My GP is an 05 GT, and whenever I apply gas, regardless of whether it is in gear or in neutral/park, there is a scratching noise coming from the front center. I can't completely say grinding because it doesn't sound like so, it's just a very weird scratching noise, very hard to describe.
The car acts normal, it accelerates fine and there is no handling difference, not to mention I've replaced both front LCA's, the right CV axle and wheel hub, new Dorman sway bar and bushings/endlinks. So I can rule out the suspension. And the fact that the noise is identical when the tranny is disengaged makes me think that it's either engine related or possibly belt/pulley related. I will try giving it some gas with the serpentine off today and report back on those results, I think it could possibly be the bearing going on my already unfunctional A/C.
The noise is almost like a squirting noise too, like oil, but I replaced my leaking valve cover gaskets and grommets within the last two weeks along with a full sea foam treatment, synthetic oil, etc. Full maintenance and the noise is still exactly the same.
I don't know, I'm stumped on this one, there's another rattle in the front right at any speeds over about 30 mph but at this point I think that's just a loose bolt or a rock in my fender or something. This noise is just really starting to make me nervous about the reliability of my car.
