So its me again, I am looking for a way to change the engine cover bolts. The top left one is completely snapped, the bottom right one has no thread left and the other two are somewhat ok. It really bothers me that they look horrendous but depends on the amount of work needed to change them for new bolts, if it is too much work or requires specialized tools, I might just leave it without the cover

So any help how to replace the bolts?
