Truck has strong fuel smell from exhaust. No smoke at idle.
Occasionally will white smoke at wot or will not smoke at all.
I know i need injectors.
Truck has a slight chop at idle.
Maybe slight miss.

I did notice residue on my rocker box around my feed tubes. What would cause this?

 

[farmerbrown]

This is around most of my feed lines

retorque the crossover tubes, and the lines.

 

[farmerbrown]

Would original lines and tubes loosen over time? I have no clue if injectors are original or not

 

[Killer223]

my previous statement still stands.
they could leak, yes.

Replace injectors and tubes with NEW ,
THEN torque tubes.
