Thank you,,, will look at it. Also, Its only dripping when cold cold. Obviously heat is expanding something to make it stop or greatly slow. Could a head gasket leak coolant like that? I suspect either intake or EGR cooler hose or cooler.

The oil cooler cover to EGR cooler or egr bypass leak will show up where you describe too.

Another vote for heater valve. The heater valve on my truck only leaked when temps dropped really low.

Turned out it was the little 3" egr cooler coolant hose. Got a half turn on one end of the clamp and no more drippy...

Thanks to all who took the time comment
