Everyone gives so much for this engine, I think Citroen would not screw the screw at 27Nm - probably a bit too much, and there is a long and quite thin screw

madamsz1 · Answer

In Ford, this engine has 4Nm +65° - 1.6 tdci PSA

cichy koksik · Answer

I just read about tdci engines, but I don't believe that there is so little in my engine because it is now tightened at ~ 27Nm and somewhere on the forum I found such info, but I would prefer to be 100% sure.
I will add that the injection system is Bosch.

madamsz1 · Answer

With Siemens injections, Ford gives 7Nm and 85°. How in HD? I don't know. 27 is probably too much.
Lemon gives:
Injector mounting flange nut:
Pre-tightening 0.5 ± 0.1 daNm
Angular tightening 65° ± 5°

@madamsz1 @WloczykijMalaMi But gentlemen, there is no nut there, only an ordinary screw and it seems to me that this moment given by you is wrong.

cichy koksik · Answer

If this is from my car, I'm very surprised, but also a little bit disbelieving

WloczykijMalaMi · Answer

I compared in four different places, including information from Citroen with what I found on the Internet. The last option is a purchase for information on the manufacturer's website or from a person who makes Lemons every day. I won't help any more :)

cichy koksik · Answer

Well, the problem is that I fix it myself materials are not available for free for this car. What's more, in c4 II, the entire injection system is slightly changed, there are other lugs and other mountings. Anyway, thank you for your help On the other hand, if someone tightened the injections and it should be as you write, nothing but cry.

cichy koksik · Answer

Okay gentlemen.
You were right - 7Nm +80°
The data comes from a citroen service from a kind college from another forum.
I'm looking at it now and I don't believe it

But someone smart must have screwed it up

And so now I will rummage with the injections, so new washers and sealing will go.
Do you think the bolts should be replaced too?

madamsz1 · Answer

How they were so dragged for sure

WloczykijMalaMi · Answer

Screws are a must, don't even think about it.... :D Regards, WIM

cichy koksik · Answer

How about the paws? If they're durable enough, they're probably indestructible

WloczykijMalaMi · Answer

I will write this if you are to have trouble from the client later and you see that, as you wrote, someone turned the wrong way, then there is only one answer. Regards, WIM

cichy koksik · Answer

I am the customer

In general, I pull out the injections anyway (me or the mechanic because I don't have a key with such a low scale) to check / regenerate, so I would like to do everything right, but I don't want to buy something that is not necessary.
I will pay for the recovery itself

Maybe I will visually assess the condition of these paws because buying replacements may not be a good idea.

mariuszgawor · Answer

maybe late for the answer, I did so 7nt 80 degrees and it's ok, the first time I turned by feel the broken paw holding the injection and not immediately, only after some time, I only realized how the inside smelled of exhaust fumes
