The VVT or variable valve timing is and always will be one of the most noted breakthroughs in the history on automotive innovation. In modern cars VVT systems are used for improve performance and fuel economy by altering the valve lift event. This is what allows just the right amount of oil supply, this allowing the engine to give great and fuel efficient performance. It is a system that uses electronic technology to apply variable electronic systems through a variable valve timing solenoid. In case this VVT solenoid goes out of order, improper lubrication can cause a lot of damage and disruption to the gear and the timing chain.
