EDIT: The Bosio supplier said the injector seemed gummed up, so it was my fuel. I'm not sure I agree. I'm sure all VWO mercs don't have gummed up injectors. If they did, surely we'd know about it? I use injector cleaner in each tank full.

SO now I'm not sure what to do - get Italian Bosch's or use the Bosio's in my wife's 92 300D (which I might convert to run 50% WVO single tank.)

Alastair / H.C.II- any comment on the quality of the Italian Bosch nozzles from Merlin Diesel? Did you know they were Italian?

All the nozzles Ive had recently from Merlin-Diesel have been made by DELPHI (Lucas/CAV) and made in France--These I have found to be excellent...

Ive not seen any Bosch Italia nozzles -Ever- so cant comment...

A friend has had issues with Bosch India nozzles, of the DLLA type used in Direct-Injection engines but these are totally different to the M.B DNOSD types.

With regards to the Bosio nozzle...I havent seen any yet over here in the U.K. However regarding the 'pre-injection' central hole...
This was only on the nozzle type DNOSD240/A

What is Important with Diesel-Nozzles is the Part-Number....

They are ALL completely different and will seriously affect performance if the wrong Number is used....

What Number Bosio Nozzles are you guys using in your M.B's....? --Maybe the Bosio Supplier is a Boso and giving you all the wrong type-number...

The Earlier DNOSD220 for the OM-615 and early 616 was of a solid pintle construction without side-cut.--Prone to be 'noisy' according to what Ive found out
Some early OM's used the DNOSD1510 apparently, Another 'Noisy' and probably well obsolete nozzle-Italian VM engines used these and are not known for quiet operation!

The Later OM-616 and 617 N/A Car applications used the DNOSD240/A (With central pintle-hole) Manuals recommend retrofitting the '240 in earlier OM engines if 'Diesel-Knock' is objectionable Good nozzle on veggy-oil

The OM601/2 series had the DNOSD261 With side-cut pintle..

'261 were also used in the OM-617, where its fitted to the 4X4 'G' Wagen.--These work well, Very quiet and clean with veggy-oil. Slight increase in low-end torque Ive found. Set at 115 Bar for N/A engines.

Never seen a DNOSD265 fitted to an M.B.---Thats an old VW 1600 Golf/Rabbit Nozzle according to my data!--But who knows what they used in overseas applications....
