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.)

After this information is found, I would like information on annual
warranty expenses incurred by companies to replace cast iron exhaust
manifolds and cast iron turbo manifolds that have failed due to
temperature, but not for any other reasons such as vibration.  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.)  Again, separate data for cast iron exhaust
manifolds and cast iron turbo manifolds.
