How long does the timing chain last on a 2005 nissan sentra

Should last a very very long time, as in I wouldn't really worry about it. I noticed that the timing sprocket was all steel also. I mention the sprocket because 30 years ago we bought a new Buick Regal and within a couple of months the car crapped out. GM actually put plastic teeth on the timing sprocket and they broke off. Stupid idea I hope no other manufacturer tried. We replaced it with a steel sprocket and never had another problem in the 9 years we owned it.

I had a Sentra 1995, also with timing chain and steel parts, with more than 250 000 miles on it and never changed timing parts. Nissan engines are not the most powerful, nor economic but they last and require minimal maintenance. The exception is the 2.5 engine with head gasket that blows sooner than expected.

I'm always seeing cars that died long before their time because the timing belt or timing chain broke and the engine went out of time trashing an otherwise good engine. For those that didn't spend over 40 yrs in the shop fixing the cars other ruined I offer you this sound advice. I often hear it said that you don't need to replace a timing chain unless it is making noise. Not really true! When the noise begins the problem is you may need a new engine very soon kind of critical. Most people know to replace the timing belt even if they wait too long they knew. I spent my time fixing high end and expensive European luxury and sports cars. Most manufacturers recommend replacing the timing chain every 100,000. The chain stretches over time and this stretching retards the valve timing making the engine run with less power and more pollution. Replacing a timing chain is costly but far less than replacing your engine. Replacing the chain puts the engine back to brand new factory valve timing so the engine runs better and cleaner. No jumped time and no burnt valves. Burnt valves are most often the var ran too long with a stretched timing chain and the partially burnt gas collected on the hot valves building up over time until the valve can't close. Now you need a valve job and a timing chain that is "if" the rest of your engine isn't mostly dead from running in that filthy state. How many miles does a timing chain last? The metal links in the chain move on the tooth sprockets on the end of the crankshaft and camshaft so that they rotate together "in time". The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem.Jan 18, 2016 How Long Does a Timing Chain Last? | YourMechanic Advice www.yourmechanic.com › article › how-long-does-a-timing-chain-last Search for: How many miles does timing chain last?

Timing Chain System Frequently Asked Questions | What does a timing chain do? A timing chain synchronizes the rotation of the crankshaft and camshaft(s) ensuring proper value timing. When does a timing chain need to be replaced? The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles. If driving an older vehicle, or one with close to 100,000 miles, it is recommended to look for symptoms of the timing chain going bad or failing. As for me I replace timing chains in all my cars every 100,000 miles like clock work and my cars never jump time. When I buy a car with over 100,000 miles it gets a timing chain! I have had engines and trans run over 700,000 miles and I sold the car running and driving. I also service the transmission, change the brake fluid, power steering fluid, rear axle oil, and flush and refill with new coolant every 30,000. I hope this saves someone the engine, transmission, and the rest of their car from certain ruin.
