How does a timing chain work? What are the signs of a bad timing chain? What is the purpose of a timing chain? When should I replace my timing chain?
A timing chain is lubricated by the engine oil.
Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster. A chain tensioner could be operated by a spring-loaded mechanism or oil pressure. The timing chain is a major component in your engine. If the timing chain is stretched badly, your vehicle can stall in traffic causing a hazard to you and the vehicles around you. The vehicle seems to be working harder than normal.
Your car will not start at all, indicated a complete timing chain failure. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crankshaft.
While a timing chain will usually last far longer than a timing belt, it will suffer from wear and tear and will need replaced at some point during the life cycle of the vehicle. If possible, it is best to get an estimate before approving any work.
