Every leak I have ever had on my FE, be it
oil, coolant, or cash, has "trailed back" so that it looks like it is coming from a place that it's really not. When your engine is cold, wrap some white, nice paper dinner napkins around your hose ends, the curved aluminum tube ends, the water pump to manifold hose, around your weep hole, around the fittings that go down in the intake manifold, and the heater hose ends. Then warm the engine up good in the garage or driveway so the coolant system pressurizes. Then remove and check the napkins. A leak that "seals itself" when your engine really warms up can be a PITA to find. I like nice, easy to find leaks that leave obvious puddles.
