7.3 misses

Hey everyone. I was wondering if anyone has heard of problems with 7.3s missing. I am looking at a 1994 F-350 with a 7.3 IDI turbo diesel. The pickup has 200,000 miles on it, but the motor only has about 100,000 miles. The person is asking under $1000 dollars for it, and the Dana 60 frontend in it is worth more than that. I talked to him about it a while ago and I was looking into putting a Cummins into it anyway, so I do not remember for sure what was wrong with the motor. I am pretty sure that he said that it was not firing on one cylinder. After thinking about it, I decided that I could attemt to fix the motor and try to sell it for a profit. I was curious if anyone out there has heard about problems like this with the 7.3. I will talk to him as soon as I can and get the whole story.

It could be. I need to get a better description of what is wrong with it. The guy who owns it was fed up with it and bought a Dodge diesel. I do not think that he tried to figure out what was wrong, so it could be something simple like that.

It's a bad fuel injector. The 99-01 7.3's are notorious for it.....mine has blown 6 in the past 3 years.

If it is missing at idle you can go around to each injector with a 5/8 wrench and break the connection loose and see which one doesnt make a difference. that will be the bad cylinder. It could also be a bad valve bridge broken under the valve cover. Get back to us with your findings.

Yeah, I'll check that out when I have a chance. I am going to college about 350 miles form home, so I only get home every 2 or 3 weeks and I usually don't have much time to do anything when I am home. I think that if I do get it I will probably either fix it and try to sell it or part it out if the motor is bad. It is not too difficult to put a Cummins into it, but it will probably cost $3000 or more to do the conversion, not including the cost of the motor, so I might as well buy a Dodge and skip the hassle.
