What is a VVT sprocket?
Located on the camshaft, VVT sprockets (also known as cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency. Remove the entire camshaft.
When should a VVT be replaced?
What common symptoms indicate you may need to replace the Variable Valve Timing (VVT) Solenoid?
- Vehicle gets poor fuel economy.
- Engine performance is diminished.
- Check Engine light is on.
What’s a VVT sensor?
Variable Valve Timing (VVT) systems are designed to reduce emissions and maximize engine performance and fuel economy. Variable Valve Timing (VVT) systems utilize oil pressurized solenoids and camshaft phasing sprockets to change the timing of a valve lift event throughout the engine RPM range.
Can a VVT sprocket be replaced on a Ford 5.4L?
Replacing the VVT sprocket on a Ford 5.4L engine is an in-depth job. This video shows you how to replace it correctly. If you’re replacing the VVT sprocket, our master technicians recommend replacing the VVT solenoid, too. Here’s what you need to know for both jobs:
When to remove the VVT actuator from a camashaft?
DON’T FORCE ANYTHING and remember that as soon as the Timing Chain is finally on the sprockets and the New Bolts (cannot re-use the old sprocket bolts) have been “Torqued to Yield” with the Torque Angle Meter… then the above tool should be removed before you forget it is attached at the back of the camashafts “Chance Favors The Prepared Mind…”
Do you have to pre-load the VVT actuator?
The New VVT Actuator must be PRE-LOADED by slightly turning the unit Clockwise and NOT FURTHER or past the Internal Stop… as it can be damaged.
Where are the VVT sprockets located on the engine?
Located on the camshaft, VVT sprockets (also known as cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency. To ensure proper performance for this
When to replace a variable valve solenoid ( VVT )?
Now that you know what all symptoms indicate variable valve timing solenoid failure, you must also know that it is imperative to replace a faulty VVT solenoid. Once you have diagnosed a problem in the variable valve timing solenoid, it is best that you either get it replace or do it yourself.
When to delete variable valve timing ( VVT )?
Eliminating the VVT system is required when swapping to a non-VVT camshaft. These cams offer higher valve lift and longer duration for more performance. A VVT delete kit removes the VVT components and replaces them with standard parts. At a minimum, they include:
Do you need to delete the VVT system?
If you want high performance from a bigger cam, you will need to delete the VVT system. (More on that in a second.) Engines with VVT will have a camshaft phaser actuator on the timing cover.
