Hi guys,
I just installed a set of BBK shorty headers over the weekend. After 17 f**king hours of work, many pieces of painful muscles, some ruined clothes, and a whole lot of curses, the car started. Even without an update on engine tune, I do feel the gain on low end torque, and the car does sound a bit like the 2018 Mustang V8 I rented 2 weeks before. Still, they are different sound and I like both of them.
However, I was unfortunate to find out an exhaust gas leak issue from the passenger side. I can clearly hear some chirp sound at 1500-3000rpm pull. For higher RPM range the leak sound is just annihilated by the glorious exhaust sound. Worst part is the cabin smell smoky after driving a while if the AC circulate from outside.
This afternoon I re-torqued all the bolts on engine side as tighten as I could, but didn't fix the issue. I even hooked the other wrench end with zip tie and pull with 90 degree for maximum torque. So I'm sure the bolts are really tight. I also took the advice from the forum and reused the stock gasket. What can I do to fix the leak?
I heard from some one I can apply some Permatex Ultra Copper over the gasket. Can I apply those without the header taken off? I mean I guess it wouldn't matter if it is applied quite messy, since it's the exhaust part of the engine and any excessive part would just burn off? It's a real pain to take off the passenger side as you all know.
To appreciate your constructive advice, I brought some donuts for everyone, please enjoy:
