I wasn't sure. Always good to look in the oil filler to be sure.

Good luck finding someone willing to weld a cast iron cylinder head. The best option for this condition is to install a TUPY 0331 head casting. Search on https://www.car-part.com/ for a 2002-2006 TJ, LJ or WJ cylinder head. I'm sure there are several in your area. Have it resurfaced, have a valve job done, and replace the springs/seals. New gaskets and head bolts, you're golden.

But get that oil analysis done asap.
