After cleaning out my throttle body and IAC valve on my 99 3.4l, I found an exhaust leak. Its not where the manifold meets the engine its where the driver's side exhaust meets the exhaust tube that crosses behind the engine to meet up with the passenger side.
I am having trouble locating the correct gasket that goes with that flange, its not in the repair manual and the only things I can find online are a complete gasket set for the 3.4 or just the manifold gaskets. Should I try the dealer, or is there somewhere online that does have them?
Also, since I will be taking apart part of my exhaust and replacing one gasket should I just take apart the rest to do all new gaskets?
