Technical Ducato 3.0 2009 Leak Off Test

[Chris McGlinchey]

Hello everyone.
I have a 2009 Ducato 3.0 65000 miles

and have an intermittent misfire that last a couple of seconds and the engine judders and then all is OK.

I have had a new ecu, throttle body, egr valve, maf sensor, map sensor and cam sensors, all to no avail.
Today I carried out a leak off test on the injectors. 30 seconds at idle. I have added a picture of the results.

Does this indicate all 4 injectors are shot?

From my experiences on smaller Fords etc. it is how many CCs over so many minutes, so possibly a bit excessive, I can't recall exact amount. I was looking for one noticeably higher than the rest, mostly on cranking as non runners with no common rail pressure due to one duff injector.
Just a thought in the download section there is a Iveco engine pdf download which may give correct measurements as same Sofim engine.
I wouldn't have thought this was the answer to your issue, but maybe some has more current personal experience, especially with only 65k for a commercial engine.

Looks like cylindar 5 will never run.
