I have an 09 fx35 with 160000 miles. Was going in to replace spark plugs and found the oil was milky under the oil cap. Coolant level was also low and has had to be topped off twice. Signs are pointing to a blow head gasket. Upon tearing down the upper intake, we found there was white smoke wisping out of the plenum. The valves also had some green wet tint to them like there was coolant on them. I do believe I have head issues, but what is with the coolant on the valves and the smoke from the plenum? Plenum also smells of fuel and there is a slight misfire upon accelerating and low rpm driving. Any help would be greatly appreciated!

I should also ask, at the cost of my sanity, is it possible that an intake manifold gasket can leak coolant into crankcase? That is the only explanation for the green tint on the valves. And it's a wet green not a burnt valve green!
