INFINITI QX70 oil leak around turbocharger observed after mechanic inspection on INFINITI QX70

Some INFINITI QX70 owners report experiencing oil leaks around the turbocharger due to various issues. Common causes include oil system component failures and leaking engine gaskets. Additionally, a damaged turbocharger may lead to oil leaks, which can decrease performance and potentially cause engine damage, necessitating a turbocharger replacement. Exhaust leaks near the turbo can also contribute to oil leakage, disrupting the oil seal function and affecting turbo performance. Blocked or restricted air intake filters may result in oil leaks at the compressor end of the turbocharger. Furthermore, conditions such as piston ring blow-by and crankcase blow-by can increase crankcase pressure, impacting oil flow to the turbo and causing leaks at either the turbine or compressor ends. It is essential for owners to seek professional assistance to accurately diagnose and address these issues to ensure optimal turbocharger function and prevent further engine damage.
