Another post of unknown noise
Last Friday I bought a regular cab long bed 4x4 6.4 with 125k miles for 125000, today when I was driving it to work I started hearing a noise, and now I'm starting to understand why the lovely ford stealership had it so cheap, the sound anyways is intermittent, only happens under moderate acceleration and boost from 5lbs to just under 18lbs of boost. It about sounds like a bearing on the belt system or in a turbo going out. Sorry for not posting and videos I'll probably get them up sometime this week, but I figured I would go ahead and ask on hear for help because im 6.4 dumb. I have checked all my clamps and boots and my boost gauge doesn't flutter, truck is also completely stock, and never had anything bad on oasis, auto check, and car fax. Oh and also the radio won't turn on and I checked all fuses
