@DieselDC, you clearly have a better understanding of these engines than I do, anything other than a RMS that could cause such a dramatic oil loss in such a short period of time, and only when running or adding oil to the crankcase with the engine off?

You give me too much credit lol. Okay what is rms?

Clue me into this oil lost situation so I can picture what’s going on to see if I can help.

IT'S ALIVE!

Sorta...

Got my electrical stuff sorted out. Turns out that if you ground the glow plug relay instead of going to the starter relay in a fit of ineptitude, bad things happen. Also got the RH battery cable properly grounded. That fixed that. Unfortunately, that means that the fuel pump was able to run, and allow one of the feed lines to do a pretty decent Old Faithful impression. Had to get new seals for that. $30 for some little bits of rubber is offensive, but it fixed that.

Tonight it was time to crank it. Took 30 seconds or so of cranking, spread out over two or three attempts, but it fired up and ran. Smoked like crazy from somewhere around the turbo, so I'm guessing that I didn't get the up pipe clamp on right. Didn't have any coolant in it so I shut it down pretty much immediately after it found idle.

And noticed a torrential oil flow from the flywheel inspection cover. Like, multiple streams. Stopped almost immediately after the truck was shut down. It didn't occur to me to check the rear main while the engine was out, but plenty of regrets now. Hoping it's something like a line that's not connected right, but given the remarkable quantity of oil that it lost in 5 seconds of running, I don't have high hopes.

And the drama continues.
MAYBE A PLUG AT THE REAR OF THE HEAD.....OR A LOOSE OIL LINE IF THERE IS ONE TOWARDS THE REAR OF THE MOTOR?....

Yep, rear main seal. I noticed that it dripped a little bit when filling the crankcase for the first time, but it stopped pretty much immediately after pouring. Starting the truck up, it runs multiple steady streams of oil out of the flywheel inspection plate. Since it leaked when the truck wasn't running, the only thing I can think of is the rear main.

@GETFURIOUS thanks!

If it’s not the main seal, like above, it could be the

rear galley plugs (1/2” Rachet square head to remove) and riffraff sells the o-ring or plugs plus o-ring

Rear cover. To reseal, this must come off with the rms :(
Hpop line leaking (engine is tiled back and will run back to towards the rear)

Cracked cylinder wall (really, anywhere)

Those are the only things I can think behind there.

Well that narrows it down a good bit. Since it leaked as I was adding oil and before I ever tried starting the truck, combined with the sheer volume (imagine if you turned a full quart of oil 90 degrees onto it's side) I think I can safely eliminate the hpop, cracked cylinder, and rear cover. First two since it leaks when stopped, and second by sheer volume. No way the rear cover leaked like that unless it had a gaping hole. Guess I'll hose it all down with brake clean and try to figure out where it's leaking from tomorrow.

This is a pain.
