Long story short, my donut gaskets are leaking on both sides, I had used exhaust cement while installation and had made sure it seated straigh and also that flange was torqued evenly...
I had tighten bolts some more and now I have even bigger leak...
I do not have springs on the bolts (it was like that), but I see that some do...
Do I need to put springs on?
Also is there only one dimension for gaskets and which? Because rockauto has 2 or 3 different dimensions ...
Any other tricks for installation?


Thank you
