At 102,000 my 03 "blew up". I was going down the hwy at 70 mph when my engine started making all kinds of racket and died. I got out to discover oil/ diesel running out the tail pipe. Dealer says the injectors on #3,5 stuck open flooding the cyls with diesel and i really should replace all six. chrysler told me NO WARRANTY, so 4,000. 00 later i have new injectors only to discover # 5 is knocking. Dealer says flooding cyl with diesel washed oil out and scorred cyl wall/piston, they need another 12,000 from me. When you unhook the wire to #5 injector knock stops but then engine smokes like crazy, i assume this is because with the injector killed there is no pressure in cyl to keep oil from getting past the scorred piston?. I could barely come up with funds to buy truck and this has me over a barrel, looks like i will try to over haul engine myself [another mistake?] ANY ADVICE?
