No as soon as i fill the reservoir it empties in twenty minutes

There is a good chance that there may be a rusted out freeze plug leaking in behind the manifold where you can't see so well. That would explain the dripping and quick loss of coolant.

Coolant leaking from passenger side of engine

Yes there would be a welsh plug in that area and it is probably rusted out.

1992 chev s10 , 2.8 v6 , leaking freeze plug

If the welsh plug is in a position where by removing several items ( manifold --engine mount etc and you can get enough space to swing a hammer to install the new plug. then it can be done with difficulty. If the plug faces the fire wall then unfortunately the motor has to be pulled . The only advantage is that it is just not the one plug because if one is rusted out the rest will not be far behind so it is an opportunity to do the lot.. IT is a good reason to always ensure that the coolant conditioner is always changed regularly and kept up to percentage required.

Coolant loss, approx one litre every 200kms no visible leaks,doent fault under presures test's

could be that you have a leaky welsh plug have a look under the car where the transmission meets the engine and see if you can see white residue there is a welsh plug behind the flywheel which seems to give trouble on falcons also there are 5 behind the exhaust manifold which are hard to detect if they are leaking have had this problem with mine only has 80 000 on clock

Coolent leaking

i doubt very much wether the block is cracked it is more likely to either be a heater hose may be leaking or a welsh plugs ( little round dish shaped plug ) in the side of the block i would first check all the heater hoses and the look on the side of the motor for a possible welsh plug leak i'd say its hoses tho
