In this image, you can see a seal plate with the tell-tale signs of corrosion damage. On a new, undamaged back plate, the surface would be smooth, but here, corrosion has caused the face of the seal to become pitted, worn and roughened.

This example illustrates the damage that can be caused by inadequate or faulty air filtration. It’s a common problem and in these examples, small pieces of dust, dirt and grit have been able to enter the turbos on the air inlet side.

This is a common problem with turbos that are attached to pieces of equipment that are stored outside, like marine turbos and those attached to outdoor generators.

Here, you can see three compressor wheels with varying degrees of damage to the blades. This kind of damage is fairly common, and caused when a foreign object (like a stone or piece of metal) enters the compressor on the air inlet side.
