Someone used too much sealant on the cam covers. This blocks a critical "drain" in the cam cover/ cylinder head and elevates the oil pressure inside the camshafts. The cams are hollow and "oil" the journals. When the waste oil from the camshafts can't be expelled in high enough volumes, the pressure inside the cam increases and this is what forces the expansion plug from the camshaft.
Contrary to popular belief, this engine isn't like everything else's. These complications prove that and my ability to forecast the cam covers being resealed in the recent past proves just how much we see this, and how the constants are always there over and over again.
The person who sealed those cam covers should hear about this, or he'll keep doing this in the future.
