Ok so I have a 2004 chevy 3500 I've made a forum before about the excessive fuel in crank case and was told it's a cracked injector and it was running rough and wouldn't let you go over 2000 rpm which I changed the fuel filter and the hesitation went away and runs and drives fine now I was just curious even though one of the injectors are cracked and leaking fuel into the crank case would it still run fine or do I have another issue I have noticed it still smokes and has a raw diesel smell to the smoke which I know is a sighn of bad injector
