Default Is this an adjustable BOV or external Wastegate? (from a Mercedes)
I recently added this to my collection of parts in the garage. its off an 82 Mercedes but Im not sure if its an adjustable BOV or an external wastegate. The turbo was already gone so I never got a look at it. I think its a BOV just with an adjustment nut on top. Where that blue spot of paint is on the top is the adjustment nut.
Thanks for the help.

looks more like a wastegate to me. Solid, iron and carbonated.

Gotta love the carbonated wastegates, they are fizzier than the regular ones.

The long piece measures 1" and the carbon coated piece (with the 2 mount holes next to it) measures about 3/4"
