For the automotive, truck, and heavy equipment industries, I would
like statistics on the failure (most likely cracking) of cast iron
exhaust manifolds and cast iron turbo manifolds due to temperature,
but not for any other reasons such as vibration.

I would like to have the statistics (separate statistics for cast iron
exhaust manifolds and cast iron turbo manifolds) broken down by year,
that is, something like x% fail within 1 year, x% fail between 1 and 2
years, x% fail between 2 and 3 years, etc.  If possible, I would like
to get both industrywide information (for each of the auto, truck, and
heavy equipment industries) as well as data broken out into specific
major companies in each industry (such as GM, Ford, Caterpillar,
etc.).  I would like this data for the United States as well as
worldwide, broken down by general geographic region (i.e. Europe,
Asia, etc.)
