engines

[sunnysky]

Hmmmnnn. makes me nervous too, when Continental factory engines are making 7 hours.
My present engines run great, with good oil pressure and cool temperatures after almost 1700 hours when we became aware the airmelt/var crankshaft issue. Thats the only reason for new engines as on the U.K. register we can run on condition on a private CofA. unless there are such AD's.
One final thought. My engines are on their first run. There must be many engines in service with airmelt cranks with thousands of total hours on the cranks which were "overhauled" before the AD and with less than 1500 hrs now ? Any ideas why this AD was issued? I have never heard of many crank failures on these sturdy engines.
