Hi Nig,
Thanks for the reply, didn't know there was an Italian seal?.
OK, I have a cunning plan, well, not that cunning, and probably clutching at straws.
I watched a You Tube video (often a mistake), about tensioning the belt, in it it said the manual was incomplete, and the belt should be tensioned when the inlet cam was ramping, so the top run was tensioned between the cam wheels, the belt was pretty slack in that position, and should be tensioned at that spot. I did it that wayNow, I'm wondering if the belt was too tight, whether it could be flexing the water pump shaft or housing, and allowing a tiny bit of water to leak?.
I'm going to build it up again, tension the belt as normal, IE what the manual says, and leave the cam belt cover off, get it up to temperature and see if I can see any leaks. Yes I know, unlikely, but nothing to lose.
OH yes, another question, who is Zak Pike?, a fictional character?, it seems Zaks real name isn't Pike?, I only ask because my surname is Pike.
Alan.
