Frequently Asked Questions (FAQs)

1. Is engine valve adjustment necessary?

Yes, engine valve adjustment is necessary. Incorrect valve clearance can lead to poor performance, rough idle, and potential damage to the valves, camshaft lobes, or rocker arms. Proper valve adjustment ensures that the engine can operate at peak efficiency and breathe normally.

2. How much does it cost to get valves adjusted?

The cost of valve adjustment can vary depending on the make and model of your car. On average, auto shops or mechanics charge around $150-$300 for the adjustment. The process involves removing the valve cover and measuring the space between intake and exhaust valves and their lobes using feeler gauges.

3. Can engine valves be adjusted?

Yes, engine valves can be adjusted. Many modern engines are designed with shims atop buckets, allowing for adjustment. With the necessary shims and a special tool to depress the bucket, valves can be adjusted one cylinder at a time.

4. Is it difficult to adjust valves?

No, adjusting valve lash is a relatively simple task. Despite the intimidating appearance under the rocker arm cover, it is actually easier, cleaner, and less environmentally damaging than an oil change.

5. Can I drive my car if it needs a valve adjustment?

It is not recommended to drive a car that needs a valve adjustment. If the valvetrain is out of adjustment or the lifters are stuck, it can result in a tapping noise on the top of the engine and potential damage to the engine if driven.

6. What happens if you tighten valves too much?

Tightening valves too much can deform the tubing and connection, leading to cracks and gaps where fluid can leak out. It is important to adjust valves correctly to avoid damaging the engine.
