Sorry if I am using incorrect terminology. I believe the head flange gasket is broken.
I was hearing an exhaust leak type noise when accelerating. Hooked up a shop vac to the exhaust and blew air in, found the air hissing out around the passenger side valve cover area. Initially thought it was a bad valve cover, but eventually realized it was coming around the header. You can see the, what I think you call?, head flange gasket is broken. That is where the air comes out.
I've attached some photos. 1 of the damaged area. 1 of the a wider view.
I am not too mechanically savvy, but really enjoy learning. DirtDonk has been helping me through all sorts of projects on my new Bronco!
Can I just unscrew those 8 bolts, pull out the headers, pull out the damaged gasket, replace with a new one, and screw the 8 bolts back in? Or is there quite a bit more involved?
I haven't seen any set ups identical to mine, but I have been reading a lot about the valve cover screws needing a certain torque and order of torque. I had to unscrew two valve cover screws to move something holding wires to get down in there. Would be nice to know if I need to do something to the valve cover now as well.
