Well, I *think* I fixed my crossover leak *knock on wood*

I just unbolted all but one bolt of the front header and one bolt from the crossover.

Then I tightened the impposible-to-reach bolt as tight as I could with the wrench, then put some copper RTV around where the leak had been.

Tightened the other bolt down hard, smeared the RTV a little bit, fired it up for a second just to see if the pressure would blow it.

Nothing happened so I think I will be good to go tomorrow.

Maybe, MAYBE tomorrow I'll get under the car again and put some copper RTV under the band clamps on the Y-pipe so I can seal that a little bit too.
