Seems like a PCV issue.few oil drop and I found that is coming form the throttle body
I'm very confident you have had, and maybe still have a PCV system failure. And yes, your intercooler is almost certainly crammed with oil.I am not sure if that new oil or still oil that stay in the system
IMHO, clean out the intercooler and install a PCV fix kit. The intake manifold valve has probably failed, but the nipple stayed in place. When you install the kit, ensure the turbo check valve and valve cover diaphragm are still good.
