That's bad news Bob, I had the same thing happen to my "S" after only
about 5 races on the engine during which the crank was crack tested.
The position of your break sounds to be very similar to mine. I suspect
that it is simply a question of fatigue however I was very surprised
that the crack testing showed no signs of problems.
See you at Summit.

Subject: 100 broken crankshaft - two questions
During a short ride, just as I was thinking how good the healey was
running,
a deep clanking suddenly started. Oil pressure dropped to about six
pounds and
I shut down. Dropped the pan last night and find the crank shaft has
broken
in two right across the throw behind the center main bearing. Haven't
removed
it yet but the break appears to be straight, and in the center of the
throw.
Question 1: Is this common or uncommon and what could cause it?
( Everything except the crank was replaced on rebuild eight years ago.)
Question 2: Anybody have, or know a source, for a good used crank?
Leaving tomorrow for Summit 2004 in Glens Falls, NY so I may not be able
to
respond to your responses too quickly. But any and all input will be
appreciated.
Bob
