I recently noticed having to add coolant too frequently, could smell coolant after driving a while(heavy smell), but see no evidence of a leak on my garage floor, the GM mech. Said it was a bad lower intake gasket, im fine with his diagnostics, but he estimated $820 for the repair! Is there something cheaper I can do, at least temporarily, to slow or stop the leak, short of buying coolant every couple of weeks?

When these gaskets go bad, there are a few different scenarios. You may end up needing an engine if you don't replace that gasket. I wouldn't drive it until then.
