Bad injector break a pushrod?

[rabid85]

Would a bad injector and a rough idle cause a push rod or roller rocker to break? The rough idle is only when cold and first start of the day. It sort of lopes for 2 minutes with smoke. Im getting contribution balance cylinder 1. Im running a new long block the last one broke a push rod or lifter or rocker cant remember which but whatever it is that rides on the cam and sends metal through the low pressure pump when it breaks.

I figured the contribution balance was the broken push rod but im still getting the code with the new engine and i dont want the same thing to happen again. They reused all my old injectors and im assuming they installed them in the same order which is giving me the same code on the same cylinder. The truck is a 2003 6.0 automatic. The truck always had the code and the idle problem the reason i brought it into the shop is it developed a popping out the intake (exhaust was coming back out the air filter) Considering im getting the same code and the cold idle problem im pretty sure the #1 injector is failing. It just seems odd that the same cylinder the injector is failing on broke a push rod. I dont want a repeat occurrence.

Load test your batteries, and peform ficm check procedure.

Sent from my phone that somebody didn't help me get.

The injector has no push rod only the valves have push rods.

You probably have a ficm or ficm harness issue meaning electrical. The injectors are electronicaly controled [solenoid valves] and activated/moved by oil pressure.If you kept the same ficm and wireing that may be why your problem followed from engine to engine.

The fault could be pcm related also. You need it scanned on live data to see what is going on.

I have a general idea of how the injectors work i know it wasnt anything physical from the actual injector it was something that let loose in the head. But could the bad injector cause some type of higher cylinder pressure that would damage something in the head.

I replaced the batteries before it went into the shop but they did sit for a few months while the repairs were being done.

I have a sct x3 it has data logging capabilities is there anything in there i should look at. I guess i will find out how to check the ficm and see if maybe thats my problem. Considering its still the #1 cylinder it could be something with the wiring i dont see how likely it was they put the same injector back into cylinder 1.

probably all a coincidence. Seriously, with a catastropic failure like a failed lifter and the LPOP ingesting needle bearings I'd would have recommended you replace all of the fuel injectors. Any time metal is in the oil it has the potential to end up in the injector spool valves.

I would put an injector in it and go from there. A bad injector isn't going to cause any issues other than maybe a cylinder wall washdown or melted piston.
