injector cups

My 99 7.3 was running very roughly, and quit. I had it towed to the local dealership. They had it for a couple of weeks and determined that someone had vandalized my truck by putting something in the fuel system ( they said it smelled like alcohol and looked like churned butter. I had the O rings replaced on the engine about a month or so before this happened, and it still had not been running exactly right. Anyway the dealership found injector #5 was stuck internally and leaking the high pressure out into the crank case (I'm reading this off of my invoice). They removed contaminated fuiel from tank, flushed lines and tank and cylinder heads, replaced the bad injector, and glow plugs 5, 6, 7, and 8. Truck smelled like diesel fuel when I got it back. I took in to a frend for something else about a month later, and had him check the smell too. He discovered diesel fuel in the coolant. I took it back to the dealership. I was told his was a new problem and that all the injector cups needed replacing. The truck has over 200,000 miles on it. Should this have been addressed when it was torn down the month before?

Ehh thats kind of iffy. The 99-03 7.3 injector cup are pretty durable from what I hear. Im not a mechanic, this just hear say. When I up graded my injectors I was told to just visually to take a look at them and stick my finger in them to check for cracks. If I found no cracks then I shouldn't worry about it untill happend. Injector cup sleaves are pain in the a** to replace from what I hear so figured I would cross that bridge when I came to it. In your case Im not shure of how they figure out just one injector is bad, like I said im no mechanice, but Im guess they can tell with out pulling all the injectors. So, If they only pulled the number 5 injector to replace it then they would have no idea if the other injector cups were bad. Then again, if they were bad at the time I would think they would recognize the signs of cracked injector cups (ex. fule in the coolant). I know it can be hard to diagnose everything wrong with a truck with multipule problems but I would say this is something they should have noticed. Im shure they felt like a Dumb A** when you brought it back and probabley came up with the excuse that it was a new problem. Thats my guestomation im shure someone one here can shed more light on the situation than me.
