Check after treatment system for damage or clogs, blockages in after treatment & exhaust may lead to excessive back pressure which can lead to turbo seal damage & oil leaks.
Pressure test charge air cooler
Check CAC piping, hoses, & clamps for damage
Check turbo oil lines for damage, leaks, & blockage. Insufficient oil flow can lead to overheating & damage to turbo.
Check oil for contamination: Dirt, metal shavings, or other contaminants can cause excessive wear & damage to turbo internal components.
Inspect for excessive carbon build up: carbon deposits can break off & cause turbo damage.
Make any other engine repairs prior to turbo installation
Avoid hot shutdowns, frequently shutting the engine down while hot can cause turbo to overheat & damage bearings.
Excessive engine wear, high temps & speeds can lead to premature turbo failure, responsiveness issues, potential loss of power, or inability to regenerate
Before replacing turbo, it’s imperative to diagnose the underlying cause of the failure to ensure the issue is resolved & prevent future failures or problems.
