydraulic lifter and will lift the valve in one of two ways, either via the rocker mechanism or with direct contact. The oil also needs to be under pressure when supplied to the lifters. The hydraulic tappets help make up what is known as the cam and valve train so consists of valves, push rods, rocker arms, the camshaft as well as the lifters. This train will regulate the fuel intake, ignition, compression and the waste gas expulsion simultaneously so the tappets play an important role within this.

They work as the crankshaft is synchronised by a belt or a chain and the timings can be quickened or slowed down to deliver the best level of efficiency and performance from the engine. However, components within the valve train can slip as these parts begin to wear down and the engine's performance will be affected by mis-timed valve openings which could, potentially, lead to serious engine damage.

Hydraulic lifters and the role they play

Most drivers will be unaware of hydraulic lifters and the role they play, but they will become aware of them when they fail ñ but how will drivers know this has happened? This will be an obvious symptom because a faulty hydraulic lifter will become much noisier and make a distinct sound. The noise will also have a quick rhythm and will be heard, regardless of whether the engine is hot or cold. Though the issue may not be a faulty lifter but maybe with dirt, wear and tear or a sticking valve. It also needs to be noted that should one of the hydraulic tappets need replacing that you may need to replace all of them to ensure they deliver years of trouble-free service. For this reason, it may be a good idea to take your vehicle to a professional should you suspect there may be a problem with the hydraulic tappets for a correct diagnosis and for them to carry out repair with quality replacements.
