Unless it's condensation at start up, the only way it could get there and still run relatively good would be thru the egr cooler. If your oil cooler is plugged, the coolant flow to reduce the egr temps can't work properly.
As a result, your egr will super heat, then crack, and allow the limited amount of coolant running thru it, to go back into the intake as the exhaust gases would normally go.
Not a good thing as you can hydrolock your engine before long, once that crack opens further.
I would be very careful about running the engine until you have it checked out. If you monitor eot and ect, you would probably see a 20 plus degree difference when driving.
The only other way would be to have a warped head or blown head gasket. If Either of those were the case, your engine would really run rough.
