I have a 36kw liquid cooled quiet source, SN 6180486  36KW 2.4 120/240 1P NG ALUM  running on propane.
I recently installed the cold weather circulating heater kit. Ran the generator for a bit to check for leaks and found none. Everything seemed ok.
I plumbed it from the supplied T fitting with the coolant temp sensor on the top and the hose on the bottom. Routed the hose under the pan to the other side and fastened the heater to the frame rail. Installed the new fitting in the block in place of the drain plug at the back of the block near the generator. Everything looked good and no leaks.
Minus 18 C today so I went and plugged in the heater for 1/2 hour. I could hear it working. Started the engine and immediately had oil and antifreeze gushing out the dipstick tube. Top hose in first pic connects to top of rad. Hose at bottom of brass T goes to heater on other side of engine. Second pic shows where the other heater hose connects to block

I think the block port must be an oil galley - water pump is pumping coolant into the oil system and filling the oil pan.

That's what I though initially too but when I took the plug out for installation I got nothing but antifreeze. The  original plug has a smaller drain plug in the center. I'll check the installation instructions again. I guess I could also revert to the original plumbing, drain and change the oil and antifreeze and see what happens.

Well then, it looks like you got the right port. Did it always have antifreeze in it, did you have to add water - just wondering if it froze in a pocket and cracked.

When you removed the plug on the side of the block did antifreeze run out?

If you had a cracked block I don't think it would have gushed out.  I would guess you may have the wrong port and have forced water/antifreeze into the oil system.

Yup. I had drained the radiator already and this just let the rest out of the block, I assume.

I honestly can't see any other port on that side of the motor that looks like a candidate.

Always antifreeze, good to minus forty. Anything less than that here in Saskatchewan and you are asking for trouble.

Tomorrow I guess I'll remove the tee on the intake manifold side and re-install the plug on the exhaust side. Change the oil and see what I find

I agree, go back to the stock configuration and see what happens.

So confused... Went back to original configuration and everything works just fine. No puking out the dipstick tube, the oil stays clear, not milky. No pressure out the dipstick tube or out the oil filler cap and no bubbles in the rad.
Clearly I plumbed the coolant system into the oil system, right? But when I loosened the temp sending fitting, I got a coolant drip, just like I should. I also loosened the plug on the exhaust side that I had removed to plumb in the heater and I got............antifreeze, not oil. Not even a drop of oil.
I guess I'm thankful that the stupid thing runs again but WTH?

If it ain't broke don't fix it! Makes you think you just having a bad dream.

Does this unit have a turbo blower on it??

It does.

The turbo should be fed with oil only to the bearing, and a drain tube out of the bottom back to the oil pan.

I'm not sure what you're getting at. I didn't mess with any of the fittings or oil lines to the turbo when hooking up the heater. The plug I removed and then subsequently replaced is located at the back of the engine.

I wish it was not 0 degrees F, I'd ask you to figure it out and let us know since you have the machine to examine and we don't.  And I'm curious because I believe both of those ports go into the water jacket.  Is that where the instructions said to put them?
State your problem, not your diagnosis.

The plug I removed and then replaced was definitely into the water jacket. The instructions are a little vague as to exactly where the fitting goes on that side. " Drain coolant from engine block by removing existing plug from the right side of the engine block." The diagram sucks but shows the plug to the left of the dipstick tube near the rear of the block.
I think I plumbed it in correctly but can't for the life of me think of any related reason it would have done that. If it was just a coincidence and the head gasket had blown at the same time, then wouldn't I have had the same problem once I went back to the original plumbing? It seems to run just fine now.

I think that plumbing set up should have worked fine.  

Apparently the only thing that could have happened is when you replenished the coolant you lost you poured it in the oil fill hole on the valve cover rather than the radiator fill on top of the generator.

Nope.
The oil fill  requires a complicated setup of elevated funnels and hoses because of the enclosure.
The radiator fill is the only readily available access on the out side of the enclosure.
It's winter here now and minus 30 C outside so this may have to wait until springtime. I'll use the mag pan heater for the winter and see what happens.
