I have leakage from cylinder #1 and #4 on my engine. The engine has almost 120K miles.
Both local mechanic and official dealership told me that all 4 injectors should be replaced due to mileage. And the price is huge higher than my car value.
After some research and Reddit post I decided to replace the two copper seals by myself, but I afraid to mess it up.
Here some YouTube video I have watched

The parts I found on jagbits.com

Here are my questions:
1) what materials/degreases should I use in order to clean the carbon buildup?
2) Should I use anything to loose the bolt? I afraid to break it during opening.
3) How should I clean the injector when there are out?
4) What is the torque value for the injector bolt?
5) In case I will discover broken injector, should I replace all 4? Does it require any calibration for the new injectors?

Thanks!
