Wastgate

The original wastegate was in quite rough condition. It needed quite a bit of work, although we managed to save it.

The valve seat was recut, a crack welded up, and the old bolts removed. I used stainless bolts now, to prevent rust seizure.

Heat distorted the mating surface. 

I skimmed it by hand.

Assembling the unit was a bit tricky, but with the right tools, nothing is impossible :-).
