Or, if you want to try something that will not hurt anything, put in the large bottle of Q-Seal and follow the directions. My head gasket ('96 7.4L Gas) was leaking bad and thought I would need to replace it or rebuild engine. That was 26K miles ago. I put a new bottle of Q-Seal in with each coolant change (about every 12K). No leaks, no issues, truck runs perfectly.
