It is not the VCT system making the noise.... he needs to get his timing chain guides replaced RIGHT NOW!!!

NOW!!

Oh, I know, I have told him and shown him. He is saving now to do it.

All I know is when his truck has 5w30 in it, it makes a lot of noise, with 5w-20, it does not make near as much noise.
