Review on 🔧 Pair of VCT Solenoids 8L3Z-6M280-B 8L3Z-6M280-A for 2004-2007 F150 Mustang Sport Trac 3V 4.6L 5.4L, Lincoln Navigator, Mercury Mountaineer - Camshaft Variable Valve Timing Solenoid Replacement by Michael Ramu

Fuel consumption almost doubled and engine noise at idle stopped. Very hard work to install them. I had to remove the valve cover to replace mine. If you have large offset VTC bore seals, you're in luck, it probably takes 15 or 20 minutes to do the job. My setup included a very small gasket with a hole in the middle that required the valve cover to be removed. I was quoted a labor fee of $680 to install at a local shop, which is usually very reasonable in most cases, but in this case I decided to save money and install it myself.
