welcome to the site.
check out your CDR valve. that is the #1 culprit for oiling up the intake system. Not to mention that part is cheap too compared to a bad turbo seal.

Oil getting into your "intake" via turbo seal, or any other leak, is the #1 cause of "runaway". You "DON'T" want your diesel to "runaway"

Unless you have a big box to sweep it into, afterwards.
