Hi, I have this really easy question. I have to undo those 6 bolts from crankshaft pulley(C20XE). Mine are not allen type, but some "almost rounded type". What key is used for them? How does it look?
Also, could you tell me what are my chances to undo them the usual way.They dont look bad, but are rusty a bit. If they don't come off, what then?
