hi

i have a slow cascade of oil leaking somewhere under the intake manifold between cylinders 2 and 3. there are a couple sensors there tapped into the block i think a knock sensor and a coolant sensor ... any chance this could be the source of it ? or is it likely a weak spot in the head gasket that is leaking up from wind etc and coating the highest of these two sensors ? it of course also leaks down and after i wipe it, fresh oil is there anew all the way to the oil pan. can someone suggest places to test or look? ... i'm trying to dry the engine bay of oil before switching to synthetic.

front 3 seals are done and valve cover gasket done, everything front and top and exhaust side is tight and dry, just need to deal with the firewall backside and this drivers side now.
