Today I was just servicing up the motor in my mini, cleaning up the actuator bollocking around etc, I just pulled it out to cheack conition of the rod etc, and the thing seemed to "sieze". I took the end of the turbo to pieces (where the lambda sensor goes) and the waste gate cap had fallen down inside the manifold (exhaust, no turbo!)!!! the offending item looks like the bottom of a valve, and has no way of fixing it to the waste gate lever arm, or what was holding it has fallen apart!!!!!!!
can anyone tell me what has happened and how to fix it, the only way I can see of, is to weld it back on!!
how are they fixed on in the first place???
any help much appreciated!!
