Help needed Ford 4000 1967 engine problem

Here is some background about the Ford 4000
Year: 1967
Fuel: gas
Number of cylinder: 3

About two weeks ago I replaced the water
pump & lines because a leak occured at the
bearing/gasket. While I had everything
taken parts I degreased & power washed the
outside of the engine. Wow the amount of
junk on this engine. Buttoned everything
back up and my work seemed good until some
smoke was occuring on the left side of the
engine. My original guess was a couple of
drops of oil were hitting the exhaust pipe.
After bush hogging 5 acres the engine
started to smoke more. It was also +90F
outside. After I finished I check the
coolant and it seemed full. Fast Forwards
to today and I needed to bush hog 1/2 acre.
From the start the engines smoked a lot. I
only made 1 lap and stopped the tractor. An
hour later I check the radiator and it was
completely empty. So I filled it back up
with 50/50 and did two more lap. I noticed
the tractor was loosing power, smoking even
more and a metal sound from the engine.
Thinking it could be a big problem I parked
the tractor and made a quick video to show
you'll. What do you think is wrong with my
tractor?

Welcome to the forum.

Of course you know your video didn't post??? I believe that's at least partly due to the fact that you are a first time poster here.

My guess - and that's all it is - just a guess from what you've shared. Your engine has ingested enough coolant to tear itself up. Coolant in any other part of an engine than the cooling system, very rapidly damages engine components; especially in the copious amounts it sounds as though you put through yours.

Where was all this smoke coming from? First you said it was coming from the left side of the engine and you thought a couple of drops of oil got on the exhaust pipe. Then later you said there was a lot more smoke. If you pull the engine dip stick to check the oil level, what do you see?

As you know, no coolant may have caused significant damage. You might want to start analyzing what's wrong by removing your oil filter and cutting it open. You can do it with a die grinder by cutting 1/4" below the base of the filter. Just cut through the outer wall of the filter. Inside is a pleated paper element. You can look in the pleats or remove a large section of the paper element and stretch it out. If it's full of metal, you know you have a problem, at which point you would want to know if the metal was metalic or non-metalic. Non-metalic would be bearing material. Metalic, something worse. This is pretty easy to do and would tell you whether you need to remove your oil pan next.

Was wondering where it was smoking myself.
The crank case vent tube dumps on the left side on gas engines.

Here is the video:

The smoke appears to be coming from the upper left side of the engine. Near the exhaust manifold. Due to the fan it is very hard to pin point the origin. My original guess was oil was hitting the exhaust pipe, now I'm thinking it is coolant vapors. See video I just uploaded.

Video was just added, this might help
you'll.

Ok let me do this and I'll report back.
Please see video I just added. Also I
checked the dip stick, no coolant in the
oil.

Ok I just uploaded the video. Please take a
look. My ears might be oversensitive but
the engine does not sound right after this
problem started. Do you think I could have
a blown head gasket? I check the oil and it
looks good, no coolant in it.

Sorry! Video doesn't work for me. Dunno if it works for anyone else or not.

Here is the link again. I doubled check
with some other people and the link works
😁

Thanks again for the help

Ok I cut open the oil filter and it has
metallic pieces in it 🙁 does this mean it
is a complete rebuild?

I have a 1969 gas engine from a 3500 that ran until they took the distributor out to rebuild it and never put it back in. I took the loader off to use on another tractor. I will sell the engine for 500. Just an option for you. Located in Clinton, TN

That looks like bearing material. Run a magnet through it to see if any of it is iron. Next, do a compression test. Post the results from the compression test. You'll need to pull the pan and inspect the crank. The head will likely have to come off but it's too early to tell whether your cylinder walls are out of spec or not. If you get lucky and your crank is not scored, maybe you will get by with a head gasket and bearings, but that's a lot to wish for. Maybe I misinterpreted your video, but it sounded to me like you were running that engine at high rpm. Best to run it at low rpm when you have engine damage.
