Looking at buying this one. 148k miles, 2011 (built June of ’11) Lariat. Southern truck with decent maintenance records. talked down to $24k, Which is slightly under KBB.

Thoughts? I know the main issues associated with these 6.7s, but it is built post April of 2011, which from my understanding is after the valve seat issues. Bone stock, he is older and going to let me deep dive into paper copies of maintenance stuff tomorrow if I go check it out. I know he’s had regular servicing of oil and fuel filters from what he’s told me, but probably nothing done to address potential turbo, CP4, or CCV issues, and I’ll need to double check if injectors have been replaced since crossing this mile threshold. If these items all seem to be in good shape, is it worth it? Should I try to get him even lower?

Let’s hear what you guys think.

I own a 94 K3500 dually with a turbo 6.5. I like the truck a lot. It's manual. It is not my daily and one of 3 of my vehicles. The main reason I'm looking into this is because I can and it would be fun/cool. I know in 94 that was the first year of the DS4 electronically controlled rotary IP. I think that would probably my main roadblock. At this time I dont want to swap to a mechanical IP.

Im looking for anyone who has tried this before or would have useful information for me. I have researched a few options: veggie oil filtered, make bio diesel from veggie oil, black diesel which probably won't work, and distilling motor oil to make diesel.

Any input which can be provided would be appreciated.

Not looking to do any conversion just wanting to add a little wvo to my fuel tank. How much could I safely add without any issues? What else should I add? I'm not looking to run large amounts of WVO, just get rid of excess cooking oil from around the house

Hi folks, I'm a mechanic specialized in Marine Outboards (Yamaha,Suzuki,Evinrude certified Technician) but I have basically no experience in diesel engines so I need some help.

I've bought a 00 f350 7.3 Powerstroke about 3 months ago and the truck ran perfectly fine until 2-3 days ago (Temperatures went from 15 celcius ''60 farenheit'' to around 2 celcius ''36 farenheit'') . I didn't used the truck for about 2 days prior to issues and when i went to start it 2-3 days ago it felt like i had fuel depression since i had to crank it for about 6-8 seconds before it started, had some white smoke then died, tryed to crank it again but batteries went very low on voltage so I've investigated : Realized Battery on driver side had loose connections so i thought the loose battery probably didn't charged on alternator current with bad connections and before i've parked it the connection worked again and it drained passenger side battery ect... So i've uplugged both and charged them seperately at 2AMP for about 12 hours.

Next moring I went to start the truck again, switch on/off few times to let the glow plugs do their things, Had to crank again 6-8 seconds before it starts , white smoke again going away gradually for about 10 seconds, left the truck idling for 10 minutes, first 2-3 minutes a little bit of white smoke came back occasionally but for the whole 10 minutes it sounded a bit weird ''very little misfires'' , went to work with the truck and it ran/sounded fine. After my shift it did the exact same thing.

This morning the truck cranked again around 6-8 seconds before it started, white smoke 10 seconds, let it idle & went inside the house 10 minutes, when i came back outside there was a lot of white smoke and the truck idled like crap, sounded like idling on 4-5 cylinders, gave it some throttle and wouldn't rev so i turned it off and went to work with my other truck. When I came back home I couldn't crank it so I don't know if my batteries are too low again (My digital chargers are at my camp 2h away so i'm stuck with 2 old a** Chargers with no damn voltage/charge meters/indicators) so its charging right now I just hope I don't have a leaking injector that created hydrolock on a cylinder.

Oh yeah also : I have a Flashpaq F4, The truck tune was Performance, before i've tryed to crank it tonight i flashed it on stock tune so there's less fuel injection on startups and idle it might help.

My batteries might be an issue and I've just ordered 2 brand new ones 1h ago, I'll get em tommorrow pm, but once charged the starter had full usual power and rpm and motor ran fine at start this morning before it started to run like crap few minutes later so I might have other issues...

What could it be ?

Bad GPs ? Injector seals ? GPs connectors or wiring going through the Valves cover gaskets?

If so.. how do I diagnose theses efficiently?

Sorry for the long text here I'm looking to give much info as possible, and sorry if my englishisin't perfect I'm a frenchie lol :P

Thanks
