To start things off first I have a 2jzge Na-t with a single and some goodies. When I built the motor the injectors really didnt fit in the runners as tight as I hoped they would. I read some 2jzge na-t threads and it was said the injectors dont fit very tight but wouldnt leak. I had one seal rip and leak a bit of fuel so I replaced it and I guess while I was putting the rail back in with the injectors the #5 bottom seal on the runners got kinked i had though. I knew there was a vacuum leak at the runner seal on #5 but I was just so sick of working on cars I said screw it cause I running speed density so a vacuum leak doesnt really affect driveable or AFRs much at all. I finally got around to looking at it today after work.
I already took the squished melted part off before the picture. Obviously I need a new injector but I guess I can drive the car since its been like this for who knows how long. The biggest question though is, how does this happen?
