Inspect oil lines for blockages, leaks, or contamination before installing the new core. Ensure the oil supply line is clear and the return line is not restricted to prevent bearing damage.

Monitor for unusual noises, oil leaks, or excessive smoke during the initial start. Record idle speed and boost pressure if available to establish a baseline for the new core.

Confirm that the intake and exhaust manifolds are free of debris, carbon buildup, or foreign objects. Cleaning these paths helps ensure stable operation of the new turbocharger core.
