6.4 engine knocking but runs fine. Bad injector???
I was running Extreme Street tune from Innovative Diesel (285) when truck missed a step and started blowing white smoke. I let off the throttle until it stop blowing white smoke. Then I notice the engine had a knock or tapping noise afterwards. Drove the truck slowly back home wasn't but 2 miles away. I only cranked the truck twice sense then,it seems to run fine just that knocking noise. I held my foot on the brake and gave it gas it seems under a load the noise isn't has loud. So i'm thinking I have a spilt injector tip poring to much diesel into on cylinder which is making it knock. It just seems that I should get a code or engine light would show up if an injector was bad. Can anyone shed a little light on the subject. Thanks
