I instantly first thought of engine damage, then felt hopefully only a gasket. Started with that dreaded tap, tap, tap, rapidly becoming quicker & louder, pulled over & then realized (God, I hope so) is a gasket. Limped the few blocks home, seemingly loosing power along the way & made it up my steep driveway. Is on pass. side, now very loud but with hand feeling about can't feel any leaking air nor see any discolored blow-by...real hard to tell where coming from. It's not at the downpipe to exhaust flange & don't think from downpipe to turbo housing. Guess can be header to head but I understand there's generally no gasket there, so perhaps is that doughnut between header and crossover? Perhaps cracked header, but don't see any crack.
Is there a diagnostic way to best-guess where the leak is? Don't want to tear all apart & perhaps still not be able to tell (because not many gaskets to begin with) where leak is from. It may help to know it is very loud now and car lost power.
Thanks, experienced input really appreciated.
