I make sure on my 3.0L that I run the right stuff just in case; so it sounds like there might be a problem.
R U running the correct weight oil now ?
I'm in the same boat asyou as i do not as much about internal engine noises and the cam.
I currently run 5w 30 but now I'm running 5w 20 to help with the chirping. So far ok. Going to Seafowm tomorrow and add some Lucas to it. They suggested i run diesel oil but i do not know if i should or not. Just hoping it goes away so i do not have to replace the syncro.
Thanks for your help, I'll keep this thread updated as i go.
