What causes a problem with the timing chain?
Timing chain problems can appear as noise or engine performance issue, or both. Whether the symptom is noise or engine performance the root cause is always caused by the timing chain tensioner, guides or a worn and elongate chain.
Where is the timing chain located on a car?
A timing chain is a metal chain, as opposed to the timing belt which is made of rubber. The chain is located inside of the engine and needs to be lubricated by the oil in the engine so everything runs together.
Do you need to replace the timing chain tensioner?
If you need the timing chain tensioner replaced on your car, it requires replacing the chains, tensioner and possibly the guides and sprockets depending on age and visible wear. Timing chain tensioner replacement is an expensive and time-consuming repair.
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.
What causes the timing chain on a car to go out?
Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crankshaft. This causes the engine’s timing to fall out of calibration and often results in a misfire. The engine may also run poorly and lack accelerating power.
How does improper oil viscosity affect timing chain?
Improper oil viscosity can also have a serious impact on timing chain tensioner operation, variable valve timing solenoids and actuators, and direct injection fuel pump wear. In fact, using a motor oil viscosity other than the factory recommended oil can result in a check engine light, sludge buildup and catastrophic engine damage.
Can a bad oil filter cause timing chain wear?
In addition to oil change neglect and improper oil usage, using the wrong or low-quality oil filter can also cause accelerated timing chain wear. Should I also replace sprockets? Yes, Cloyes recommends that all components of the timing system be replaced at the same time.
What are the symptoms of a stretched timing chain?
Stretched timing chain symptoms 1 Noise. Timing chain noise is most noticeable on cold startup when oil pressure and flow is at its lowest. 2 Rough idle. 3 Check engine light. 4 Metallic debris in the oil. 5 Cold starts and short trips. 6 Stop and go driving. 7 Heavy loads.
