ENGINE VARIABLE VALVE TIMING (VVT) SOLENOID
Brand Information
SCHNECKE
- Provider of ENGINE VARIABLE VALVE TIMING (VVT) SOLENOID products to the worldwide OEM market and aftermarket.
- SCHNECKE offers complete ENGINE VARIABLE VALVE TIMING (VVT) SOLENOID coverage for Asian, Domestic and European vehicles.
Variable valve timing solenoids (VVT) are an electromechanical device that control oil flow to the engine’s cam timing system. The powertrain control module (ECM or PCM) sends electrical pulses to an electronic solenoid that will move the mechanical portion of the VVT system depending on engine load and speed. The VVT system can advance or re-tard cam timing by altering the duration of time the valves stay open and valve overlap (time the intake and exhaust valves are open at the same time), this will give the engine the best possible performance, fuel economy, and lowest exhaust emissions under all operating conditions.
For the VVT to properly perform it is imperative that the motor oil condition be clean, be at full capacity and be of the proper oil type for the engine application. The VVT system requires proper oil pressure and viscosity to work correctly. If the oil is contaminated or low when the VVT is commanded to move there will not be enough oil volume to change cam timing and a trouble code will set. Located on most solenoids are screens, or filters, which protect the solenoid from internal damage due to contaminates. Following your vehicles recommended maintenance schedule is imperative for extended life and wo-rry-f-ree operation.

The gaskets for this are 1.75 inches and way too big for what's needed on the 5.4. Now I have to wait for a refund and order another set and wait another day for the correct gaskets to arrive when the system said it fit. Ughhhhhhhhh!!!!

Unlike the OEM Camshaft Solenoid Timing actuator, the screw on these is NOT permanently attached to the actuator for safety. It's absolutely possible for the screw to pop out of these knock-offs and fall into the engine ... which is what happened to me. Not worth the cheaper price.

My 2004 F-150 5.4L check engine light came on and needed new solenoids. So thought I would try these. I swapped them out and it did the job. Check engine light is off. Word of caution though: These are not threaded on the housing for the Allen bolt as the authentic Ford Motorcrafts are. So when you're screwing these in, be sure to keep pressure on the bolt with your screw driver so you don't lose it in the head. Because if you can't get it out, you're going to have to take the valve cover off.

They are parts for my truck that started running bad. They came packaged well and they are very well made. Great buy for the money.
