thanks Guys. I had to fit about 15 new studs, and its only on two of these that I am getting a weep. What I need to do is a compression test at some stage just to make sure that I dont have a head gasket problem, but I am sure I dont. Am trying to work out where the water will be coming from. I guess it must be through the thread at the bottom of the stud and all the way up, as long as the head gasket is holding the only place for it to get out is through the top. Having started with two leaking water pumps I now only have one, but it just wont stop. I have bought a couple of NOS pumps but am reluctant to fit it as I am hoping the dripper will stop soon. Its just a bit of a bore as I havent filled it with anti-freeze yet in case I have to drain it down to do the pump and lose all the solution. Sadly my engine does not have the correct taps in the block for draining only plugs so the water will go all over the centre engine bay unless one of you has a cunning plan. I feel the need for some more on track testing
