In another thread, I mentioned that my silver Formula was making a sound indicating that it might have a cracked manifold. Well, last Thursday, on the way home from work, it got very bad. Sunday the weather was nice, so I checked it out. It turned out that the problem was an exhaust manifold gasket. And luckily, it was the rear gasket. That portion of the gasket for the cylinder closest to the distributor was completely missing. I haven't a clue how it disappeared with the bolts still in place.
So I went to the local AutoZone, and of course, they didn't have any but could special order them. So I went ahead and ordered a set just in case. But then I went over to Advanced Auto. They didn't have them either, but then my mind clicked, and I asked if they had exhaust manifold gaskets for a 93 Firebird V6. They didn't have that either, but gave me the address of a nearby store that had some. So I went over to that store and got a set. My car's as good as new now.
So remember that if you need exhaust manifold gaskets for a 2.8, and can't find any, you can substitute those from an iron head 3.4.
