About repair of a leaking injector. In the old times for trucks and tractors injectors that were leaking, common practice was to lap the surfaces together with an abrasive compound.

That process: the out injector, tear it apart, the out the needle and pulverizer, smoke a few cigars and collect the ash, mix it with a bit of water, dip the needle in this concoction and twist it in the pulverizer. Do this for one hour or so and constantly dip the needle in the water-cigar ash solution.
Good as new

An interesting video, of course with later common rail injectors it all changes....

Great Video!
I want to replace the nozzles in my VW TDI injectors but what is the process in getting the injectors pop pressure balanced and how close do they have to be with each other?

[obet]

[mauriciodegois]

Yes, I would also suggest a table black ou brown to catch the fuel spray!! Yes, it is.

@virus56777 This is the exact procedure used in the pro shop where the fuel pump and injectors were rebuilt.

Just put your hand under it, just tickles a little.

Caution!!! The test fluid will leave the nyzzle at sufficient force to penetrate human
