Blazers have a 4.3L vortec engine. Also have a rearwheel drivetrain, most have 4x4 too. hell yeah my blazer can tow a Uhaul. could probably pull 2. (think the towing limit is like 4,000-4,500 pounds.)
The stated towing capacity of the 2000 Chevrolet S 10 Blazer is 1500 pounds. There were options available that could raise the towing capacity to 3500 pounds.
If it is a vortec engine, it is probably the lower intake manifold gasket. In most cases you can smell it when the engine is hot.

On the 4.3 vortec: to check for a leaking system, Remove plastic vortec cover, Then remove the round black thingy on the top and look in with a flashlight. It SHOULD be dry. If it is wet, you got a leak. Could be fuel pressure regulator (passenger side) or fuel line (driver side).

10243880 if from 95-00 Vortec. Closest I could find.
Could be the driveshaft.
Any electronic 4.3 can be fitted into a second generation Blazer. You could even swap in a V8 - I've seen 5.3, 5.7, and 6.0 swaps done - if you so wished, although it wouldn't be a simple "plug and play" application. The 96 - 02 Blazers used the L35 variant of the 4.3 Vortec engine.

It might not work as well, but possibly, it could work.
