not really the greatest suggestion considering its like a 17/19mm bolt.....

also not forgetting steel pieces arent the best thing to have floating around inside your sump.

if its just done up too tight....un do it?

if its stripped then smash a small socket on it (something imperial will be slightly smaller than the metric) and un do it that way.

becareful dont hit it tooo hard or you'll just bend the sump, its only thin metal.
