Coolant in the valley!

So i have been chasing a Coolant leak, I suspected the water pump, or hoses, worst case i was afraid of it being the oil cooler. Yesterday i washed the engine and let it sit. Today I put on the pressure tester and watched it drip down under the front of the engine on the drivers side. As i traced the leak upwards i found it was coming around the HPOP cover and there was coolant in the valley.

A couple things i know
- There is no coolant in the oil
- It is a slow leak under normal operations
- The engine does not have 25K miles on a re-build, a bad plug of some sort? freeze or otherwise
- This truck has never been a daily driver, and gets occasional use for hunting and fishing and such
- The rig is a 94.5 with the manual tranny

So my question, has anyone had similar issues? Is it possible that the i have a leak in the timing cover? Any help would be great

I've never really heard of coolant in the valley before. How much coolant is in the valley? Did you check heater core hoses?

There are freeze plugs on the front and back of the heads, but i don't see any way that coolant could get into the valley from them. Only thing i could see is a hose leaking, or a cracked block/head, or maybe a blown HG.

I could look down the seam where the heads and block meet. No fluid or wet block. I just saw that there is a puddle in the valley. Not very deep, just that there is some green fluid.

I checked the hose from the pump to the heater, but now that I think of it I did not check the other one. I wonder if the fan could have blown a little bit of coolant backwards and it pooled in the valley?

My next step is to flush out the valley and blow it dry with air, then start dry and pump it up again.

I thought it was coming from the area under the drivers side of the HPOP in the front. Is there a passage between from the water pump through the front timing cover?

Green fluid in the valley could be diesel. Coolant would have a hard time finding its way up there.

A painful update. Started finding a small amount of snot under the valve covers and then it showed up on the dipstick. Coolant in the oil. Not much but it was there. Took it to a good mechanic cause I don't have time working 7-12's. Timing cover gasket.

He also pressure checked the coolant system while looking and under the valve covers. He pulled the fuel filter and it was clean. Compression was good, no oil in the radiator.

It was showing up as a light drip over the starter. And would drip under the power steering pump. I hope the cover isn't cracked

Sucks for your find but for a ray of light this will give you the opportunity to install a 96-97 front cover and then you can run a SD HPOP.
