Thanks all for tips. I'm wondering if pulling injectors would and spraying some carbon cleaner or something in there and trying to unstick them from the inside would help? Maybe i could fill the prechambers with diesel and let it sit?

Also, I just replaced the intake gasket last year when i did the fuel o rings. Since this is a non turbo, i'm thinking i'm probably ok to reuse it . Worst thing that can happen is a little oil leaks out and it gets black around the edges ? I'm thinking with a turbo you will have pressure and the blow out would be more severe and you wouldn't want to lose your boost pressure. Anyone reuse their intake gasket?
