I was driving my '68 Firebird 400 to work yesterday & thinking myself how well it was running while on the highway. As I got off the highway & onto the surface streets, I suddenly had a big misfire issue which required me to keep the RPMs up while at a stoplight to keep from stalling.
I limped the car the last mile into work & took a look under the hood after work.
Car suddenly has 0 PSI (no compression) in cylinder #2, with an obviously very rough idle, and a clunking noise. All other cylinders have good compression. I had the car towed home & took a peak under the valve cover for cylinder #2.
In the attached photo, there's a piece of orange rubber (one of two pieces I found), and also some metal fragments at the base of the valve spring for cylinder #2. I removed the rocker arm to make this easier to see.
Any ideas what the issue could be here? What's the best course of action? Remove the heads right away, or try to fix the issue with the heads still on the car?
