While servicing my Volvo KAD42 service department discovered a hole in the exaust elbow. I had the elbow replaced 3 years ago. After removing elbow they discovered the turbo was rusted out and had to be replaced. Should the elbow lasted only 3 years? Why did the hole in the elbow cause the turbo to go.
