On most vehicles, yes.
Yes, you need to replace your intake gaskets.
Because it 's leaking- OIL, ANTIFREEZE, or vacume leak
The leak would vary on the size of the hole or seal failure.
If it is leaking from a bad head gasket, it is because of a bad head gasket. If it is leaking from a bad intake manifold gasket, it is because of a bad intake manifold gasket.
Either a heater hose or a leak at the intake manifold
The manifold itself could be cracked. I have a 2000 Pathfinder LE with 100k miles and a 3.3. I noticed an antifreeze leak on the right side of the top of the engine. Using a mirror, I found that under the manifold, there was a nice crack.
It's probably leaking from a bad intake manifold gasket. You could be leaking from the heater hose that comes out of the firewall very close to the manifold. They sometimes leak there and drip down on the manifold. If it drips on a coil, it can eventually ruin the coil. It happened to me.
Upper intake manifold plenum leak/crack most likely. If its blowing out coolant then you probably have a bad head gasket.
Yes. Antifreeze is actually pumped through the intake manifold. If the gasket is bad it is possible that it leaks out
A leak of antifreeze and water from the freeze plugs or from a radiator hose could cause you to find the fluids behind the intake manifold and firewall on your 1995 Toyota Runner. You could begin by checking the hoses to see if all hoses are sealed and clamps are tight.
It is common for the intake manifold gasket to leak antifreeze from the corners of the intake. Need to replace intake gasket. Be sure to look closely at the intake were the gasket seals against it for pitts in the intake. There is a heater hose that goes into the intake on right rear corner in the back, but uo on top of intake. check closely.

ya, especially if you are leaking antifreeze internally or externally. if intake manifold gasket leaks usually have vacuum problem result in "rough engine idle" look for external antifreeze leak at manifold gasket first. then check oil for "milky color" - if antifreeze runs low due to leak = Yes - engine overheat. Dont drive it - you can do a lot more damage if you do.
