Hi Dan,

How about that. I'm trying to find an almost identical leak on the passenger side of my 90 245. I had this engine out last summer so everything is clean and new and I've been keeping a close eye on it.

No oil as yet, but my coolant reservoir is down about 1/2" after a year and half and 6K miles. The only evidence is a drop or two every night, coming off the bracket that holds the tranny coolant lines, but I'll be damned if I can find where it's coming from.

Have you checked the drain plug on the block ? Something crawling back along the steel pipe from the water pump ? You're in Florida, so it's unlikely, but I have seen pinhole leaks on that steel pipe adjacent to the weld on the clip, directly under the manifold outlet.

The heater core is a suspect, but I had my dash out for blower replacement a month ago and inspected it. On a previous failed core, there was evidence on the inside of the windshield when defrosting and leakage on the floor.

I would just like to know whether or not my leak is coming from my new head gasket. Does anyone know if there's such a thing as water soluble fluorescent dye that could be added to the coolant ?

regards, Peter
