[Solved] Replacing CR Slat Pressure Valve in Chrysler Voyager 2.8 CRD: Procedure & Precautions

Hello CR strip pressure valve is leaking, can I just unscrew the old one and screw in the new one I bought? Will this not cause any problems with the injection or something else? And is the exchange just replacing these valves of course? And is there any fuel pressure (or high?) With the engine off?

Toto in the picture?

Yes, this is the valve at the end of the CR / Voyager rail 2.8 crd 150km 2006 /

It's a safety valve. Sometimes it fails and drops pressure from the rail into the overflow. You exchange and that's it.

Just unscrew and screw everything? something to look out for? I'm not a mechanic and I'm doing all these repairs for the first time

There will be no pressure in the rail. HE will run a little. If the new one is complete with the O-ring, then unscrew and mount the new one. Unscrewing may require a lot of strength. Lubricate the O-ring before mounting.

The above became irrelevant, today while driving (accelerating) it boomed and I lost my drive. The transmission does not transfer wheel drive. I can toggle the gears, the engine is running, the computer shows nothing and it is as if it was at ease. Some liquid has leaked out but it is on the bayonet. Anyone have any idea what this could be?
And maybe some suggestions for a workshop in Warsaw and the surrounding area?

As for the valve, I could not unscrew it, unfortunately

The valve was very badly sealed, it is impossible to unscrew it at home (without the right extension) after replacing it is much better at the beginning.

Good morning,
I have a problem with my Voyager 2.8 CRD from 2005 Classic symptoms for the fallen valve regulating the pressure in the rail - at low air temperature it stops starting. When it's warm (above +5) - there is no problem.
I ordered a new valve based on VIN, moreover, the search for this model gives exactly the same catalog number 1110010015 or 1110010018, I started to exchange.
And the problem - the valve unscrewed from the rail is smaller than ordered.

On the left the valve ordered, on the right - unscrewed.
Car serviced by the previous owner at an ASO. I have a printout of service activities - the rail has not been changed.
Wanted on the network (maybe there were other versions of the rail mounted in these cars?) Give no results.
Anyway, I have not encountered any Bosch valve that would resemble my twisted one (smaller thread, smaller diameter and other piston shape). The markings on the valve itself do not say much - there are no Google results.

Do you have any idea how to identify the model (catalog number) of such a valve?
You can approach the smallest resistance line and replace the whole rail, but for financial reasons such an idea falls away.

I exchanged such a 2.8 crd 2005 eu valve and it was so bigger. As you can see there are various markings on them. But before I bought from Lithuania through Ebay I checked the mark on the old one. There are two different factory settings and you may be able to return or exchange for the smaller one

After repairing everything else, the valve also works as it should.
