Are there any parts hoarders out there that has Jetfire stuff you don't need? I am looking for all these valves I can find. This valve is going to be a problem in the future. We have a solution to most every part to the system other than these. Jim Noel had some of them sand cast many years ago but nearly out of those and these days is simply to expensive to have done again. Don't matter if yours is good or bad, All of them need rebuilt. Even NOS ones are bad. We just need the cores.

Maybe in the future we could 3D print them but the internal machine work will still be really expensive.

 

Good luck finding some. Have you searched modern cars with turbos? Maybe a modern part could be reengineered to work.? I'd search on diesel trucks in the salvage yards and in the forums.

 

This is specific to the Jetfire. The 63 Corvette with the fuel injection has a valve sort of like this but still not the same.
