Injector Questions on my 300SDL
Well, my friends at Diesel Giant have me just about sold on new Injector Nozzles on my 300SDL.
It looks easy enough to do but I have my reservations. For instance, Im unfamiliar with the term "pop testing". What does that mean? Im also wondering what would happen if I did it myself...what would be the hinderances? Bozzio nozzles look like the way to go for me but I just want some professional advice. Ive read some of the threads on the subject but am unsure if they apply to my model and year Merc...times like these I ask myself..."what would Brian Carlton do?" |

You need a selection of different thickness shims to adjust the pressure.

Did you have a thread on any fuel injection issues?
If you're already sold on the injectors, we really can't help you. Pop testing allows a person to know the exact point (psi) where the injector opens...........it's preferable that all six be quite close to each other for a smooth running engine. There are certain risks in changing nozzles...........sealing the nozzle to the holder is an issue...........there is no gasket. Additionally, it would be very rare to have a set work properly without checking and adjusting the pop pressure after the new nozzle is installed. |

I wouldn't spend a dime on any new or rebuilt injector parts until you have your currant 6 tested. Their is no reason to replace them if they are poping good and spraying well. If any are not just fix those.
Buying a set of nozzels and screwing them on yourself is a waste of time and money. You have no idea if the pop pressure is anywhere close, or even if the spray pattern is good. Find a diesel injection shop, remove yours and have them tested. Take it from their.
