Chevy Impala Timing Chains, Gears & Covers

The operation of the engine powering your Chevy Impala is based on four strokes – inlet, compression, combustion, and exhaust. They take place inside each of the cylinders one by one, in a strictly determined sequence and with carefully set time intervals. However, apart from synchronizing with each other, they must also work in unison with the engine rotating assembly. That’s what the timing chain and gears are meant to provide. Since these are metal components experiencing friction, they need lubrication and are vulnerable to dust. That’s why the assembly is provided with a cover shielding it from the environment.

Although a chain-based timing mechanism is considered to be much more durable and reliable than the one utilizing a belt, it still has a limited useful life and will need to be restored sooner or later. A worn chain loosely sitting on gears will generate noise and overload the system while causing further damage. Which is why it has to be replaced with the first sign of a problem. A high-quality replacement will ensure the system’s reliable and trouble-free operation.
