Question

What is the average time to replace a Variable Cam Timing Solenoid in a 2008 Ford F150? How often do they go bad?

Answer 1

The most possible cause is dirty oil or wrong oil weight I would replace the oil if you have not replaced it in the last 4k miles and use the correct weight of oil.

I don't see book time, but I don't think it's more than 1 hour
