Yesterday, while checking over my engine
for the source of a nagging oil leak I found a broken tension
bolt, I guess it’s good in respect to finding the problem but
WTF?
During installation I applied a spiral of
silicone around each bolt trying to prevent this from
happening. The broken bolt is positioned in the upper left
hand corner (if viewed from prop end) and according to my
Haynes Manual it is either #8 or #12 in the torque-sequence.
Checking Tracy’s website I read about his
SQUAWK with same issue many years ago … he was able to get the
bolt’s threaded portion out without having to tear-down the
engine or resort to the drill and easy-out method.
What happens to those metal shavings inside
there if I have to drill and use an easy-out?
Can I extract them all with a magnet or
compressed air?
Am I looking at an engine tear-down … or
replace the bolt (or bolts), re-torque the stack and carry on?
