So today I put my new typ4 injectors in my truck that I got because I figured my injectors wher bad because of a knock and smoke. Well turns out 4 of the old investors leaked like crazy but it still smokes and ticks. Any idea what the cause is. I don't have the funds to rebuild the motor but if it needs a pump I will pay to have this one rebuilt as long as the tick/knock is an exhaust valve and not something major. Any ideas? And you can't tell in the video but the smoke is pretty thick and blue for the most part. And will randomly clear up for a couple seconds to a minute and then smoke again. http://m.youtube.com/watch?v=lyTigvdgv5k
