My engine dust cover has partially fallen, can I still drive on it?
The dust cover under my engine has fallen down on one side and slightly drags. No one close by me fixes this type of thing (not even sears) so I’m waiting for my husband to come back from a work trip to fix it next week. Can I still drive on it?
yes you can, this is just for protection of water n all, but not that important i havent had mines ever since i bough the car, and never had a problem, and my car is lowered to the ground. as long as you do not doa ny offroad you should be fine
