hey MudBros... back again for some help. this truck will be the death of me

(recap) rebuilt engine 2500 miles ago on a 250k 92. ran killer ect. noticed i was getting a little 'milk' buildup under valve cover oil cap :crybaby: started to panic a little hoping it was just condensation.... wiped out, pulled dip stick and oil looked good, but a little more milk at the top of stick... coolant level was ok. next fill up again same checks, more milk and coolant reservoir was low filled up and really started sweating.

so now im wondering after pulling into my shop and yarding the head if i my have made a premature decision. i noticed there was a large amount of moisture in the upper and lower intake manifold which i thought was weird. and the head gasket appeared to be fine and the pistons had alot of carbon for being so new... so my question is, why is the intake manifold so wet? and the truck seemed to have some high idle issues which could not be resolved with the idle adj screw, its all the way in and still seems high, and the cold start is very high, at least compared to my 82 with a weber.... if anyone has any input id be glad to hear it....
 
I believe coolant runs through the intake manifold though a passageway. Maybe its cracked?

double check this though, I could very well be full of BS.
The thermostat housing is part of the upper intake.
I don't quite remember how those passageways are routed.

you might be able to use dye and acetone to check for cracks.
 
There is coolant that runs through the throttle body, it keeps it from icing at the venturi. Maybe it's leaking there somehow?

The thermostat is located on the lower 1/2 of the intake so I doubt that could be the problem but at this point ill take and suggestions I can get. I tried plugging one end on the coolant line and blowing in the other and it seems to be air tight. My head has been milled once at least and its height is 3.754. So I'm still wondering if the head wasn't 'tight' if coolant could have been blown back up the intake? I dunno sounds far fetched has anyone else seen this? Sorry about the bad pics.
