Time to pull it.....
You are about to learn how to do head gaskets, minimally....If they are stock style gaskets you now have a bunch of graphite in the engine too. Check the bearings while its out, if you are using the stock oil cooler you will need to flush that as well. Turbo ate some of that oil too. If you have a stock timing chain you might as well replace that while you are there.....Welcome to the club.
