  • Turbo wastegate rattle?

    I'm getting a noise from turbo area when revs get over 3000ish, could it be a problem with the turbo or noise from wastegate, it's a high pitched, squealing noise that goes away as revs drop when truck changes gear.

    I've had this before when I replaced a turbo on a 3.0, it's the metal gasket between the turbo and downpipe. At around 3k revs there was a high pitched squeal, cured it by smearing exhaust assembly paste to both sides of the gasket.

      ah! Cheers Vince, I recently replaced the downpipe with a new one so.....I'll get the paste out.
      I thought it sounded like a leak.

        Mines done the same since the head change but I can't be bothered to mess on with it, I found a post saying what it was somewhere on here shortly after it began. H
