Why does the engine make abnormal noise when the clutch is pressed?

The reasons why the engine makes abnormal noise when the clutch is pressed are: 1. Worn clutch disc; 2. Broken clutch pressure plate spring; 3. Loose release bearing; 4. Lack of lubricant. The solutions for abnormal engine noise when pressing the clutch are: 1. Replace the clutch disc; 2. Replace the clutch pressure plate spring; 3. Adjust the release bearing; 4. Replenish lubricant. The working principle of the clutch is: 1. When the vehicle starts, the driver presses the clutch, and the pressure plate separates from the friction disc. At this time, the pressure plate and the flywheel are completely out of contact; 2. When the vehicle is driving normally, the pressure plate is tightly pressed against the friction disc of the flywheel. At this time, the friction between the pressure plate and the friction disc is large, and relative static friction is maintained between the input shaft and the output shaft, with both rotating at the same speed.

The other day when I pressed the clutch while driving, I heard a strange 'squeaking' noise coming from the engine area, which scared me into thinking the car was falling apart. Later, I asked a friend to help check it out and found that the clutch release bearing was broken. This part is located near the flywheel, and if it's not lubricated enough or worn out, pressing the clutch will cause friction and strange noises. If you delay fixing it, it might even damage the pressure plate, requiring the entire clutch system to be replaced, which is both costly and troublesome. Last time, I spent over 800 yuan to replace it, and now I feel lucky that I fixed it early. I recommend everyone to pay attention to any changes in sound while driving and get the car checked at a workshop promptly—safety first. By the way, try not to keep the clutch in a semi-engaged state too often, as it accelerates bearing wear.

I just got my driver's license not long ago and bought a used manual transmission car to practice. The first time I pressed the clutch, I heard a 'clunk' sound. An experienced driver told me that this noise is most likely caused by clutch components, such as a worn release bearing or a warped pressure plate. These parts are responsible for disengaging the power, and once they start grinding or become loose, the engine will produce abnormal sounds. Later, I learned a simple self-check method: turn off the engine and slowly press the clutch to listen for the source of the noise; if the sound comes from the bottom, that's where the problem lies. Don't ignore it, as small issues can easily turn into big ones, and repairs could cost you at least a thousand. Sharing this with fellow beginners—when you encounter car problems, always ask the more experienced drivers. It saves money and peace of mind.

Engine noise when pressing the clutch? First suspect the release bearing - that small ring on the flywheel. When it fails, it squeaks when pressed, either due to dried lubrication or wear. If left unchecked, the clutch will suffer too. Get it checked ASAP - repairs are cheaper now.

Driving the old family car to pick up the kids, there's an annoying 'clunking' noise every time I press the clutch. I asked a mechanic, and he said the issue lies in the clutch release system—faulty bearings or pressure plates could cause abnormal engine sounds. Over time, it could even affect gear shifting safety, and breaking down on the road would be a nightmare. I replaced it preemptively, and now I make sure to check the clutch fluid and components during regular maintenance. Don’t put off small issues—safety comes first, and peace of mind for the whole family is what matters most.

When I was on a tight budget, I encountered a strange noise when stepping on the clutch. Upon careful inspection, it turned out the release bearing was dry. The reason is simple: friction between components increases during disengagement, and aging parts start making noise. If left unrepaired, it could damage the flywheel, and replacing the entire set could cost thousands. I recommend addressing it early—adding a bit of lubrication during maintenance can extend its lifespan. Money-saving tip: Avoid slamming the clutch, and regular maintenance can save you big bucks.
