    We have five 50SG engines. We are beginning to see a lot of exhaust piping leaks. We had one unit to break the piping support bracket to break in two. With the loss of the support the piping flanges sheared the bolts off, and caused the bellows to break. We’ve found the bellows broken on two units now. None of our engines have many hours on them.We’ve started using a thermal imaging camera to scan the lagging around the piping to pick up unusually high temperatures.  Are other users finding that exhaust leakage is common?
