SO I TOOK THE CAR TO ( 2 LOCAL GARAGES )
THEY BOTH RAN THE ENGINE FOR A GOOD WHILE - BROUGHT UP TO HIGH TEMP' - THEN PRESSURE TESTED THE CAR.
THEN LEFT TO COOL DOWN -- HAD A VERY GOOD LOOK OVER THE CAR --- NO SIGNS OF LEAKS
WERE FOUND ANYWHERE FROM HOSES OR BLOCK OR HEAD GASKET OR WATER PUMP.

Hi james
I understand your concerns but we can only offer you so much information, as i have said previously any garage worth its salt should be able to diagnose the fault you have, if it can't you need to move onto someone who can, i,m a bit puzzled to be honest why a leak cannot be found as you have mentioned you have a leak under the car, you need to get the coolant system gas testedand pressure tested for head gasket issues and the block pressure tested for internal issues, its not rocket science, speak to your freinds and see who they can recommend.
good luck

Usually the water manifold going into the main block behind where the water pump is mounted ,this pipe work is secured in place by a set single set screw M6 ,the reason for using a set screw is because the seal at the block end is an 'o'ring pushed up against a shoulder on the pipework,however this sometimes gets split when refitted due to the bore having some sharp egdes ,the 'o' ring is squeezed into place by the offset of the M6 screw ,hence the need for a set screw,as the engine cools the pipework contracts and breaks the seal slightly,any defect in the 'o'ring then allows coolant to escape,which runs down the block to the underside ,most of the time it looks like your water pump has gone.
requires 1 'o'ring ,and a bit of fiddling
