valve cover bolt broken......holes on air intake hose...

Hey fellow Aveo owners....

New to the Forum....

I just wanted to know if any of you all know the specs of the bolts that go on the valve cover. I recently changed my valve cover gasket but got over excited and accidentally broke one of the bolts when putting the cover back on. It doesn't look like it's leaking any oil from the broken bolt, but i just want to change it before anything bad really happens.

Also, can holes on air intake hose coming from the air filter to throttle body cause my TPS to go bad, or is it just saying is bad because of the extra air going in? I ordered a new hose but now wondering if I should also by a new throttle body because i guess the TPS can't be bought by itself.
