1991 Ford Taurus White Smoke and Stalling
Black
White
Bluish
If its black, then your fuel system might be out of trim. If it's bluish, then you're probably burning oil. If there's nice clouds of white smoke, then you might have blown a head gasket. From what you wrote, the latter seems the most probable. Let us know for sure the smoke color though.
Thanks!

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.
The oil looks o.k. Just a little brownish in color. I only put 2 gal. of antifreeze in after changing water pump so maybe the stalling is because there isn't enough antifreeze however I'm not getting my hopes up (chuckle). And I know 2 gal. of antifreeze certainly isn't enough if it's burning out the exhaust.
thanks,

Suggested Repair
Confirm the smoke color and source. For white exhaust smoke with possible coolant in the oil, check compression, spark plugs, oil for a milky appearance, and the cooling system for exhaust gases before removing the heads. A dirty idle air control valve caused the stalling and should be cleaned; verify any head-gasket sealer is engine-safe and have a mechanic inspect it before major teardown.
Conversation Summary
A 1991 Ford Taurus with a 3.0L engine smoked badly, was low on oil, and later produced white exhaust smoke after a new alternator, water pump, and belts were installed. The expert suspected a blown head gasket or cracked head and recommended compression, oil, cooling-system, and spark-plug checks before teardown. The owner also reported stalling, no heat, and a fan that would not run, then used sealer. Cleaning a very dirty idle air control valve stopped the stalling and the car ran well, although the smoke had not yet been rechecked.
