C12 engine, absolutely no blow by. No oil leaks. Just serviced and inspected in PA, sticker good to 5/16. Good brakes and tires, all aluminum wheels. One air horn is broken, but the other still works as it should. Only selling because one of my accounts just got stolen away by another company. I had intentions of sandblasting the frame and painting before winter. But it"s not rotted or anything anywhere. Didn"t want to just throw paint over it to mask it for sale. I"d rather you just see exactly what you get, and it really isn"t bad. Used to have a blower mounted for bulk tankers, blower removed but PTO still on trans, easy install for a wetline. Alternator hub squeals a little, thats the only complaint I"ve had from the driver. Drives very straight and quiet down the road. Hood is cracked up a little and closes a little funny if you aren"t level, and bumper is bent. Other than that totally solid unit ready to work.
