The first Cummins engine I've had to replace
in all the time that Dodge has built them. The first ones were in 1989 (I bought one) and now I've had to replace a shortblock in one because it was knocking. This is only the second engine I personally have seen that has needed to be replaced.
But if you go to the Ford dealer they have trucks lined up in the back lot waiting for engines. Yet people still think those Fords are the best thing since bottled beer. I'll never understand.
