a series of unfortunate events: a p/s fluid leak caused an accessory belt to deteriorate. part of the belt came off and was wound around the crankshaft sprocket. it was pulled underneath the timing belt (different, much more important belt) as the engine rotated. the timing belt was then unseated from it's grooves in the sprocket, which caused the engine to jump out of time. later on, as the engine was being cranked for diagnostics, the mis-timed engine fired a spark plug in a cylinder that was on the intake stroke. this caused combustion to occur not only in that cylinder, but in the entire intake manifold. the large volume of combusting fuel air mixture then blew the manifold apart. all because of a power steering fluid leak that went too long unattended to.
the good news is: with some careful surgery tomorrow, this engine should be able to run again. oh, and a new intake manifold of course.
