Car is 2010 supercharged Roush, 4.6L 3V, 24psi boost, 625rwhp. Earlier this season, I went for a ride and noticed an engine noise. When I revved the engine a little bit, it sounded like a chain was rubbing against something, so I immediately suspected a broken chain guide.
So I bought new Ford timing chains, heavy duty MMR guides, along with two new Ford phasers, and two cast iron tensioners. Heck, I even bought a new timing chain cover, cause it was so cheap, haha.
Anyway, I take off the timing chain cover and I see no problems at all. Nada, the chains and guides are perfect. Tensioners and phasers, I'm not sure. I'm gonna replace all these parts anyway, since I already bought the stuff.
My next suspect(s) is a valve spring. Maybe a broken valve spring, or possible a rocker?? Any thoughts are welcome. I'm kinda stumped, and worried........... Thanks![beer :beer: :beer:](/styles/default/xenforo/smilies/beer.gif)
