RE: 1991 190e 2.6 nightmare!!!!
Let me address acouple of things here...
On the SL600, there is a water manifold on the back side of the engine, which is made of plastic and is notorious for cracking. There is a thread on here or *****************, discussing this very water manifold. Recommended replacement interval is 100,000 or when it cracks and starts leaking... One enterprising owner fabricated a new manifold out of metal to prevent repeat infraction. I do not know personally, but it is alledged to be a bastard to gain access to...
On the 190, I doubt a head gasket will leak like you are reporting... Sounds like something else for water to leave that fast. I suspect water pump, or piping somewhere to loose water that fast. On a cold engine, with engine off, if you add water, do you see it running out on the ground? Can you discern from where?
In general, "Stop-leak" products are only good where the leak is a seeping type of affair. Full blown leaks will overpower any stop leak products unless you put in so much as to "bridge the gap", so to speak. Using that much will also stop up thermostats, heater cores, etc so I would not advise it.
