water in oil

[coxbl]

Looking for some suggestions before I tear down the engine
I have an L4200 that the water flows directly from the radiator to the oil pan very quickly.
I assume there is a freeze plug or o ring that has failed.
I have removed the water pump, and it appears the problem is below the head.
The tractor was running fine but started running hot, so I cut it off and checked the water. The radiator was empty, but the oil pan was full of oil and coolant
Any suggestions

Pull the gear case and look at this plug:

Thanks for the info.
Any way to verify this without taking the gear cover off.
If not, does the governor and oil filter housing have to be removed

got a bore scope?
You could pull the speed control plate and look in there.

You don't need to mess with the governor or the filter housing.

Just pull the speed plate in Blue and remove 2 springs off the arm, then one spring off the pin in the gear case cover.
Pull the crank pulley and off it comes.

Question:
Is the pulley and nut 2 different pieces and is the nut RH or LH threads
Just checking before I mess something up
Thanks again for the info.

Normal threads on the nut and 2 pieces.

I have removed the nut
What is the trick to remove the pulley from the shaft
It has 2 holes in pulley - does it lock on the shaft or are these threaded to help pull it off
Thanks

It doesn't lock on, just a normal keyway slip fit.
Use any pulley puller to get it off.

Is there a way to remove the cover without pulling the motor

Don't pull the motor, just drop the front frame and the axle down.
There will be these bolts attaching the front frame to the side of the engine.
Support the engine from the bell housing and after removing the bolts you can lift the engine enough to get the cover off.

Just verifying
Can I drop the frame without pulling the front drive shaft off
Didn't want to break something else
Thanks for all your help

I would pull it, as it's easier when there is one less than binding it up.
It's really quick to pull the propeller shaft cover and shaft.

Just pull the bolts out of the cover, slide the front cover back, drive out the roll pin on the front coupling.
You don't need pull the cover and shaft out of the back it can just hang. or you can then pull and drop the cover and shaft out of the way.
