Dennis,
Thanks for the flash point link. Good information.
My fire started only one mile into my trip to work on a chilly day. I
doubt the exhaust manifold had reached 420° or the flash point of motor
oil.
It may be that the failed breather o-ring was putting out a fine oily mist
at the time. There seemed to be a thick layer of gunk on the top of the
engine. I had 220# of sand and salt on my hatch all winter and hadn't done
an inspection all that time. Protocol updated ;-)
I'm still blaming a failed (Magnecor) ignition wire.
Happy holidaze everyone!
