Mr. Ba, a meticulous grocery store owner in Hanoi’s Old Quarter, cherishes his trusty truck, a loyal companion for over a decade. He meticulously maintains it with regular oil changes at Tuan Anh Garage on Nguyen Trai Street. Recently, however, a disconcerting noise began emanating from the vehicle whenever it traversed uneven roads.

Worried, Mr. Ba took his truck to the familiar Duc Minh Garage on Cau Giay Street. After a thorough inspection, the mechanic declared, “Your tappets are worn out! They need replacing immediately to prevent further damage.” Mr. Ba was surprised; such a small component held such significance.

Car Engine Tappets

What are Engine Tappets?

Engine tappets, also known as valve lifters or cam followers, are small components within the valve train of an internal combustion engine. Their crucial role is to transmit motion from the camshaft to the intake and exhaust valves, ensuring precise and synchronized air intake and exhaust processes.

The Small but Mighty Role of Tappets

Despite their diminutive size, engine tappets play a vital role, directly impacting engine performance and longevity:

Ensuring a Tight Seal: Tappets ensure a tight seal between the valves and their seats, preventing air leaks in the combustion chamber, maintaining pressure, and optimizing engine performance.
Noise Reduction: Tappets eliminate the gap between the camshaft and valves, minimizing noise and vibration during engine operation.
Extending Engine Lifespan: Quality tappets contribute to smoother engine operation, reducing friction and wear, thus prolonging the lifespan of the engine and related components.

Common Types of Engine Tappets

Currently, two primary types of engine tappets are prevalent:

Mechanical Tappets: These tappets have a simple design and are cost-effective but require periodic adjustment to maintain accurate valve clearance.
Hydraulic Tappets: These tappets automatically adjust valve clearance, eliminating the need for periodic adjustments and promoting smoother, more efficient engine operation. However, they are more expensive than mechanical tappets.

When Should Engine Tappets be Replaced?

According to Mr. Nguyen Van An, a technician at Xuan Lan Garage in Ba Dinh District, engine tappets typically last for 80,000 – 100,000 km. However, replacement should be considered sooner if the following signs are observed:

A clattering noise from the engine during operation, especially during a cold start.
Sluggish performance, reduced power, and poor acceleration.
Higher than normal fuel consumption.
