The lower intake manifold gasket will be the problem. This is a high failure rate item and GM has redesigned the gasket a couple times in an attempt to correct it. Currenty Napa has the best replacement gasket and it is known as a "Perma-Dry".
I have done many and have never seen a warped intake. It's worth the fix, take your time and torque the gasket as per the instructions provided.
Good luck

Intake Manifold gasket replacement and/or leaking= Ford

Intake Manifold gasket~

Replacing intake manifold gasket:
Replacing the intake manifold gasket, I used the tube kind, it's a make it youself for about $6 (it's blue and the consistancy of toothpaste) follow directions carefully! You can get a tube at Autozone or any car parts store. Has been working great. Just ask the cashier for the make it yourself kind of intake manifold gasket. Sorry, I don't remember the name of it, it's been that long...lol...

As for the Intake Manifold leaking coolant....It could, but shouldn't. One of the largest problems I've seen for coolant to leak out the Intake Manifold has been due to pressure in the system somewhere... Check the classic area:
Water pump- look for either water seapage and/or coolant. You'll know if it is because you will see real water either coming out of the water pump leak hole or under the thermostat. Most of the time coolant will pool where your heater hose runs in the intake manifold.

Mentioning heater hose. Check for leaks, holes, and/or cracked heater hoses. In-addition to the water pump, heater hoses...Check the transmission system, exhaust system, fuel system, radiator system, A/C system, secondary fan (located above the water pump housing), and thermostat.Also, check all electrical connections....Hummm....This is almost the entire workings of the vehicle.

NOTE: "It seems to be an infinity kinda thing... Once one thing starts to fail and is ignored, you are bound to be fixing a chain of event failures. Therefore, Do not ignore even the smallest problem or you'll be bound for life in repairs...."

Water leaking underneath the motor

A little leakage is normal. Also the A/C will drip water, but that comes down from the firewall area.

From the motor, it may indicate a leaky water pump. This will drip from the front of the engine which is the right side as the driver looks. The pump is located under the timing belt cover.

Also check all your large hoses to see if a leak has developed at any joint.

The V6 engine often develops a water leak under the intake manifold which is hard to see. The water appears on top of the transmission. Camrys will often also get a split in the plastic radiator top tank, so look there.

If you are not losing large amounts of water, you have a while to track it down at leisure !

Water in the oil. hoping it's coming from the back plate of the water pump housing.

You either have a blown/leaking head gasket or a bad intake gasket. Don't drive the car in this condition, you will hydrolock the motor. Get it towed to a shop when you can or you will be paying for a lot more than just a head gasket/intake gasket.

intake manifold gasket. when it leaks water will enter a cylinder causing the sprark plug to short out. when the engine gets hot enough the water will cook off in the cylinder allowing spark to take place. 80% chance intake manifold gasket, buy the upgraded part. 20% chance head gasket. Take the intake off and check for broken intake manifold gasket then buy parts.

Loosing antifreeze but no leaks

The loss of antifreeze with no apparent leaks could be the sign of many things including blown head gasket, cracked tank, or leaking water pump. I would lean toward a head gasket first. Have you checked the oil for signs of antifreeze? A head gasket won't leak until the system is under pressure and running at normal temperature. You could also have a cracked head although that is pretty rare. Check the oil and plugs for signs of anti freeze. Also check the tanks on the side of the radiator they could be cracked which only leak while under pressure. Check all hose connections and if so equipped tranny cooler lines to make sure they are all attached correctly.

There is a water port there. So it is possible. If you try cleaning the area as good as possible and then start the truck and let it run and watch that area. More then likely it is the intake gasket.
