well im going to look at a pete tomorrow with a isx. what are your reviews of the isx ? my family runs all c15's and detroit s60. what real bad about 2005 cummins isx motors? thanks.
I had a CM870 (EGR) Cummins ISX in my '06 379. Ran great, got better fuel mileage than a Cat, but be prepared to replace EGR valves/coolers once every 1-2 years. Or I hear there are things you can do about the EGR problem that solve it permanently but aren't okay to discuss here.
Heard about the liners dropping and causing head gasket and other problems. Also i was talking to an owner op at the Beacon who said he had his fuel pump replaced bc it had porcelain internal parts. Cummins started a recall bc in would desenigrate and destroy the motor they started to recall for awhile then stopped honoring it. Change the turbo after abt 300,000 miles and egr every year
i shouldve told you guys this. This is what i need real advice on. its a 379exhd with a cummins isx. the guys a dealer and he says it has 480,000km original so around 300,000 miles. he said the truck ran a belly dump and only in summers for gravel. it has a automatic lol im thinking of converting to 18spd. it doesnt have a clutch but my uncles added a clutch to a auto c
converted it to a 13spd. the thing is, is this truck for real good or what. is he lieing? 480,000 km original. he's asking around 30k CAD only. its 4 hours away from me though. is it worthit?
480,000 sounds about right if it only worked summers hauling locally. My dad owned a brand new '07 T800 with the pre emission ISX 530. It only really had like 2 egr valves and the turbo changed in it over the year and a half he ran it (All warrantied). He said it pulled better and burned less fuel than his old '03 T800 C15. They all have their issues but if the rest of the truck has been looked after and everything looks mechanically sound and clean it might be a good deal.
That tranny swap is gonna cost a lot in just parts and we'll assume you'll do the labor, if not then you might wanna just but a truck that you have to limited modifying unless you have deep pockets then go for it.
