so Ive followed the site for a couple years now, through a couple formats and just now getting to my first post. I've got a high pitch ring between 2100 and 2600 rpm whether driving or in neutral. took the skid plate off to make sure that wasnt it. sounds like a loose washer rattlin around and arond but cant find one. Its a 2.7 and the local import guy thinks could be a broken timing chain guide? any thoughts or anyone else delt with this? I'd appreciate the input.
