A lubricant passage is formed within the turbocharger housing and configured to supply oil from the at least one oil gallery to the turbocharger cartridge assembly to lubricate the at least one bearing. A seal assembly is disposed at least partially within the turbocharger housing to receive lubricant from the lubricant passage and includes a sealing end configured to seal against the turbocharger cartridge assembly.
