I had a similar situation a few years ago. I was the heater hose leaking Preston which was somewhat diluted. It too was sweet...it's poisonous, so stop tasting it. Here's how you can check a difficult leak. Take the cap off the radiator while it's running, if the leak speeds up then it's a water leak from one of your water lines to the heater which is located near the firewall. Leaks do travel. Good luck and hopefully this solves your problem, I remember how it baffled me.

SOURCE: oil leak
this could be many possibilities. The best way to find out is to raise it up (if not high enough already) and wipe down everything that has oil on it. Once you do this you can sit there for a bit or do something else for a few minutes and come back to it. Use a flashlight to see where the oil may be dripping from and if you can not find it you may have to run the truck for a bit to see.

It could be as simple as a leaking hose, but it may also be a corroded alloy hose fitting nipple.
Get is seen to by a mechanic before it fails completely, causing complete loss of coolant and expensive cooked motor.

If the engine is the same as the 2002 Impala 3.8L engine, the problem is most likely cracked connectors where the coolant enters the engine block. There are two L-shaped plastic connectors that connect the coolant lines through the metal block attached to the tensioner arm to the engine block. Common problem and parts are available from the dealer for under $20, but takes several hours of disassembling and specific torque specs. Just replaced mine over the summer.

You likely will not like my answer but what you need to do is get underneath and actually look very carefully for the source of the leak. There is no place where both coolant and oil can leak at the same time. If you find oil in the radiator or coolant in the engine oil, then you have a bad head gasket. Usually though you would have an overheating problem or steam from the tailpipe and the engine would run poorly if that was the case.
There are numerous points where coolant or oil can leak. The list is too long to write. I'd definitely look at the hoses, radiator and water pump first though as they are the most common places coolant leaks develop. As for the oil leak, check the filter, valve cover and drain plug first, otherwise any place two engine parts are bolted together it's possible to have seepage from a gasket.
If you cannot find the source, any good shop can do a pressure test or dye test to find it for you.
