Bad News. Spun a rod bearing in my motor and it eat up the crank and the rod. There is metal in the oil and in the bottom of the oil pan. Tried to order fresh motor from local dealership but they said its dicontinued. I was wondering whats different between a typhoon motor and a new 4.3for say a 98 Jimmy, besides turbo and all that off course. The internals, externals is anything the same or different? Thanx
