Mate, same problem as you, did you get an answer yet? Mine was so bad it’s also blowing white smoke ( unburnt fuel ).

I just created a poll to have and ideia which cars have been affected.

Please help collecting the data and cast your vote.

I skimmed through, but did not see the part number of the injectors by Siemens?
All L76, L98, LS3, L77 and LS7 are made by Bosch, GM part number 12576341, never heard any complaints with several hundreds of thousands of km heavy duty. Bosch ID# 0280158051 42#

Got call back today, Holden are replacing all 8 injectors under good will. Also got told I have a bent pushrod in cyl 1.
I know for a fact that was not done by me, car has always sounded a little rough, now I know why.
Car should be back on the road by friday

OK, I think Bosch make the injectors just like the spark leads and O2 sensors, NGK make the plugs, Cloyes make the timing gear, Delphi makes the lifters, etc.
I think they are all available though AC Delco, which used to be a division of GM like Mopar or Motorcraft.
Can you tell me the date mm/yy of your car manufacture, as it seems the injectors you ordered supersede the Series II VE and perhaps it is those which are now causing problems through failure.

Thanks for that, just trying to nail down the break when the (non-failing) injectors were revised from 12576341 to (failing) 12639221.
Seems it was 2013 model year, assuming your old injectors are same?

Just another poll to see if there is a trend on which injector is falling

Just read “bent pushrod” on a factory motor with hydraulic lifters and low ramp cam... nup. Did you have the rockers replaced per chance?
