CAT(Mitsubishi) P7000- S4S Diesel

We have a Mitsubishi S4S Diesel. Back Main Crank seal is leaking. The seal has been replaced at 1800HRS and 4400Hrs. Have found nothing wrong with oil pressure and crank shaft wear. Has anyone had any problems with this engine????? Used OEM CAT parts every time. Any thought/ideas would be appreciated. Looking for a 4th and 5th opinion.

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
