I sound like a broken record but...... Make sure the ALDA lines are clean from the manifold back.... IIRC it's a 10mm socket to pull (nope now I think it's a 14mm
) the nipple out of the manifold that the ALDA's rubber hose connects to. A large pipe cleaner and solvent work well. There is a green plastic connector(after the manifold before the ALDA) that has a very small orifice that clogs eaisly. All the small hoses and that green connector need to be cleaned. I used brake parts cleaner and compressed air. If the ALDA doesn't get vac it won't do it's job. Kinda like cleaning the banjo bolt on a OM617
If that's all clean, then it's over to other side and the dreaded "rats nest"
Which I always kept clean and working

I'd also recommend disconnecting or blocking-off the EGR valve; if it has failed in open position, it will cause lots of smoking. Even the smallest disruption inside the pre-chamber can cause the combustion process to be incomplete and smokey and noisey.

I concur....
