So I have been trying to eliminate small exhaust leaks at the headers from the day in installed the kit. I believe these leaks are causing false readings from the O2s and for that reason I have not spent the money from refined tuning yet.
My question is this....I know that I over torqued the header bolts when i did the install. Can this be a reasonable cause for leaks at the manifold? And, knowing that they were over torqued, are the gaskets (they were new when installed less than 1 month ago) ruined? My thought right now is to loosen the bolts, and re-torque in proper sequence and to spec. I am hesitating because if I have already mangled the gaskets what would be the point, I will need to start over anyway.
Lastly, if all hope for these gaskets is not lost, are there any tricks-of-the-trade that I am not thinking of?
