Rounded Rocker Cover Bolts

[showbeastie]

Went to take off the rocker cover to clean and respray it, and replace gasket. Two of the bolts were badly rounded. Tried to hammer in a Torx bit, but no joy and was worried of causing further damage.
Any ideas on how to free them?

Dremel a slot into the head and use a chunky socket screwdriver bit. Well, that worked for me. Need replacements? I may have some I was donated knocking around that you can have...

Torx worked for me, gently tapped in a gently turned. Afterwards I could actually use the correct allen key :lol:

Remember, the three front bolts screw into the inlet manfold, so BE GENTLE!
over enthusiastic whacking can result in a holed manifold which gives a whole new set of problems..

I have successfully drilled off the top of the allen bolts and then removed the threaded shaft with molegrips.
