If your car's engine is making an abnormal noise, it could be a sign that the lifters are going bad. The lifters are what help to push the valves open and closed as the engine runs. If they become damaged or worn down, they can start to make noise.
There are a few different ways that you can try to quiet noisy lifters. One is to add oil additives to your engine oil. These additives can help to lubricate the moving parts of the engine and quiet down any noises. Another option is to use a higher quality motor oil. This can also help to reduce friction andquiet noisy lifters. Finally, you may need to have your lifters replaced if they are severely damaged or worn out.
