Common forms of damage to MG Roewe Maxus Engine include stud breakage and yield deformation. Stud breakage or elongation will cause the connecting rod big end to be unable to tightly bend the crankshaft, thereby weakening the restriction on the piston.

In this way, when the piston rises to the top dead center and starts to reverse, the piston may hit the valve or cylinder head that has not been fully closed under the action of inertia.

Bare Engine failures are more likely to occur on repaired vehicles. When maintenance personnel do not install according to the specified torque.

Over-tightening will cause stud elongation, and severely damaged bolts will break under the load and impact of Bare Engine operation.
