Chitowndad,
That's a pretty high resolution picture you got there, I think could see a microbe crawling on your O2 sensor
.
Lil Bastard made a good point, check to see if the oil is migrating from somewhere like the oil filter housing. The air is so turbulent when driving it could come from anywhere. If it's not running down the side of the block you should be in good shape, just use some carburetor cleaner and clean the bottom of the engine and see what happens. I see you have CPC all over the place so it will be hard to disseminate between CPC and oil. I'm sure people leave the CPC on for certain areas of the country for corrosion protection but here in OK we don't have salt problems. The OEM obviously only sprayed in on to make the trip across the pond from the fatherland.
