Mystery coolant leak below intake plenum

[cvtvm]

I've been tracking a very very slow coolant loss over the last few weeks, I decided to take a look around the engine to find anything that could be seeping and ended up spotting this under the intake plenum. Does anyone have any idea as to where this leak would be coming from? I would like to order parts in the next few days to have this addressed and installed.

Lower intake gasket would be my guess from the photo: https://www.google.com/search?q=sit...9AiSAQQyMi4xmAEAoAEBwAEB&sclient=gws-wiz-serp

But it could also be coolant seeping from the throttle body/IAC hoses so check there first.

One time it was the gasket the other time the coolant hose. Had both between three 4Runners.
