Ok. Was able to rotate the fuel line over and changed out the dampeners and upper and lower intake manifolds. Cleaned the intake manifold and fuel injectors. Noise is gone and the car is running and accelerating much better. View attachment 16167 View attachment 16167Great, I am having this same diesel noise and it is getting worse. I will replace the dampeners/regulators. I am glad someone has tried it and it had positive results. Thank you!
