Big,

We've had aluminum auto engines without liners and as I recall they
had a pretty high cylinder failure rate?


Can you explain further? Are the engine blocks aluminum on the
Bombardiers? That's quite common in the auto industry, isn't it? Also,
do you have the feeling anything could be much worse with regard to
premature cylinder problems than current TCM/Lycoming stuff?
