A friend of mine has a 1996 2500 with the V-10. About 2-3 weeks ago it started missing on him so he took it to the dealer. They told him that the engine had dropped #6 & #9 cylinders. They sent the heads off thinking it had cranked the head. Head was fine. They called him yesterday and told him the problem was in the lower end with a repair estimate of $6,000 to $7,000. What is up with that? Anybody have any ideas or dealings with the V-10?
