Saturated 4.0 intake manifold

[Ibreakeverything]

I have alot of moisture on my intake manifold top and bottom at the back and at my exhaust manifold where it bolts to the engine. The exhaust smokes from the headers to the y-section of the exhaust for a few minutes at first start of the engine. Seems to be using more gas than usual and a slight rough idle. I just finished replacing the valve cover gasket. After searching forums and internet I think it might be a exhaust manifold gasket but the moisture is what puzzles me. Doesn't seem to be using coolant. Thanks

Did you verify that replaced valve cover gasket stopped the leak?
My manifold was just as wet on the bottom from oil, and that oil was dripping on 02 sensor which consequently was making it malfunction.

Replacement of the valve cover gasket did stop a leak at the valve cover, this current condition was noticed shortly after I replaced the valve cover gasket. Thanks for responding.

You figure out what it was? I have to replace my VCG as well.

was valve cover properly torqued to spec?
