I found answers to a lot of my questions by searching, but couldn't come up with anything on this. I have a crack in my exhaust manifol on my 1990 with the 5.0 V8. Seems like it'd be fairly simple 3 change out (as long as I don't break the bolts off - which I'm not sure if that's a big problem on these) Has anyone had to do this before? Any pointers or warnings you mite have? I've done this on my old t-bird and it wasn't that bad... but it wasn't nearly as dirty and rusty all in that area with the threat of stuff falling down in the motor while you're messing with it. Is it a pain to get the donut gasket in these? I'm just trying to decide if I should do this project myself or break down and pay a pro to do it. Thanx for any input.
