<p>[QUOTE="cliffster21, post: 4600049, member: 115474"]earnies, </p><p><br /></p><p> First of all, I am very sorry to hear about your mother and I offer my condolences. I thought I would chime in here because last year I bought a 2007 International 9400i 72" sleeper with ISX and 730,000 on the odometer. I like the truck overall and was surprised at how light it is. I pull a 48' combo flat and my truck and trailer with me in it weigh about 30,300 (no apu). I am also pleased with the fuel mileage I have been getting. I am able to get right around 7mpg average. I am a slow driver however, going 60-62 and letting all the super truckers blow by me. I think it is funny that the guys who really should be driving the aero trucks because they like to run 75 mph won't touch them and swear by their dual stacks, dual air cleaners and 18 speeds. </p><p> </p><p> Based on my experience I would give you these suggestions when looking at a truck with an ISX. Make sure you get good maintenance records for the truck. Take it to a mechanic you trust and have them take off the valve cover and look at the valves and the cam. If you can afford it, have them drop the pan to look for metal shavings and take a look at the main bearings. I have learned the hard way that ISX's are infamous for toasting camshafts. I have spent the last two weeks at the house because when I took my truck in for an overhead, they found that the injector cam was pitted and scarred on three lobes. The mechanic said it looked like the oil passages got blocked and starved the cam of oil causing it to overheat. When the cam overheated it spun three bearings and ruined the cylinder head. I also had them replace the main bearings, because they were worn when they dropped the pan and checked them. The truck currently has 800k on it. When you look at the maintenance records, make sure they weren't doing extended oil changes. Cummins recommends 25,000 miles, but I think that is too much, especially with that EGR valve putting soot into the oil. One good thing about my truck is you can unplug the EGR and the engine doesn't derate, you just get a fault code. I would recommend getting that EGR valve blocked off as soon as you possibly can, the engine will last a whole lot longer without it. </p><p><br /></p><p> This is just my .02 cents based on 10 months of running with my own authority with my 9400i. I would say no matter what used truck you buy you are going to have your fair share of problems with it. If you really check out the truck before you buy it, I think you can mitigate some of these problems. When I bought mine, I probably jumped the gun a little bit and should have waited until I had more money. Unfortunately I was very limited in startup money and therefore pretty limited in choices for a truck (bank would only finance 2007 or newer). If I had it to do it again I would check the truck out ALOT better and probably go with an older truck that had a recent inframe and some of the parts that start wearing out at around 650-700k replaced so I didn't have to do it all. Also look for a truck that was better taken care of.</p><p><br /></p><p> I hope some of this information helps you and wish you the best. I will say that even with all the problems I have had in my first year, and I have had a lot of issues with my truck I am glad I took the leap and would do it again. The freedom of doing it on your own is worth all of the headaches (in my opinion). Good luck and God bless.[/QUOTE]</p><p><br /></p>
