through for a starting issue on a FORD Powerstroke Diesel engine.
~Truck Won't Start?
~Truck Takes a Long Time to Start?
~Crank No Start?
~Hard/No Start When Hot?
~Hard/No Start When Cold?
The engine used as example in the video is a 6.0L, but the same principals
and techniques apply to the 7.3L and even the 6.4L and 6.7L.

7.3L Changing the HPOP Oil - Sludge?
Some people insist on changing the HPOP oil in the 7.3L because if you
dont, you will never get that oil out and it will become sludge...... or so

FORD 6.0L Diesel ~HPO Leaks~ Oil Rail -to- Fuel Injector Nipple Cup Seals
If you are getting High Pressure oil leaks at the top of your injectors,
you probably have leaking ball/nipple cup O-rings. If you just replace your
top injector O-rings, you will end up with leaks at these seals again.
~~~ UPDATE at 20,000mi~~~~ Follow-up Video:
I have some better stronger O-Rings available still, if you don't need the
See my Complete Write-Up on this problem and solution over at the FTE
What happens is the O-Ring that seals the nipple cup to the oil rail fails
and you get a high pressure low volume leak that travels along the nipple
cup body down to the top injector seal and eats away at it. Leaks at the
ball cup seal can generally not be detected with a standard shop air
pressure test of the HPO system. You need to test with a Oxygen or Nitrogen
bottle to get up closer to 1000PSI to actually hear/find leaks at the ball
Don't make the mistake of just replacing the top injector O-Ring and not
addressing the real problem above it!

injector O-Ring seal.
Ford 7.3 Powerstroke fuel tank mods. Harpoon and Hutch
I had a truck that needed work done to his pick up and he asked about doing
the "hutch" mod and harpoon mod. So I made a video showing the mods and
also included the way we did it years ago without reinstalling the pick up.
Parts needed. 3/8 5/16 unions. 1 foot 3/8 2 feet 5/16 line.
7.3 Powerstroke Hard Start Up and White Smoke Diagnostics
We had a customer bring in a 97 7.3 Powerstroke turbo Diesel saying it was really hard to start
and smoked a lot of white smoke when it did finally start. This video will
show some common causes of hard cold start and ways to diagnose the
problem. Upon removing valve covers and listening to it run we determined
the injectors O-rings weren't sealing properly, so we made this video to
show you how to do an o-ring replacement for your injectors and how to
remove and install the injectors. If you have any questions or comments
