I was told that the late model 3350 used ceramic coated pistons and combustion chambers - is this true? If true, which model, and when? Is there a good book on the 3350 ? Questions, Questions.

I'm not aware of ceramic coated pistons or combustion chambers but I believe parts of the exhasut system may have been ceramic coated.

No one to my knowledge has written a book dedicated to the 3350 - wanna give it a shot?

I wish Kevin Cameron would author a book on the Wright r-3350. Judging from some his columns in Torque Meter he has done research on the subject and he has the necesary writing skills but I supose he is kept busy writing for Cycle World magazine.

The piston domes of the 988TC18Ea series were nickel plated to reduce the effect of lead bromide attack. This information comes frpm a Wright Company publication titled "Details of Design Features of the 3400 HP 988TC18EA series Engines" Carl

I have a flight hood (covers and ducts the exhaust and turbine cooling air) from the power rrecovery turbine. It has a greeen ceramic coating on the external surfaces, however I'm not sure if thiis is a"factory" coating or a "modern" update. Interstingly, the flioght hood is considered and arofraem component, not an engine component.
