Coolant Leak - Running Out of Ideas

Nothing external to the oil cooler. I'm not seeing any indication of coolant in the oil.

I added the UV dye and ran the car for a while. I pulled off the under-panels and looked at the water pump area, radiators, and the coolant fittings. Still no luck on finding where the coolant is going. The oil doesn't appear to be glowing. But I'm not sure if there was coolant in it, it would be enough to show up.

I'm still noticing the sweet smell when I start the car hot. So it's going in to the mechanic on Tuesday.

use your nose....really...try and catch a wiff ..is it the hvac ducts...coming in the window...front/rear of car..inside /outside...some cars have their heater fan motors running at very low speed even when the system is off so the smell could be coming from the vents via the heater core area

As noted, the heater core is completely dry.

You could have a slight leak in the head that is going directly into the combustion chamber and being burnt off. Possible head gasket, but more likely a cracked head...........

I think you're probably right. I hope it's just the gasket.

head gasket does make sense actually. That'd be a good reason why you're not seeing the glow.

No findy the leaky. All cylinders scoped after holding pressure on the tank for 12 hours and still nothing. It didn't drop this time either. I'll have to keep an eye on it and address it if it gets worse.
