My other cars with same engine were Buicks and oldsmobiles. This chain is much like a thicker version of a bicycle chain, which meshes with the crankshaft timing gear and camshaft timing gear.

Coolant in the oil will not cause a timing chain to break. They are, imo, 2 completely different issues. Usually, coolant in the oil is obvious, the oil looks like a green-brown milkshake.

If the oil looks normal, you may not have a leak at all. Imo have the existing engine oil analyzed by a lab if it looks normal to verify the condition. As for the timing chain In this case, a new chain and sprockets will put everything right.

If the chain really and truly has broken, then its likely one or more valves are bent, since they will probably have hit a piston. If this is the case, the cylinder heads must be removed and repaired. Pop the oil cap off, look at the rockers when someone turns the motor over Do the rockers move?

Does the motor turn over like it has compression? And did they replace the crank sensor? It is extremely rare for a timing chain to break or jump time on these motors, the Tensioner for the chain is pretty good and I have pretty much never seen a series II jump time.

What's imo?On most GM vehicles with V-8 or V-6 engines, a metal timing chain is used to connect the camshaft to the crankshaft. This causes the camshaft to move in synchronization with the crank, causing the camshaft to open and close the valves in the proper sequence and duration for the intake, power stroke and exhaust cycle. Because of this, pronounced slack in the timing chain can have a direct effect on the performance and fuel economy of the engine.

A worn timing chain introduces slack into the connection between the camshaft and the crankshaft. This causes the valves to open and close later than normal, resulting in reduced cylinder pressures and uneven firing of the fuel mixture.

This can be felt as misses and uneven idling. A worn timing chain may cause the cylinders to be unable to fully fill with a fuel and air mixture, reducing the amount of energy they can produce. This will slow down the response of the engine when the accelerator is depressed, and result in less power.

A timing chain that receives sudden damage or extreme wear due to overheating or lack of oil may break teeth off of the drive gears on the camshaft, or jump positions on the gears.

This can result in a severe loss of power, very poor idle, and the camshaft and crank becoming so far out of synchronization that the engine will not start. A clattering noise coming from the front of the engine can be caused by a loose timing chain contacting the timing cover, or slapping against the gears on the crank and camshaft.

A timing chain making noise like this is most likely near failure. A loud popping hear under the hood is known as a backfire. A worn timing chain can cause this by allowing the timing of the engine's firing sequence to become so out of sync that the intake valve remains partially open during the power stroke, allowing the ignited fuel mixture to escape through the intake manifold.

A worn timing chain can be diagnosed by using a timing light to observe the relation of the timing marks on the timing cover with the marks on the crankshaft balancer.

If the marks move back and forth in relation to each other instead of remaining in a steady position while the engine is running, the timing chain is most likely very worn.

Photo Credits rusty chain image by Leonid Nyshko from Fotolia.Located in the front of the motor, the chain is run through a series of guides, gears, and pulleys.

There is also usually a chain tensioner that has the critical job of keeping the chain tightened within a specific specification. Timing chains have made a recent resurgence over timing belts because the chains have a longer life expectancy. Well, most of them anyway. Like any component in your car a timing chain will eventually need maintenance of replacement.

Owners of vehicles with these engines, like the Buick Enclave, have experienced issue due a stretched timing chain as early as 40, miles. Intake, compression, combustion, and exhaust are the four stages of the internal combustion engine. In order to achieve those stages over and over again, pistons and cylinders have to move in unison with the precision of a classical ballet.

When the timing chain has slack it can throw the pistons and valves into more of an interpretive jazz dance. It sorta works at first … you know, in an artsy way.

But eventually pistons start misfiring, valve timing is thrown off, a trumpet player goes off key, and before you know it your engine is destroyed. Timing chain slack can be due to a defective chain tensioner, or the result of a worn out and stretched chain.

The most common cause of timing chain stretch is irregular oil changes. They lightened their stance slightly in with Customer Satisfaction Program which offered to reprogram the engine control module ECM in certain vehicles, like the Enclave. In NovemberGM released a special coverage adjustment C for timing chain wear in 2.

Recently, you took your vehicle to your dealer to have Customer Satisfaction Program performed. Your dealer reprogrammed the engine control module to prevent premature wear of the timing chain and the illumination of the Service Engine Soon light. Further analysis has shown that the reprogramming may not fully correct this condition for all vehicles; we, therefore, are providing you with additional protection for the timing chain.

Even though the engine design basically stayed the same, the coverage for Enclave owners was limited to the model year. Why so expensive? Additionally, a stretched timing chain will almost certainly damage other components that will also need replacement like cylinder heads, camshaft position sensors, O2 sensors, etc. Maybe you've experienced this problem. Maybe you're concerned you will soon. Whatever the reason, here's a handful of things you can do to make sure it gets the attention it deserves.

Major class action law firms use this data when researching cases. Their focus is on safety-related issues. The timing chain is the conductor, controlling the timing of all those moving parts.

The engine will start to misfire as combustion timing is thrown off. You might find metal shavings in the oil as small bits of the timing chain fall off or shavings accumulate as your camshaft gets scored by the chain.

It could also cause dreaded oil sludge. In the worst case scenario, pistons smash into the valves, bending them resulting in catastrophic engine failure. The most common codes owners see when experiencing timing chain issues are P and P Compensation was also offered to owners who already paid for timing chain repairs. OK, Now What?
