Can I drive with a bad oil control valve?
If you push a vehicle with a bad oil control valve too far, you’re going to have to deal with more than just poor fuel economy and some decreased engine performance. You should, therefore, stop driving a car as soon as you suspect problems with an oil control valve and have it checked out by a professional.
How does a variable valve timing system work?
Most modern VVT systems utilize engine oil (hydraulic) pressure and some type of an electronic solenoid to initiate changes in valve timing, lift, and/or duration. One of the most common problems found when diagnosing a VVT system malfunction is low oil pressure or low engine oil level.
What causes a bad variable valve timing solenoid?
When the oil has a lot of impurities, it loses viscosity. This can also cause clogging in the variable valve timing solenoid system, thus also clogging the chain and the gear. If you see dirty engine oil, chances are that the VVT solenoid system is going out of order.
What happens if your oil control valve goes bad?
An oil control valve (also referred to as a VVT solenoid) is an important component of a vehicle with a variable valve timing (VVT) system. The existence of the system aims to control the performance of the engine utilizing two methods to retard and advance camshaft angle. If your oil control valve goes bad, you’ll have problems.
How does the oil control valve work on an engine?
Oil pan → Oil strainer → Oil pump→ Oil filter→ Oil gallery→ Cylinder head / piston → Crankshaft bearing Oil control valve commonly used on engine with variable valve timing system. This system is to control the engine performance using the method of retard and advance camshaft angle.
What is the advantage of variable valve timing?
Top 4 Advantages Better Engine Performance. When you put more demand on your engine, it needs to have more revolutions per minute (RPM). Better Gas Mileage. Without variable valve timing technology, an engine must work harder and consume more fuel just to satisfy the demands being placed on it by the driver. Reduced Carbon Emissions. Higher Engine Longevity.
What is a variable camshaft timing?
Variable Cam Timing. Variable Camshaft Timing (VCT) is an automobile variable valve timing technology developed by Ford. It allows for more optimum engine performance, reduced emissions, and increased fuel efficiency compared to engines with fixed camshafts.
What is variable timing control?
Variable Timing Control ( VTC, sometimes called Variable Cam Timing (VCT), or NVCS (Nissan Variable [timing] Control System or Nissan Variable Cam System) was the name given to the variable cam phasing system featured on the VG30DE(TT) and other similar engines from the era.
What is a VVT solenoid?
The VVT solenoid is the electrical part that gauges the engine’s needs based on oil pressure. It then accordingly controls the camshafts which are the mechanical parts responsible for opening and closing engine valves.
