(1) Is the air filter damp and does it have soil attached; Is there any water mark on the air filter housing and intake pipe wall.

(2) Check the oil of the Bare Engine and determine if the Bare Engine cylinder has water ingress. After water enters the Bare Engine, the oil around the cylinder head and intake/exhaust valve seats will appear milky white, which is the result of the mixture of water and oil.

(3) Whether MG Roewe Maxus Engine are flooded can be confirmed by checking the piston and connecting rod. Water entering the cylinder of an Bare Engine can cause it to break, and the top of the broken connecting rod piston will be very bright (the top of the piston is relatively not broken).

And the broken connecting rod is bent. In addition, we can also judge by observing the high problem of piston ring movement (top dead center) on each cylinder liner. It can be found that the top dead center of the cylinder corresponding to the broken connecting rod is significantly lower than that of other cylinders, which can also help us determine whether the connecting rod was bent before it broke.
