Signs Your Timing Chain Kit Is Failing (Before Catastrophic Engine Damage Occurs)

The timing chain of your car is the unacknowledged hero of your engine. It is unlike its rubber belt counterpart as it is expected to last to the engine lifetime. Designed to live- that doesn't mean impervious. Wear, bad service or the failure of tensioners may cause stretched or breaking timing chain kit. Taking no attention to the symptoms usually leads to the disastrous state of the engine- broken valves, crumpled pistons, and the cost of fixing, which exceeds the cost of the car. It is important to nip it in the bud. The following is what to look and hear:

Early Warning Signs: Don't Ignore These!

1. The Tell-Tale Rattling (Especially at Startup):This is the most common and serious symptom of initial part. Note a sharp metallic rattle, slapping or scraping apparently at the front or top of the engine, near and along the timing cover. When the oil pressure is low during cold start it is usually loudest and it can go a few seconds. This rattle could be persistent, even during idle or at low RPMs, the higher the problem is. This sound is usually a sign of a loose chain because of a festering tensioner or worn guides.

2. The Illuminating Check Engine Light (CEL):A defective timing chain system does not last so long silently in the electronic shops. The CEL will most probably turn on. Possible trouble codes associated with timing problems are:

P0016, P0017, P0018, P0019: These suggest a correlation issue between the chain shaft and camshaft- this is basically saying that the chain no longer perfectly synchronizes the crankshaft/camshaft position anymore.

P0008, P0009, P0011, P0012: These usually concern that camshaft position timing is out of sequence, possibly as a result of chain stretch on variable valve timing systems.

You never want to disregard these codes. You have a friend, diagnosed using a scan tool.

3.A stretched chain disarranges the engine dance which has been so carefully timed. You may experience such symptoms:

Rough idling/ misfires: The valves are not opening/closing at the appropriate time.

Lack of power or hesitation:The efficiency of the engine drops catastrophically and timing becomes erratic.

Low gas mileage: The engine has a difficult time in working at an optimum level.

Stalling: Extremely poor timing will cause the engine to stall.

2. Get Professional Diagnosis Immediately:Failing to act upon early warning leads to internal damage being speeded up inside the timing chain kit itself. Though you may be unable to visualize them without disassembly, they in their turn lead to dramatic deterioration of the external symptoms:

1. Stretched Chain: This lies at the heart of the failure. The chain literally extends with time and stress. A prolonged slack chain does not have the ability to remain accurate and its performances grow wilder and eventually evolve to skip teeth.

2. Worn Sprockets (Gears): Chain rides on sprockets which are located on the crankshaft and camshafts. Tearing and wearing of the chain speeds up this wear on these sprocket teeth. Teeth that are worn may look or appear hooked and poorly mesh, which ultimately adds to the chances of the chain jumping or skipping.

3. Broke Guides and Tensioner: The guides made of plastic or composite materials prevent the chain to deviate, and the tensioner permits it to stay tight. Such are typical points of failure. Guides may crack or break or wear away altogether. There are possibilities of oil-pressure loss, leakage and due to overuse, the tensioner may wear out. Chain can crack anyway due to the loud noises created when guides fail causing whipping and excessive wear. Failed tensioner can give slack which is dangerous.

4. Maintain Oil Changes Religiously:The timing chain tensioner lives on clean oil at the right level and viscosity and lubricates the timing chain and guides. One of the main reasons that lead to early failure of timing chains and tensioner is failure to follow recommended procedures when changing oil. Adhere strictly to the oil change, as recommended by the manufacturer, as well as the type of oil by your manufacturer.

Conclusion:

Your timing chain is essential and obscure. Live with it and listen to the rattle, pay attention to the check engine light, and wait until there are performance losses. These are the death throes of your engine, in their last gasp so to speak before a timing break is irrevocably brought on. The failure to pay attention to these results in the internal deterioration of the kit and further, the disastrous failure of the engine. Repair should be a priority once there have been early signs of trouble, avoid aggressive driving and make it a point to start an early professional diagnosis. The most effective measure you can take is oil change. Taking action will save your wallet and your engine the worst damage.
