Pull the oil dipstick out, if the oil is creamy white, then that is a good indication of a blown head gasket or a cracked head. The creamy white oil is a result of water mixing with the oil, and in the case of a blown head gasket. Coolant from the coolant system. Often seeing creamy white oil around the oil filler port is just from condensation.
The heads are the "caps" that go over the tops of the cylinders. On your engine, the 3.0, has two heads and six cylinders. Each head is bolted down over the tops of three cylinders.
From your view standing in front of the engine compartment, one head will be in the back covering three cylinders, and one head will be in the front covering three cylinders. You can easily trace to where they are by following the spark plug wires to where they plug into the spark plug.
All six spark plugs, three in front and three in back, are bolted right into the heads, and if you unplug the wire and remove one of the spark plugs you can shine a flashlight right through the spark plug hole built into the head and into the cylinder. The good news is that they're so easy to find.
The bad news is that the heads take some doing to remove. You would need to remove EVERYTHING from the top of the engine to reach the heads. Fuel system, ignition system and emission components. As well as such things as the intake manifold, alternator, timing chains, etc. It's not difficult, just time consuming. That's why it costs so much to take to the shop.
I'm sorry this is so lengthy and detailed (I just read through it myself ? ). I hope this helps. I would imagine the repeated stalling could be caused by a cracked head or a blown head gasket, however before you put too much work into replacing those components, take some time to perform as many tests beforehand to make sure. I would even recommend getting a mechanic to look at the car since we are not able to. If it's something simpler to fix, you'll want to know about it before you tear the engine apart.
