On the other hand, with the exception of freak accidents, if one part of the kit is worn and failing, it’s likely that the other parts aren’t far behind. The good news is that locating a singular part of the kit that is broken can save you some money, since replacing one part is cheaper than replacing everything. If you have the right know-how and tools, you can do all of that yourself, but most people are going to have to rely on a mechanic for this. Unfortunately, finding the defective part and replacing it is about all you can do to stop the rattling you may be hearing. Like the plastic shoes, the problem may not be the chain at all, but this part, which is much cheaper to replace if that’s what you have to do. If it’s defective, a loose shaft that is vibrating when the engine is running could be what is causing the rattling noise. Those are super cheap to replace if that is the case.Īnother possibility is the water pump. However, there are some parts of the setup that could be the cause of the rattling that may not be immediately obvious.įor instance, the plastic shoes that direct the chain can break down or loosen over time, and the rattling could be caused by them, not the chain. You should check the bearings and sprockets for the exact same reason, and of course, the chain itself. If the tensioner is defective, it’s much cheaper to replace that alone than it is to replace the entire kit. The tensioner should be checked first, as its inability to keep the chain tight is usually a source of the rattling. If not, it’s best to leave this part to a mechanic as well. Naturally, this is something you should only do if you actually know a thing or two about car engines. What you can do before taking the car to a mechanic is trying to determine which part exactly is causing the rattling. In some cases, multiple parts, or even the entire system, may have to be replaced. That’s because the only real way to stop the timing chain rattling is to replace the part that is causing it to happen. The reality is, unless you yourself are very well-versed in car engines and fixing them, you will probably need a mechanic no matter what. OK, so here’s the bad news: this isn’t one of those problems that have a nifty DIY fix that will solve your problem.

(Symptoms + Costs) So, it’s best to fix a loose timing chain as soon as you notice it if you can. Needless to say, that is very bad and could wreck your engine big time. If the timing chain gets really loose, it could fly off of the sprockets during operation and get stuck elsewhere in the engine. The rattling isn’t the worst of your problems either. So, if a loose chain is bouncing all over the place and causing rattling noise, it’s probably the tensioner that is actually compromised. Normally, the tensioner would prevent a loose timing chain from being an issue. It can rattle due to being loose because it’s bumping against surrounding plastic or other parts of the engine. The biggest problem is that the timing chain will stretch over time, which loosens its fit and allows it to bump against multiple parts of the setup. That said, it’s usually the chain itself that is the root of the problem. The system usually includes the chain itself, some sprockets that hold the chain, a tensioner, a water pump, and some ball bearings to help the chain move in the right direction.Īs you can see, there are several components here, meaning there could be multiple reasons for that darn rattling. To start, we should establish what components most timing chains have.
