High pressure oil pumps are not common causes of failure on the 6.0L Diesel. There is a branch tube that when separated causes excessive cranking times due to low oil pressure to high pressure system issues. This doesn't sound like your problem. I would recommend a second opinion - try to find someone who has serious experience with these challenging - yet very fixable engines.
