Oil in the Intake Manifold!?

Well I was going to replace that vaccum servo I took everything off any found this.



Any clues on whats causing this ? There seems to be oil inside the throttle intakes too. :surrender:

There is DTB for oil leak from oil galley plug. See arrow. Looks like leak has been stopped. What you see may be residual. Looking at buildup around intake ports you may have oil leak from valve covers.

Before disassembly clean area with compressed air. Don't let junk fall into cylinders.
