Injectors in Acetone

[dufflespank]

I pulled my injectors this morning and they are quite dirty. I took them apart and submerged them all in acetone; I'll probably take them out omorrow. It just occured to me though, are there any components in the nozzle that may be negatively affected by the acetone?

No. I use acetone, it's fine for the injector bits; not so good for your liver.

Make absolutely sure you keep the nozzles with their matched nozzle body.

Acetone is fine. You can also clean them with a brass wire brush, don't use metal.

I was thinking of cleaning mine also, are there any pieces i have to buy when reassembling them? O-rings?

Any torque specs?

PS: OM601 engine

[dufflespank]

Is the torque spec between the two injector halves the same as the torque spec between the head and the injector?

Read the book. Acetone is probably a waste of time and money.

Diesel Purge?

I soak them in marvel mystery oil. but there's never any difference... so I always end up taking them to the local diesel shop and have them tested.
cleaning (unless ultrasonic) will have pretty much no effect whatsoever it seems.

Bosch makes a cleaning kit; I use 0.08 and 0.10 mm. dental instruments under magnification.

Which part(s) of the inectors are lapped? The reason I ask is that they leak pretty bad (from the center), and I'm starting to think that the "lapped" threads aren't sealing correctly. Now that I have them apart, I would like to do everything correctly the first time.
