i would just buy the complete top end gasket set from Toyota and button it back up if you are positive it's the head gaskets. But, if you are going that far you might as well buy a timing belt, tensioner and water pump too. Just my 2 cents as I had to deal with blown head gaskets on my 95 3.0 4Runner a few years back.

New development
When I got home this afternoon I noticed coolant on the ground under my 4runner. I took a look underneath and it looks like it's coming from a canister looking thing bolted to the block??? drip drip, does anyone know what this is?

well you said that it's leaking from there externally right? are you sure your head gaskets aren't leaking and dripping down onto the oil cooler?

Honestley no, they may be. Would they leek when cold like that? I was hoping it was this thing, prolly easier to fix that head gaskets. Just wasnt sure if it was possible to leak coolant into the system from this thing.

Me....no.
But I did see a thread yesterday about what a radiator looked like when dissected, and some talk about a "strawberry milkshake" that occurs with transmission fluid mixing with coolant. Does an oil cooler operate with coolant?....I know, stupid question, but I don't know how that works since I don't have one......if it doesn't, I can't understand how that cooler could be a suspect.

It would be my assumption that it's leaking through the head. Could be leaking into an exhaust port somewhere. As it warms up and builds pressure it will leak into the exhaust. When you turn it off the coolant may be low enough that it does not push into the exhaust this could be why you don't get any at cold start-up.

I am gonna assume here that this smoke cloud is coming out of the exhaust/tail pipe, correct? It wasn't mentioned where you were seeing the cloud from.
If it is coming out of the tail pipe, then you are burning it, if you are burning it, then it is getting into the combustion chamber/s. It's not leaking into the exhaust, it is leaking into the cylinder/s and burning and then being exhausted, but not leaking into the exhaust.
It's not dripping down and hitting the hot oil cooler, and the oil cooler is not leaking coolant into your oil, as you mentioned you have no milkshake. Even if the oil cooler was leaking coolant into your oil, you wouldn't see any burning coolant/white smoke, as your engine doesn't run on/burn oil, at least not enough to make a cloud of white smoke out of the tail pipe.
You are seeing this could of smoke, you say it smells like coolant, you are losing coolant, and it has overheated, and it's and older 3VZE.....I'd have to say 99.5% it's a HG. Sorry.

I'm thinking it's a leaking HG and when it leaks it goes into the exhaust side maybe leaking on an exhaust valve. I don't think it would be the oil cooler, if so you'd have a milkshake in the crank and you don't correct?
My 22re HG went (I know this is a 3.0) it was on the exhaust side and it started with the same symptoms but steadily got worse. Never had the oil shake either.

Lumpy, do you mean leaking at the HG and going straight into an open exhaust valve?
I guess that's a possiibility, but with the cloud he is describing, I'd say it's burning it and then exhausting it.

i was re-reading this thread to see if i missed anything.
i saw that you said you flushed the radiator and got stuff out of it.
um...replace the radiator. do yourself a favor and eliminate that as a future culprit.
ok, back to our mystery.................................

given all the symptoms described and the 3VZE's reputation like I said before and others have stated the odds are stacked against you that it's the head gaskets...

Here is the plan...
Change the HG and give the up-most best writeup on it so I have the best of the best to follow.
May as well do the timing belt, water pump, maybe oil pump, thermostat, don't forget new head bolts.
Here I am writing my shopping list in your thread.
