DN0SD297 Nozzles... 185Bar Open Pressure
 

I have a new set of injectors with DN0SD297 nozzles on them, they have an open pressure of 185bar... what do you think is the correct pump timing advance for start with? 1mm? more?

I would start at .9mm.
Why 297's? I haven't heard much about them, although I do have several sets waiting to find there way into some injector bodies.

I set to 0.95mm, i will try to start engine tomorrow.

I've read engine runs smoother and sounds quieter with those nozzles, better emissions too, some people in german forums talk about them.

Hi,
here is a german guy having two D24TIC with 297's. One is equipped with Bosch's original version, one with Henzo's. Both are running very smooth with these nozzles; I'd say you made the right choice. ;)
Henzo's rebuild are made in Italy, in my D24TIC I've used them now for roughly 40.000km and they are still working fine. On a Golf III AAZ I was using them for I don't know how many kilometers and had no problems with them.
Bosch is original quality, I think there has nothing to be mentioned. ;)

Good to hear about it! Thanks
I have not tested them yet, i waitting for the big torque wrench arrives for tightening the crank bolt...
This engine needs a lot of special tools for doing the job correctly. Luckily I had all the tools in my garage, but not the Hazet tools for valves nor a big torque wrench.
I've received the Hazet tappets tool past week, i think i will have the torque wrench tomorrow... I can not wait for starting that engine!:D
I wil tell you about how those injectors work on this engine,
Best regards:)

I had no time yet for trying to start the engine, i've tightened the crank bolt today with the help of the big torque wrench to 460Nm + thread locker... holy cow!:eek: that thing is really tightened!
I will try to start the engine tomorrow...i will tell you:)

That lime green is nice.

I found something very similar, ``John Deer Green`` , suggested on Agriculture Machinery.

Good idea on Volvo tool #9995187
:)

Thanks!
I've started engine finally, it starts almost inmediatly! the engine sound is great too, i'm very happy:) I will try it tomorrow and will post my conclusions about it but seems working really fine. Thanks for your help

I've tried several timing advances past days, engine did smoke white with 0.95mm. I finally set to 1.10mm, surely pump is not in perfect shape and that's the reason why it needs so much advance, but engine sounds and run perfectly there. I've tried more advance but overall impression was bad, 1.10mm seems fine for that old pump+higher pressure injectors(185bar).
Engine still having a gray/white haze that does not dissapear with the smoke screw adjustment in the pump. Engine is not missing coolant, and smoke has not blue colour and smells like diesel. I found that two exhaust valves have not clearance at all, meaning that they never be closed at all...
do you think that compression lost in two cylinders through the exhaust valves can cause the unburnt fuel make that haze?
or it will be a worn pump instead? Engine pulls nicely, sounds great, idle is smooth.
I will ask for adjusting discs on a vw dealer tomorrow...

You may find certain spots on your engine calling for the thicker shims; so switching over a few of them is an option to experiment (stay within specs), if you have the time.

FcpEuro has new shims available, not expensive. https://www.fcpeuro.com/products?key...20valve%20shim
