I lost my #4 EGT probe at 11.9 hours TT, just got the replacement in today and I'll install it tomorrow. These are the Dynon probes, and they are mounted very close to the exhaust flange so I'm seeing EGT's in the 1400-1500 range. I know these probes have finite lifetimes and are a normal "wear and tear" item but I would not have expected a failure this early.
I'm going on the assumption that I've got a statistical anomaly on this one, but what it is the expected lifetime of these probes?
