Hey I’ve got an OBS 7.3 too. I learned how to correctly cold start it a month ago by doing some research. So I had thought that you’ve gotta cycle the glow plugs but you don’t. When the wait to start light goes off the glow plugs are still on. They’re on for 2 minutes overall even after it’s started they’re srill on to help it warm up. So what you do is you count to 30 or 40 seconds after the light goes off and she’ll fire right up. Worked with mine when it was 5° not plugged in. Let me know if it works!
Is there a reason you don't measure the amount of oil in the high pressure resevoir and then pour an equal amount of the new oil into it through the hole?
my fuel filter is turning black after only short amounts of time and i have a really bad oil burning problem. Thinking my injector seals are leaking and/or i need to replace injector cups? 290k miles.
The 7.3 takes 15 quarts of oil, not 16, so one quart less than a a full four gallons. This includes the pre-filled oil in the new filter. Important to know your specs.
Put fresh oil on the fuel filter gasket every time you change the fuel filter.Diesel fuel is not a lubricant and can make the gasket bind and be hard to remove.
That high pressure oil is fed by the normal oil pump to keep its resivoir full. Only thing you're doing by not emptying it, is mixing a quart of old oil with 4 gallons of new...
I enjoyed your video and wish you would've shown the oil filter removal--it's at a slight angle and I always spill some oil when removing it and was wondering if you have any tricks to prevent oil spilling when turning off the old filter. I've got a 1997 F350 7.3 and I never knew about the high pressure oil removal and I've put close to 100,000 miles on my truck without ever changing it. It's been running with a "hiccup" at times at highway speeds for the last 10K miles and I'm hoping in changing the high pressure oil that issue will cease. Thanks for the great videos you produce!!
Mike Snyder I know this is old, but simply pop a hole in the bottom of the oil filter and drain it as well into the pan, a good tip that can be used on any vertical mounted oil filter.

that makes sense because i notice mine did that and I thought the timer went out, thanks for the info bud
Thanks dad
It made my 97 ford f350 start up easy
As long as the GP's are good.
Some call it a crescent wrench, some call it a universal spanner, I call it a universal nut rounder.
You should fill the high pressure oil area with new oil and you won't have a hard time starting it to fill it up.
That's what I would do too.
The good old garbage can workbench.
What was the HPOP drain plug size? Thanks for the video and showing how to get that oil out!
Did you refill the HPOP or just let it refill itself?
I would replace the glow plug relay before trying to replace the glow plugs.
What did you do to get 19 miles per gallon
I like the straight pipe

Did that end up being the issue?
@@AlexGray idk the truck got totaled. I have a 6.9 idi now and i like it more lol
@@psd28what do you like more about it over the 7.3?
@@AlexGray cheaper and easier
@@psd28I’ll have to look into those, I’ve always liked the way they sound

Red Bluesome thank you, 13 in the crank case and 2 in the filter.
Is it still 15 if I’m not draining the hpop reservoir

Interesting point. I used diesel fuel. Are you suggesting that it will be hard to get the fuel filter loose next time I change it?
Add oil back into the high pressure reservoir ...
CAN you
Great question! That’s why it’s not starting up right away😉🤔
also you dont need to change the HPOP oil, just a waste of time. the LPOP is what feeds the HPOP.
I haven't ever changed the high pressure oil in my 96 f 250. It's not due for another 2500 miles. Can I change that oil now?
That high pressure oil is fed by the normal oil pump to keep its resivoir full. Only thing you're doing by not emptying it, is mixing a quart of old oil with 4 gallons of new...
What is the red toggle switch for?
Do you know where I could get mirrors like that ?
How do you get all 4 gallons I to that oil drain pan lmao
we just use 0w-40 in the winter and 15w-40 in the summer for everything, even
the lawn mower
the hell you putting diesel oil in the lawn mower for?
Lube the O ring on the fuel filter with diesel... just like the oil filter.
I changed the filter and it still turns on the light on the dash
You need new glow plugs and Relay and it fix that problem. My 96 it been 18 degree and she fire right up.
How much was that?
is the 1995 7.3 the same engine as the 96?
Yes, since 1994.5
Good video. Thanks
Just fill the hpop reservoir and it will start right up.
Right on good job Thank
NAPA is the Best!

I have yet to get that part down, This time i ended up with some in my mouth (dident have as good a hold on it as i thought).

@@Cortana2889 I will try this on my next oil change.
donaldson oil filter is the only thing i run on my 7.3
No need to change the oil in the oil pump it will get the new oil.
. Jfc man learn to use a glow plug relay right ....these things start in way colder conditions without being plugged in
don't need all the information on cost and all could be a short nice video

Looks like you need glow plugs.
Ad oil back into hpop
LOL...that's not expensive. I used to run Schaffer's Supreme 9000 in my 6.4. Now I do Rotella T4/white bottle.
Ever be interested in parting with her?
nope, think I have all the bugs worked out
