Ok here's the story. My best friend's brother in law went to Phoenix, with his father in law( also my best friends father in law) to buy a flord powerjoke. The brother in law called me saturday night and asked whether or not they should buy the flord. Now Phoenix is 600 miles from here and they went there just to buy this truck off ebay. So, why did he call me? He wanted my advice on white smoke, cause this truck was blowing white smoke. I said, just walk away, you don't want it, it's bad and expensive to fix white smoke. They didn't listen. So of course I get a phone call sunday night. "We made it home, but it died twice on the way, i'm taking it to the ford dealer tuesday". He called me today, the engine is dusted. Someone, at some point ran it without an air filter. Total for an overhaul on this powerSMOKE? $11,000! They only paid $14,000 for the whole truck! I said "did you get a warranty from the used car lot"? "Nope". DOH! Does anyone know if these engines have liners, or do you have to bore them out? Does this O/H price seem high? Hell you can get a series 60 overhauled for 11,000 bucks. After getting off the phone with him today I went out, pulled my BHAF off, shook the dust out, then got the shop vac and vacuumed the filter out and made sure the fittings were all tight. Just thought I'd share that with you guys. Diesels don't like dirt.
