What should I do if the engine foot fixing screw hole slips and the screw can't be tightened?

1: directly enlarge the bottom hole and replace it with a larger screw! Of course, the above vias will be enlarged like this!

2. Lower the wire sleeve to solve the problem. The method is the same as the oil bottom screw slipping. Car repair is expensive, and the general price is around 100 yuan.

Recommend the second method!
