will a damaged manifold do any damage as there appers to be a hole in mine on the right side beside the nut/???tnx 

If it is the intake manifold you are refering to then yes that is a serios problem. Air leaks can burn up your top end.
how the hell did that happen? thats your flange, is that a stock exhaust? i would fill that in if i were you.
i tink its ment to be like that cause its the same on the other side! i filled it with high temp sealnt nyway lol
