The engine blew a head gasket and when it was running I pulled the oil fill cap off to look for water in the oil and the engine ran like **** and died. Started it up again and pulled the cap off again and it ran like **** again until i put the oil cap back on...WTF causes that?

It's a blow-by problem. Massive amounts of positive crank case pressure, that creates a weird vacuum leak type symptom (when oil cap is removed while running). That engine is garbage. scrap it and go with a 22re or a 4.3 vortec. You'll be very happy in the long run. But I am sure you have heard all this before
**** small block chevies.
that's all I have to say about that.
I'd rather have a 3.0.
And 3.0's blow combustion gasses into the cooling system when the head gasket goes.
Not even close to the same thing as bad rings and excessive crank case pressures.
Unless the coolant takes out the rings/cylinder walls, then it'll have excessive crank case pressure.
That usually takes a while though.

The crankcase is supposed to nearly nuetral pressure at idle, it has a fresh air (atmosphere) inlet and and PCV valve.
OPening a big hole in the crankcase (oil filler) creates a new/different inlet than the one in the intake tube, screws up the flow that the rest of the thing was designed around.
3.4 maybe. No pushrods. :awesomework:
(yes I hate chevy, sorry)

This is correct.
It's designed that way. The 22R/22RE and 3.0 and probably quite a few other engines all do this. They also splatter oil everywhere when you take the cap off.
A lot of people misdiagnose this as "Blow-by" which it is NOT.
As far as your headgaskets go. The 4Runner is worth a LOT less than the truck for whatever reason. I think you would have a hard time selling it at 1200.00 but You can get the gaskets done for about 900.00 out the door assuming everything ran fine before they blew. At that point the rig is worth more than 2000.00 probably more like 3500.00
The rig is worth what some dumbass(?) is willing to pay. Anything 3.0 aint worth crap.

Very true, They sell for 1,000 to 1,200 all the time for fairly clean ones.
People try and get 1,500 + all the time but I usually see them on Cl for months.
I agree kinda. the 3.0 has it's problems for sure. But what engine doesn't? The 22R also has problems. It's just way way easier to pull and much cheeper to fix.
That pic you have there shows some serious neglect. That doesn't happen like " I was sitting at the stop light in my well taken care of 3.0 and boom"
No that story usually is preceded by "I pulled RIGHT over"
IF you had the money I'd say find someone who can slap a set of HG's in and then sell it running cuz it's worth more to you that way.

And you still don't even understand what was explained above. Was it because he spelled things correctly and used punctuation?
So far, you're the only one with bunched-up panties. Your credibility is diminished when you advocate "people just give there opinion and not run around telling people there wrong" but you keep responding to other peoples' posts, implying that you're right and they're wrong.
You can't have it both ways son.

First of all, everything you write makes my eyes bleed. Second, who said anything about an engine swap in this thread?

If you don't ming getting shitty fuel economy along with not enough power and possibly working on it alot, it's GREAT.
I bet the one I'm building right now goes well over 200k with no major issues :corn:
