Why Does the Turbo Fail and How to Repair It?

Model: (Various brands) Various
Part: Turbocharger

Video tutorial

In this video, see what can cause turbo failure: the first is a foreign object (due to an ineffective filter) that can break everything at high speed; lack of or insufficient lubrication (it operates with engine oil); however, the most common cause is blockage in the exhaust system (catalytic converters, DPF) that severely strains the turbo, overheating and wearing it out; moreover, under these conditions, the turbo consumes a lot of oil on its own. Repair requires new parts and careful calibration on the bench before the piece can be reinstalled on the vehicle.

In any case, all this work can be avoided with proper maintenance: keep the air filter in good condition; constantly monitor engine oil levels; and ensure the exhaust system is always clean.
