Hey guys,

So our 220 has had a knock for awhile, when it idles it varies in volume like tah tah tah tah TAH TAH TAH tah tah TAH TAH tah tah tah kinda loud and metallic sounding... The only reason I decided to really look into it is because we just had the injectors replaced, got the car back yesterday hoping it would fix our smoking issue because she threw out lots of smoke.

Well we got her back and the knocking almost seems a bit louder to me, and she still throws out lots of smoke as well, some white smoke I saw with lots of black. I was thinking of doing a diesel purge but is that even necessary since the injectors are new? I've looked a lot more into the issue and all i'm really seeing that knocking is mean impending doom

Have I come to the crossroads of this doom???
