This question already has an answer here:
My dad and I were trying to take off the manifold on our Nissan and the bolts will not budge. We don't have the money to do it and we need it done because we don't have any other car. We tried spraying it, my dad broke a tool and I got cut badly on my thumb. Is there any possible way we can get it off and any ways how? Please don't say take it in because we don't have money.
