No, the Nissan X-Trail does not have VVT-i (Variable Valve Timing with intelligence) technology in its engine. VVT-i is a technology developed by Toyota to improve engine performance and fuel efficiency by adjusting the timing of the intake and exhaust valves. Nissan uses a different technology called CVTC (Continuous Variable Valve Timing Control) in some of its engines, but not in the X-Trail model.
It is a over head valve engine with a timing chain.
The timing chain is located under the valve cover on the passenger side of the motor.

Adjusting the clearance of a valve in a 4BE1 engine involves setting the gap between the valve stem and the rocker arm to ensure proper valve operation. This adjustment is crucial for maintaining optimal engine performance, as it affects valve timing and can prevent issues like valve bounce or insufficient sealing. Typically, this is done using a feeler gauge to measure the clearance, followed by tightening or loosening the adjusting screw or nut to achieve the specified gap according to the manufacturer's specifications. Regular maintenance of valve clearance helps enhance engine efficiency and lifespan.
