A turbo that fails shortly after a rebuild is frustrating, and unfortunately common.
In most cases, the failure isn’t because “rebuilt turbos are bad.”
It’s because the root cause of the original failure was never fixed.
Here’s what we see most often.
Common reasons rebuilt turbos fail again:
-
Oil feed or return lines not replaced or cleaned
-
Improper balancing of the rotating assembly
-
Incorrect bearing clearances
-
Reused damaged components
-
Installation errors during reassembly
A turbo rebuild done without full inspection and verification is a gamble.
Why balancing alone isn’t enough:
Balancing individual parts is not the same as balancing the complete rotating assembly.
Even small imbalances can:
-
Accelerate bearing wear
-
Cause vibration at high RPM
-
Shorten turbo life dramatically
Longevity comes from correct assembly and correct balance.
How MIC Turbo does it differently:
Our rebuild process focuses on:
-
Full disassembly and inspection
-
Identifying the original failure cause
-
Correct clearances and verified balance
-
Preventing repeat failures
Because fixing the symptom without fixing the cause doesn’t work.
What to do if your turbo failed again:
If a turbo failed after a rebuild, it needs to be inspected before any decisions are made. In many cases, the turbo itself can still be saved once the real issue is addressed.
