Cracked engine head while torquing oil pressure sensor

Overtightening or stressing the threads while replacing an oil pressure sensor can crack the engine cylinder head, causing persistent oil leaks. While some drivers resort to temporary fixes like epoxy to seal the area, a cracked head ultimately threatens the structural integrity of the engine block and requires a permanent repair or replacement.

I changed the sensor and when I torqued the new one to specs, it was still leaking so I took it out and noticed the crack in the head.source ↗
