How does the timing chain get lubricated?
The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.
Why does my timing chain not tighten when I Turn Off the engine?
The oil filter they designed for the engine also has a specific anti drain-back valve and for good reason. With a substandard oil filter the engine oil may drain back to the oil pan when the engine is turned off. A lack of oil pressure means the tensioners cannot immediately tighten the timing chains on startup.
How does oil pressure affect the timing chain?
Because of the length of the chains, guides are needed to reduce movement. They also use a hydraulic tensioner to keep each chain tight. Oil pressure moves the tensioner which controls slack in the timing chains. These components rely heavily on proper lubrication from the engine’s oil.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
Why are the plastic guides on the timing chain so long?
Because the timing chains are so long, they are supported by plastic guides. The timing chain is kept tight by force from the hydraulic tensioners. With the proper lubrication and the right oil filter this works very well for a great many miles.

Why are timing chains so important in a modular engine?
Why the proper oil is so important. The modular engine is an overhead cam design. Two very long timing chains keep the camshafts in time with the crankshaft. Because of the length of the chains, guides are needed to reduce movement. They also use a hydraulic tensioner to keep each chain tight.
