Engine oil leak 2019 DSDP

I brought in my 2019 DSDP 4018 (mileage about 6000) in for it's first annual service and they found an engine oil leak. The technician described the repair he did below and he completed the annual service. I was notified that my coach was ready for pickup. I arrived and noticed a puddle of oil. It was still leaking. I left and called for progress about 4 hours later and they said it had been taken apart and put back together again and was still leaking. I was told they will investigate further and see what needs to be done. Has anyone else run into this kind of leak? It is only a year old with low mileage. I keep it indoors and the storage company said no oil on the ground. Any suggestions? Most of the language in the repair below is beyond my comprehension.


REPAIR DONE

RUN ENGINE WITH DYE AND FOUND OIL LEAKING FROM LOWER LEFT OF FRONT GEAR COVER AND FRONT CRANK SEAL RETAINER. THIS COACH HAS 2 FUEL FILTERS MOUNTED IN THE WAY OF ACCESS FOR FRONT GEAR COVER AND A FAN DRIVE MOUNT FOR FAN CLUTCH THAT IS IN THE WAY. REMOVE FUEL FILTER MOUNTING BOLTS AND SECURE FILTERS OUT OF THE WAY. REMOVE FAN DRIVE BELT AND REMOVE FAN DRIVE MOUNTING BRACKET. REMOVE SERPENTINE BELT AND THEN REMOVE FRONT CRANK SEAL RETAINER. REMOVE FRONT CRANK SEAL FROM RETAINER AND CLEAN FOR RE-REUSE. REMOVE FRONT GEAR COVER AND CLEAN SEALING SURFACES. THE CRANK SNOUT HAS SOME WEAR AND NEEDS A WEAR SLEEVE. CLEAN SEALANT OFF OF BOLTS AND APPLY SEALANT TO BOLT HOLES AND FRONT GEAR COVER AS OUTLINED IN QSOL. INSTALL FRONT GEAR COVER AND TORQUE TO SPEC. AND IN SEQUENCE OUTLINED IN QSOL. INSTALL NEW WEAR SLEEVE AND THEN INSTALL FRONT CRANK SEAL INTO RETAINER. INSTALL FRONT CRANK SEAL RETAINER AND TORQUE TO SPEC AND IN SEQUENCE. INSTALL HARMONIC BALANCER AND PULLEY AND TORQUE TO SPEC., INSTALL FAN HUB AND TORQUE TO SPEC. INSTALL ENGINE SERPENTINE BELT. INSTALL BRACKET FOR RADIATOR FAN GEAR BOX PULLEY AND INSTALL BELT.

Cummins would have to explain to me why the crankshaft snout would require a wear sleeve after 6000 miles.Sounds to me like either a defective front cover,bad harmonic balancer or an engine balance problem.In any case, I would involve a Cummins Rep.

Iam really surprised with only 6,000 miles they would not have contacted Cummins to handle this repair. Your still under warranty right! Usually on a warranty repair if Cummins is authorizing they want prior approval. Was this a
Newmar dealer handling repairs?
