Steve, Oldmanmopar is right, "real trucks don't have sparkplugs"

I had a 99 ram 2500 cummins. Only had 115,000 miles on it and the water jacket cracked. Turn out some of them came with a block casted in Brazil. They have a big 53 casted into the bottom of the block. Happened right after spending $1500 on a new injector pump. Needless to say I went back to gas.
