3116 water going directly to oil pan

When you drain the rad there will still be water in the block unless you pull the block drain plug behind the cooler under the turbo.
This is what the cooler looks like as its removed.
I cant see it being able to leak through the cooler and into the oil pan very fast.

Seen a few cam follower failures on 3176s and C13's, a holed block is the usual result. Never seen one on a 3116, but the design is similar.

If it steal runs build some ramps out of 2x6s .

To qualify? To qualify for what a free sh!ty plate of pancakes and sour a$$ coffee. I still qualify as a number three grease monkey. Besides those places are for people who drag there wardrobe
around behind them on wheels, those folks don't carry bags.

we have 4 of those things in the bunch. had one do just about the same thing as described in this thread about 3 yrs ago. push rods out the top water in the oil and crank broken in #2 hole . replaced with a used unit . I had the used eng uprated to 240 hp by cat its still running

Had one at 170 HP in a Cat 950F. Meter stopped turning at 27K hours long before I ever laid eyes on it. Cannot attest as to how many hours were on the engine but it never gave me any issues. It’s like these guys pulling 400 (or more) HP out of a 5.9 Cumapart.
It’ll do it but for who knows for how long.

Ok that makes sense. When draining. I have the issue when filling. I never did drain the radiator, it was empty on its own. Completely empty. I'm assuming from the leak. When I pour in coolant. at resorvoir, I can almost immediately hear water trickling in pan and the level rises on dipstick. My question is: If the leak is up higher at the head or camshaft galley, wouldn't the radiator level come up and stay at the level of the leak instead of leaking completely out below the level of the leak? That's what's throwing me off. A block and a radiator are basically 2 containers linked with a tube at the bottom. Even if you do have to pull a plug to drain the block wouldn't the radiator retain the same level as the block retains? That's what keeps making me thing the leak is below radiator level. The only possible asnwer is if it has to be running for the radiator to fill and thats why no water is going in the radiator? Doesn't seem too likely. Sorry to keep hammering on this but I learn a lot from you guys. Just a note- engine runs like a Singer sewing machine. Hate to just write it off with so few miles.

Most system fill bottom up Thru lower hose and would not empty radiator as much of the cooling system IE water jacket is above the half way point including oil cooler.
Not acquainted with orientation of or how internal radiator plumbing on your machine,
Some older low cab forwards even the old GMC square cabs radiator bottom(and cross flow)was above highest point of water jacket.

Well it does fill from bottom up and the water pump and oil cooler are pretty much in line with each other at the very bottom edge of the block. The bottom of the radiator is 2-3 inches above them. Seems as if the radiator drains out it would have to be related to their area. Everything else is above the bottom of radiator. When it dropped the 2 push rods and knocked the cam follower cover out, there was oil all over the highway. LOTS of oil. After I got it home and drained the oil [jet black pudding] , i got about 8 gallons out of a 5 gallon capacity pan. I'm sure thats where all my coolant went. Not to mention all that was on the highway.

If the oil cooler leaked that badly, your cooling system would have more oil than the oil pan. you need to pull the pan and see where the coolant is falling from. That's the only way to know for sure.

Agree
Oil has more pressure than water so would force feed the other way first
Radiator should have been a oily mess had the cooler failed first.
Pan needs to come off and validate where is flowing from.

I'll do that. I started on it the other day then it got nasty out and hasn't cleared up yet. I don't really want to bring it in and tie up the space so I'll wait for a break in the weather.

Removed oil pan. Block cracked at camshaft galley. On to the next project installing the 8.3. Gonna start a new thread on that. Thanks for all the input.
