It is cold here, so I am unsure if it is the smoke because of the antifreeze. Would it be more white or darker? I've not seen anything dripping from the pipe either.
I checked the overflow tank it does not seemed to be cracked.
Could the Blazer be burning that much antifreeze if a sensor is off, or if the water pump is not working right?
You side it could be filling the crankcase; that would be the part of the engine with piston which gives the car its power from, right? And if that is the case, it sounds like an expensive job?

I hate to be the bearer of bad news, but if you are going through that much antifreeze and not finding a leak, it is going to be expensive. If it is not leaking, it is probably being burned in the engine. That could mean intake manifold gasket, head gasket, that sort of thing. Not a job you would want to tackle yourself as it is a big job even for an experienced do it yourselfer.

I yesterday I put in more antifreeze, and then discorved a leak. I took it to Autozone to get a read on my check engine light to see if that was part of the ordeal. After the scan two codes came up, P0101 and P0420. The print out that was given to me listed several things for each number.
When I asked the guy to give more details on the items that it had said, it did not seem like he knew what he was talking about.
Here is some of the things that were listed,
1.Vacuum hose off
2.Throttle body intake tube loose, cracked or off
3.BARO (Barometer)/ MAP Manifold Absolute Pressure defective
4.VAF (Vane Air Flow) MAF (Mass Air Flow) sensor dirty or defective.
1. Catalytic Converter defective Do to possiably to 2, 3, or 4.
2. Engine misfire or running condition
3. Large Vacuum leak
4. Engine oil leakage into exhust-valve guide seals piston rings.
The guy at Autozone said I should try and do the vacuum leak first cause it showed up on both of them. Now, to me,he did not know what he was talking about, so i want to make sure before undertaking this ordeal it is handled the right way the first time.
If any of those could be linked to the leakeage of antifreeze and the heat not working, could you let me know. : ) Thanks car guys.

Where did you find the antifreeze leak? If you found it up on the intake manifold area, you probably have a blown intake gasket which would cause all sorts of problems such as what the code reader found.
Intake manifold gasket failure is somewhat common on high mileage 4.3L engines.
