I have puddles of oil on top of my Intake in a new to me 1967 coupe. The car has been neglected but over all in great shape. Anyway I took the 4 bolts out that go into the oil gallery.
I’m assuming this is the cause. Just looking for some verification. Valve cover gaskets seem to be good.
If the valve covers have been over tightened they leak ,it dimples the bolt holes and alows oil to keep between the cover and the gasket . To fix remove the valve cover ,pound the bolt hole flat again then replace the gaskets with the rubber fell pro gaskets
Are you certain it’s oil? Lots of time, a slow fuel leak from the carb tends to pool in those same points on the intake. I would do what @horse sence says to do first. If that doesn’t eliminate the puddle of fluid, try tightening the four screws that hold the ends of the carb together. Good luck.
I've seen fuel leaks collect dirt and look like oil sitting in the recesses of the intake, so most likely it is fuel or valve cover leaks as pointed out above.
I had exactly the same thing happen, fuel on the intake which I thought was oil at first. When I first got my current '67, it had a wrong year Autolite 2100 (a red herring in this context). This carburetor was leaking at the accelerator pump and the fuel pool looked like an oil pool.
I now have a correct year & size Autolite 2100 carburetor that I rebuilt last year. I am in the process of getting it dialed in, etc. This Summer I had a bit of flooding due to heat soak, which I am taking care of. It flooded and I could see a bit of fuel "seeping" from the throttle shaft, not enough to cause a leak and pool on the intake this time, but something I'm going to be on the lookout.
Sorry for the long winded way of me saying " yes, I had a fuel leak that pooled on the intake that I thought was an oil leak at first."
