Default coolant leak

the title basically says it. I dida pi intake swap at the beginning of this summer and just last week it started leaking coolant bad, like i had to fill it up everyday(not an issue now as i have my winter car out). It seemed that it was leaking from the drivers side rear of the intake manifold. So i tore it apart today and it all looks fine, my gasket maker stuff was still in there and the intake gasket looked good as well. However there is some oil in my actual intake??? I assume that the rings are just worn out(104xxx miles). So i do not think that all of the coolant leaked out of the rear of the drivers side intake, you guys got any ideas?

I doubt your rings are bad at 100k. Maybe a head gasket leak.

When you took it off what part of the intake was wet. What did you use gasket maker on on the intake? There is nowhere you are suposed to put gasket maker on this engine except the timing cover.
