Combustion chamber tightness

[victorl21]

Hello,

I'm building my first turbojet and I have questions about the injection tube. I'm using a Garrett turbo with a 36mm inducer. I have doubts about how to guarantee the tightness of the combustion chamber in the injection pipe hole and in the hole for the ignition electrode. Any ideas?

Thanks in advance.
