6.9 idi 40 degree cold start on WMO (used oil)

Cold started my truck after filling it up with its first tank of homemade fuel. I filtered the oil to 5 microns and mixed it with stale gas. Overall it runs good but is definitely a little harder to start than it is running diesel. It’s probably 85-90% oil and 10-15% stale gas. It could definitely use more gas in the mixture.
The truck has new zd29 glow plugs. I used the 6.9 glow plug relay and a button that was already there when I got the truck.

Good to see someone making use of alternative fuels. I ran my '46 Ford Jailbar on diesel for 18 years. never had a problem.

[@jamesaucutt8284]

I like those 6.9 and 7.3 IDI diesel. Those were the best engines Ford ever used.

[@idahopotato5837]

Start it on diesel with the front tank and run oil in the back mixed with a bit of diesel for viscosity.

[@thequestionablecraftsman]

Unfortunately the truck only has one tank (previous owners doing not mine). I intended to get a 32 gal rear tank for oil and use the front for diesel but ended up selling the truck

[@AnimalKnowlege123]

Smart, and when parking park with diesel in the fuel lines just swap tank 1 minute prior to stopping

[@noah_loans]

@@AnimalKnowlege123whats the reason for running oil for 1 minute before shutoff?

[@AnimalKnowlege123]

@@noah_loans just read what i had typed. I meant the other way around! Start stop on pump diesel and then use motor oil for driving in between. When u go to park for a long time it will clean the oil out of fuel lines

[@noah_loans]

@@AnimalKnowlege123 oh so leave diesel in fuel lines? I just got a 6.9 . My first mechanical diesel. Have owned 2018 cummins and 2020 ford f450 but i never maintenanced those myself. So im trying to learn more on these old reliables

[@j.ongman5512]

thats a beautiful thing

[@TheBlacknightgang]

Try holding the throttle down half to full when trying to start it might start faster

[@ethanthedriver]

Ya bud😂

[@impactodelsurenterprise2440]

Why not full throttle?

[@nspro931]

Each time it took off and gained RPM you could have kept it running by keeping your foot in it a little and/or holding the starter on. You had it started several times, just the idle governor on these is a little slow even on diesel

[@TruckHoss]

Great video, thanks for sharing! Do you remember how cold it was out?

[@thequestionablecraftsman]

it was about 35-40 degrees

[@WymiataczPlays]

Hello there, could I use a fragment of your video for my American diesel trucky coldstarting compilation? Of course I will put a link to your original video in the description, increasing the original’s popularity too. Thanks a lot for you answer in advance :) 85% oil and 15% stale gas should be about perfect, never had my hands on a Ford IDI though here in Europe. Do you use any kind of fuel heater? Like taking an old auto gearbox cooler and fitting it so it warms up fuel via coolant? Obviously wont help on cold start but it sure does help later to spray and burn the fuel properly.

[@thequestionablecraftsman]

Yes that would be really cool! No i do not use a fuel heater. Its not very cold where I live though. It may be in the teens (farenheight) for a month out of the year

[@WymiataczPlays]

@@thequestionablecraftsman I recommend it anyways, winter or summer, won't do any harm and will only help! (Just don't run over 10-15% gasoline with it installed, too much gasoline + hot fuel = vapour locks in the fuel system) Brings the fuel to a lower viscosity taking stress off the fuel system, helps it pass through the filter, spray more easily and efficiently through the injectors, burn more efficiently and cleanly... And in scorching hot summer, it won't do harm either and it will definitely take away some warmth from the engine :D Example: watch?v=_FCf6WnALQA Best of luck running it eitherway, the 6.9 IDI shouldn't care much, but why not give it just that little bit more of life:)

[@pakwagenplays8990]

How is the 6.9IDI? I have been looking at older Ford diesels and came across one that I might be interested in

[@thequestionablecraftsman]

I like them. They're pretty much the same as the 7.3 idi with minor differences like the glow plug controller. They also don't have cavitation issues since the cylinder walls are thicker

[@Jefforey]

Hey man I got a 86 6.9idi 4x4 f250 supper cab. Buy the old ford diesel! you will not regret it! Easy to work on parts are very reasonable decent fuel milage and will tow anything I use it for on the farm! Just it's not a speed demond other than that love these old trucks

[@niklauswalther-schroeder2461]

I owned a 1984 f250 with the 6.9L and all I have to say is there reliable and slow as crap BUT can pull a house off its foundation Easy to work on very simple Parts wasn't too expensive either

[@northkoreabestkoreao9690]

[@Jefforey]

Got a 1986 f250 6.9idi c6 4x4. My question is i put a pump new injectors injector return line kit new high pressure injection lines fuel filter. No leaks anywhere yet in mornong cold sitting over night it takes alot to get it to fire off. New batteries cables and nippondenso starter 5 days old. I push the vavle next to the fuel filter housing hissing so i can see air is in the system. So im looking to fing the leak? Air intrusion is my issue any ideas where else to look?

[@jaybarringer6514]

I have a 6.9 i deleted the mechanical pump and put a sump in the tank with a electric pump and then converted to 7.3 glow plugs and controller and It starts right up no matter what temp but when the glow plugs where bad it wouldn't start when it was 70 out

[@thequestionablecraftsman]

I did what @jaybarringer6514 did as well. I have an electric pump and switched to 7.3 glow plugs and it always starts right up

[@Jefforey]

Thanks guys trying to keep the old truck alive. Also got a tapping noise under driver side vavle cover suspect a rocker? Found a 93 7.3 idi 200.00 complete whole truck. Fresh batteries and bled the system it fired up! Body is okay adverage so now have two. Lol how do you guys set and also adjust the timing(pump) for better fuel milage

[@olaflarsen9523]

what kind of batteries are those?

[@thequestionablecraftsman]

They're just cheap batteries from walmart

[@JuneohSevin]

Why would you even think to run used motor oil in an engine that is made to run diesel fuel only. I have several 6.9 diesels, I would never abuse them like that.

[@thequestionablecraftsman]

@@JuneohSevin research alternative fuels. It’s done all the time

[@VineV-Dutch]

​​​@@thequestionablecraftsman if you want alternative fuels: try a LPG engine. Used motor oil isn't an alternative fuel, sunflower oil, vegetable oil is. Don't know what you've been reading: but it sure wasn't good. It could l causes wear and tear on your motor, bearings, piston rings, exhaust system, valves and rubbers (fuel lines). It's also bad for your health and the health of others driving behind you. Not to mention your environment and flower garden. You're indeed a questionable man... However: definitely not crafted when it comes to reading internet in combination with using your commen sense and/or your brain Let me guess: your also so stupid to believe that Trump is there for the blue colored guy instead of the rich, and that Trump won the previous elections fear and that the elections were stolen? Instead of you believing the proven fact that he tried to influence the results, and he is a convicted criminal?! And the fact that it's proven he has had a big hand in the storming of the Capitol on 6th of January? Where working blue colored people (policeman) died??!!

@@VineV-Dutch what’re you on about LMAO I am not sure why you’re so angry but it’s not good to project that onto strangers.
