I’m looking to find how much diesel should leak back from the injectors at idle. The couple of results I’ve found on this forum are one at 0.46 ml / second. But another chap reported 0.018ml/ sec.
I’ve just tested mine at 0.14 ml/ sec so I’m inclined to think the second result is maybe off by a factor of 10.

Has anyone else measured leakback?

I’ve just seen a youtube video of a leakback test on Bosch injectors on another engine and he said if its less than 40ml in a minute = 0.67 ml/sec then it’s ok.
