Hey guys I work at a dealer and I do some UCI. Ive come across a 2005 eclb fx4 f250. I know quite a bit about cummins but im not well versed in 6.0s. I did the UCI on it, its very clean inside and for the most part around the engine bay. It only has 45,000 on it, was used as a tow rig for a camper so it sat probably half the year. From what I saw the turbo leaks oil, theres a leak at oil pan and it still has gold ford coolant. I noticed its completely stock, no deletes no nothing. The only thing im not sure of is if it was tuned, how can that be found? I can get it for around $17,000 the dealer is asking $20,000. Is this worth it?
