Hello Brain Trust:
The car lost all boost on passenger side again. The techs are revisiting the piece of metal that clogged in the turbo originally. A theory being floated is that maybe the exhaust manifold is coming apart. Does anyone have pics of the inside of our exhaust manifold, or have one off that they can shoot some pics with a borescope?
The metal piece that lodged in the original turbo has very little magnetism. However; speculation is it may have lost magnetism due to the high heat that runs through it. We are wondering if the manifold may be the source of the original piece of metal, and perhaps another piece has come off into the turbo again. They borescoped the valves and it all looks good. The motor sounds very good at idle and the techs doubt the metal ran through the engine. The techs were also very impressed with how clean the engine internals look and are very confident the engine is good.
Have any of you all experienced or know of internal parts of the manifold disintegrating? The techs would also like to know if welds could have come apart? It looks like the engine may be coming out again- ouch.
Any thoughts/comments? TIA guys!
Here is the pic of the metal piece that lodged in the original turbo that started the transplant.
