Are the any of threaded bolt holes, lower thermostst or right side coolant to block, open to crank case or
oil passage? As seen from below, I have
oil showing on the right coolant pump to block boss. I'm working with flashlight and mirrors. I don't see
oil in the famous corner of head-manifold-block, I do not see any oil trying to run around the pump boss as if it were from above.
Now I need to wait for everything to cool to remove any pressure from the coolant system. I'll try the bolts on the coolant pump, one at a time, looking for oil residue and then dope the bolt threads and reinstall If that isn't it, I don't know. Prieviously I was blaming the valve cover gaskets, used the neoprene with steel reinforcement gaskets what disappointment to find it's still leaking somewhere else.
