Rocker arms for cylinder heads – a key component of your engine
Rocker arms are crucial elements located within the cylinder head of internal combustion engines. Their main task is to transfer movement from the camshaft to the valves, ensuring proper opening and closing of intake and exhaust valves. In this category you’ll find a wide range of original and used rocker arms for cylinder heads suitable for various car makes and models.
How does a rocker arm work and where is it located?
This component is mounted directly in the cylinder head, acting as an intermediary between the camshaft and the valves. Movement or pressure from the camshaft is transferred by the rocker arm to open the valves, allowing for correct flow of the air-fuel mixture or exhaust gases. In modern engines, rocker arms often work together with hydraulic lifters, further improving valve operation.
Most common rocker arm faults – how to recognize them?
Although made from durable materials, rocker arms may wear out or get damaged. The most typical signs of failure include:
- ticking or knocking noises from the cylinder head area, especially during startup,
- decreased engine power or rough running,
- improper valve operation (premature or delayed opening/closing),
- increased fuel consumption,
- irregular valve clearance or its rapid changes.
Rocker arms are particularly prone to wear due to insufficient lubrication and operating under overheated conditions.
When to replace a rocker arm?
Replacement is recommended at the first signs of excessive wear or during cylinder head overhaul. Ignoring these issues can lead to serious engine damage and costly repairs.
Frequently asked questions about rocker arms
1. Can I replace a single rocker arm, or do I need a full set?
It is advised to replace all rocker arms on a cylinder head during repair, as wear often affects multiple parts at once.
2. Can rocker arms be interchanged between models?
No, rocker arms vary in length, profile and material – always select according to your specific engine model.
3. What are the effects of driving with a damaged rocker arm?
You risk damaging the camshaft, valves, or even the entire cylinder head.
