How to Deal with Valve Noise?

The solutions for valve noise are as follows: 1. If the valve clearance is too large, simply adjust the valve clearance. If the camshaft or valve lifter is worn, replace the camshaft or valve lifter. 2. If neither of the above situations applies, then the issue may be with the engine oil. If the oil viscosity is too high, simply switch to a lower viscosity oil. If the oil level is insufficient, add more engine oil. 3. For valve noise, as long as the owner performs regular maintenance, such as changing the oil according to the maintenance manual and checking the oil level regularly, this problem rarely occurs.

I used to often help friends with car engine issues. Valve noise is mostly due to excessive valve clearance or poor lubrication, which causes knocking sounds during operation. First, check the oil level and condition. If it's too dirty or low, add new oil and see if the noise reduces. If it still persists, you'll need to adjust the valve clearance. This usually requires professional tools to measure the gap size, then tightening or loosening the adjustment screws. If not addressed promptly, the valves may wear severely, leading to engine failure and increased repair costs. It's best to find a reliable repair shop to have them remove the engine top cover for a proper fix. Also, develop the habit of regular oil changes to reduce wear and tear—driving safety is the top priority.

I once owned a used car, and right after purchasing it, I noticed a ticking sound coming from the engine. After searching online, I learned it was valve noise, which made me a bit nervous. I checked the engine oil myself and found it was a bit low, so I added some. However, the noise didn't completely go away. I then consulted an experienced driver friend, who took me to a repair shop. The technician said the valve clearance was too large and adjusted it, solving the problem. This saved me a lot of money and time. A reminder to everyone: if your engine makes noise, don't delay. Insufficient lubrication is common, but adjusting the clearance is key. Otherwise, it can accelerate engine aging and affect your driving experience, especially during long-distance high-speed driving—address it early.

A ticking sound during engine idle is often caused by valve issues. When I encounter this, I first check if the oil level is normal and try adding some to see if the noise disappears. If there's no change, it's best not to drive for too long to avoid further damage. In most cases, adjusting the valve clearance or replacing worn components will solve the problem, and the cost is not high. It's recommended to check the engine operation during each maintenance session, as prevention is key.
