Second approach: 30.0 Nm.
Check after removal
Using a straightedge and a set of flat feeler gauges, check the deformation of the contact surface of the exhaust manifold. If the obtained value exceeds the norm, replace the exhaust manifold with a new one.
Post-installation check
Start the engine and run it at high speed to check for exhaust leaks.
