I have a 1997 Fiat Ducato 1.9TD Campervan. It has a bad waterleak coming from what appears to be underneath the Inlet Maifold Housing. At the moment it won't hold any water, it runs out as fast as I can pour it in. My mechanic wants to find out what parts he needs before he takes it in and ia asking if anyone has had a similar problem or know where I can get an plan of the engine. He doesent have much space and can't really start work on the van until he has parts as he does not have space to hold on to the van for days while waiting to get parts. Any help would be great, thanks
