How to fix a chain driven V8 timing system?
There are several approaches that can be taken when addressing the repair of this chain driven V8 timing system. Option one, which the RSW Service Team suggests if the owner intends to keep their vehicle in-definetly, is to complete a FULL replacement of all associated components with the updated parts from Audi.
What causes the plastic on the timing chain to break?
When this occurs, slack in the chain tends to jerk and the plastic timing chain guides can break. We see many Ford modular engines with broken timing chain guides. The first symptom is usually a rattle on the start up. Because the timing chains are so long, they are supported by plastic guides.
Why are my tensioners not tightening my timing chain?
Problems begin when improper viscosity oil and substandard oil filters are used. 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 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.
Are there any Ford primary timing chain tensioners?
These are Brand New OEM Ford Upgraded Iron Primary Timing Chain Tensioners. These Tensioners feature a Fixed Racthet System that never allows the chain to loosen. This can be an extreme benefit if there is ever a loss of oil pressure. Write the First Review!

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.
