How does a timing chain guide Bolt work?
Innovative fix – this engine timing chain guide bolt allows for simple replacement of a sheared original bolt Saves hours – reduces repair time dramatically by eliminating need for head removal, drilling and tapping Integrated design – plug and bolt combined as one piece to easily restore functionality
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.
Can you replace a timing chain without timing the engine?
Articles on the internet state, not turning the camshafts or crankshaft allows replacing the chains without timing the engine. This is very dangerous at best and may cost an engine. It also fails to recognize cam timing is already off when a guide breaks.
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.
