Are timing chains more reliable?
While timing chains are far more reliable, timing belts are far cheaper. This allows the manufacturer to save some money during production. Furthermore, timing belts used to be far quieter than timing chains, but this isn’t the case anymore in newer vehicles.
Do timing chains last longer than belts?
Most automakers recommend replacing the timing belt every 60,000 to 105,000 miles. Timing chains are heavier and more complex than timing belts, but they also last much longer. Really, unless there’s a problem, timing chains don’t have a replacement interval.
What does a timing chain do in an engine?
What does a timing chain do? A timing chain synchronizes the rotation of the crankshaft and camshaft (s) ensuring proper timing and allows the engine’s valves to open and close during each cylinder’s firing. The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.
When do you know to change the timing chain?
A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.
What happens if you skip a timing chain?
The timing chain can stretch, and that affects performance. Also, some vehicles have plastic camshaft sprockets, and if they overheat they can melt. Then the chain skips, and the engine stops. If the piston comes up at the same time as a valve fully opens, the valve could bend, and the engine could even be ruined.
Why do I have to use synthetic oil on my timing chain?
Most of the time, modern vehicles will only be able to use synthetic oil because they have to meet certain specifications to ensure the oil flows quickly, and with the proper pressure. The wrong oil can cause extra load on the chain and the engine will not be properly lubricated.
