Well as the title says I have a pretty significant seepage up high on the engine in that area. We're thinking it has something to do with the gear tower or the intake manifold/valley pan. Anyone have any experience with leaks in this area. Valve covers look pretty dry, and I tend to suspect the head gaskets would leak coolant or mix coolant and oil rather than just weep oil to the outside. Any help is appreciated. We arrived at this diagnosis by pressure washing the front of the engine (being careful not to hit the IP or alternator) and after the engine was clean (er) we saw a significant seepage of oil in the area of the IP tower and thermostat housing. Not using or leaking a drop of coolant but my oil consumption has gone from not too bad to moderately severe in a short time.
