Crankcase guard

Hello again with a new problem :) As my friends went with my 206hdi the other day, & nbsp; the vehicle officially sat on the asphalt. The vehicle was full and heavy; but the asphalt road, perhaps tire tracks, might have been pitted a little. However, as we had no apparent unevenness, we went through the asphalt as we were leaving without the need for slowing down. I stood and looked in a flat place; The plate, which I think is the enclosure, stands at a slight angle from front to back. so it gets closer to the ground as it goes towards the middle of the car. Is this his normal stance or could he be displaced? Would it be possible to take this higher?

The back of the CARD is metal with a 2 nut screw. If it yawned, it may have slipped down. It can play in the jolts and make a noise.
