  • Need ABY wastegate it´s not sealing with the EM.

    Hi All,

    As per title my wastegate isn´t sealing properly with the exaust manifold letting pressure pass by, it´s ok where it meets the EM but the gate isn´t sealing and is wasting boost, everything else is ok, the menbrane is ok also.

    Is there any way to repair it?

    Anyone as a wastegate he is willing to sell?

    Thanks in advance for your help!

    Both faces must be flat and smooth - if you have chips or scratches or corrosion you will need to machine it. (Wastegate and/or manifold).

      Thank you for the reply, I haven´t taken it out yet but it looks like I have some play sideways in the shaft and I´m guessing the gate is worn a bit I was wondering if it had some kind of seal or ring like the ones in pistons!

        The valve shaft wears over time. You could look at placing a bush in the body and machining it to accommodate the valve shaft. Probably easier to find a good condition replacement
