Bad injector break a pushrod?
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.
