What damage does a blown turbo do to engine?

A blown turbo can cause significant damage to an engine by allowing excessive oil and boost pressure to enter the combustion chamber, leading to oil contamination and potential engine knocking. This can result in severe wear on engine components, such as pistons and cylinder walls, and may even cause catastrophic failure if debris from the turbo circulates through the engine. Additionally, loss of power and performance can occur as the turbo fails to provide the necessary boost. Prompt diagnosis and repair are essential to prevent further damage.
