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?
