So I'd been hearing a small exhaust leak since I upgraded to the x turbo so I ran seafoam through the engine to find it. No smoke along the entire exhaust nor the manifold however, I did notice a small amount coming from the external arm connecting to the wastegate... I really haven't had any problems aside from a slight overboost on occasion, but I hate to hear the fluttering next to fences and stuff... Is there a way to fix this leak? It seems that whole arm is assembled by rivets or similar so I wouldn't think there'd be a servicable gasket...

 

Any ideas from the gurus? I'm really quite frustrated...

 

What ended up happening with this issue?
