Since replacing the turbo heat shield I can now visually inspect the exhaust elbow. To that end I am no longer in blissful ignorance. As shown in the photo the weld is corroding. Hot exhaust gas meets cold sea water. I do not think failure is imminent but clearly Something needs to be done. I believe it is stainless steel as it is not magnetic. Not sure of the grade. I see various options: 1. Buy spare gasket or make one and remove the whole elbow and if still sound have the welds ground out and repaired 2. Buy a new one for about £500 Ouch seems excessively expensive, typical Volvo rip off 3. Have a new one fabricated in stainless.
Does anyone know what grade of stainless is best? Has anyone been down this avenue? Know of a good fabricator?
