The coolant I add to my coolant tank empties out in less than 5 minutes. The only leak that I can actually see is coming out of the connection point at the heater hose (not to the engine but leading into the cabin I think). I can hear boiling coolant when I listen real close and I can't find any other leaks. I am not sure if there would be any other concerns other than replacing the hose itself.
If you do not fix the leak you can damaged your engine, water pump, which will mess up our engine. If you have a leak and can fix it, do it to help yourself. It may be that you have other leaks but fix what you can see and check for other leaks. Change the hose and hose clamp, it is a cheep fix to keep your vehicle on the road.

when you say left side are we talking passanger side or drivers side if drivers side which is my guess most likely your waterpump seal is leaking

You may very well have an internal leak as in a blown head gasket. If you see white smoke from the exhaust and it smells sweet that is a definate sign you do. You may also notice a white foam on the underside of the oil cap and the oil level may be over full. Remove the radiator cap, engine cold, and start the engine. If you see air bubbles escaping you have a blown head gasket or cracked head. Stop driving the car until you verify this with a compression test. Severe engine damage will occur if you continue to drive this car, if the head gasket is blown.

remove radiator cap on resevoir and remove hose on the side hold hose over bottle have someone start the car hold rpm at 3000 if coolant isnr rushing out of the hose the water pump is bad if coolant flows the temp sensor is bad

WOW! that's pretty darn hefty no matter who ya are. Are you loosing very much oil? If not at least get the heater hose replaced(but not from these guys) And while its at a independent shop, have them look at that turbo oil leak-yes should be repaired, turbos don't like to run without oil, but could be just a loose line. Check with friends, family, and neighbors to see who they recommend to work on your car. I don't know were you live, but I would bet that there is a foreign car specialist around.

There is, however, an air outlet into the driver's foot area. If the heater core is leaking, the air coming through the heater core will carry the droplets into the entire air ducting system. The driver's foot area may be the closest outlet. If it smells like coolant, you need to replace the heater core regardless of where in the cabin the coolant is coming out.
It appears that you have a minor leak at where a hose attaches to an engine or radiator pipe. When the engine is hot any leak will evaporate quickly and therefore not be seen. As the coolant heats up it will expand into the overflow tank but once the engine is stopped the extra heat build up will force the coolant out the leaking joint. As the engine cools, the leak prevents the coolant from being sucked back from the overflow tank.
The heater hoses and those pesky little bypass hoses in the cooling system tend to go hard and split if they are over 10 years old. Check all hoses and clamps for a good tight fit and replace any hoses that have gone hard or have become soft and stretched. Those spring type hose clamps tend to be less effective in clamping as the hoses age. Worm drive ones are the best to use.
If unsure take vehicle to a cooling system specialist and have them do a pressure test and more thorough diagnosis.
If problem persists, then it could indicate a problem with the head gasket (Usually caused by allowing engine to become excessively overheated when cooling system has run dry) allowing very hot high pressure combustion gases into the engine water jacket, which super heats the coolant in the engine block, which then boils off, and is released via the cap or any leaks. If the head gasket is really bad it will leak water into the cylinders and into the oil in the sump. This is indicated by an emulsion of water and oil mix on the dipstick. You will also see white smoke (water vapour) from the exhaust.
