after my manifold swap on my b16, i've been having some idle problems. i found that my throttle body wasn't sealing well so i tried a new gasket. I used sealent and torqued it down, but air was still getting through. so i tried to over torque it and snapped a stud. could the flange on the manifold be warped? any opinions on my situation or tips on getting a good seal would be appreciated.
