What does a rattling timing chain sound like?
Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. Such a noise will reveal a loose timing chain hitting the inside of the timing chain cover every time it rotates. You might also hear a metallic slapping noise.
Why is my timing chain rattling?
Timing chain noise is commonly most noticeable during cold startup of the vehicle when oil pressure and oil flow is at its lowest. Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover.
Is Vectra C reliable?
The Vectras has earned a reasonable reputation for reliability, although according to the What Car? Reliability index, they have slipped in recent years and, overall, Vauxhall rates below average. The 2.2 diesel needs regular oil checks/top-ups, otherwise it could run dry and seize.
What are the signs of a faulty timing chain?
Signs of a Faulty Timing Chain
- Rattling Sound on Starting the Engine or Idling. A common finding in a vehicle with a bad timing chain is unusual rattling noise when the engine is started or when brakes are engaged.
- Misfiring Engine.
- Contaminated Engine Oil.
- Check Engine Light.
- Inability to Start the Engine.
Will thicker oil stop timing chain noise?
You can’t fix a timing chain issue (whatever it may be) with an additive. Usually, using a heavier oil can quiet down things like lifters, but I don’t think that would do much, if anything at all, with your timing chain noise. And a heavier oil may have some undesirable side effects.
What does a failing timing chain sound like?
A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.
How do you know if your timing chain is stretched?
Read the amount of stretch on the timing tab. For example, if the rotor tip began to move at 10° after TDC as measured at the timing mark, the chain has 10° of stretch. Any reading more than 4° to 5° is considered excessive and you need to schedule time to install a new timing chain and gear set.
Can too much oil affect timing chain?
Can Oil Affect Timing Chain? In most cases, timing chain stretch is caused by a lack of maintenance and regular oil changes. Oil that has worn out can no longer lubricate the chain, and the rollers and links will become worn out. The timing chain wears over time, which can affect the camshaft and crankshaft’s timing.
Is Vauxhall Vectra a good car?
