Good luck from your Grumpy Mechanic ;)
PS... Sorry for mainly using English Language, the reason is mainly that im working and doing everything in England.
I rebuilt wife's 2007 C4 with the DV6 engine. The injectors would NOT come out!! Had to remove because one of the glow plugs snapped the tip off :-( Ended up cracking off the injector from the nozzle cap nut on each injector & spinning them out. Then had to drill out all 4 cap nuts , which was nice!! Then had to clean up the injector seats. Then had to replace 3 of the injectors (Darwen Diesels supplied recon units for around £120 each and their service is second to none!). I rebuilt the engine with new head gasket kit, new full seal & "O" ring kit, new timing belt, new timing chain, new glow plugs, new water pump, new oil cooler, crankshaft oil seals front & rear, new clutch kit (the original reason the engine came out was because it has the piloted gearbox and it started, jumped forward & stalled, despite the fact it was in neutral.... I believe this gearbox doesn't have a neutral as such, but the electronics hold the clutch in a disconnect state until you rev the engine, In our case, the crank seal had failed & oil had contaminated the clutch lining, causing issues the computer couldn't adjust for). When I checked the EGR, I found it was immaculate, probably because I forbade my wife from using shite supermarket diesel, but chose BP Ultimate instead. The turbo was also in excellent shape with no play in the shaft, no doubt thanks to the removal of the banjo bolt gauze filter and regular oil & filter changes (5k miles approx) because this car does short journeys.
Now it has been a couple of weeks since the build, but we cant stop the diesel leak on No2 (French count No1 at the flywheel end) which is the original injector. I have tried new copper washers, testing for leaking fuel & leak off pipes (no leaking detected), but always the fuel just builds up around the injector. Thought perhaps it's the seat, so got the tool down there, all good, STILL leaking! There is no chuffing, no bubbles and the engine goes well. The car can reach 100mph in seconds (I think it was mapped before we bought it as it just seems insanely fast). No warning lights, no obvious signs of problems.... So I can only imagine the problem lies within the injector itself. Has anyone hear of these injectors (Bosch) leaking from the top despite not having been stripped? Is it possible the body could have been damaged when the spanner used had to be forced hard to break the seal of the cap washer (the same that had to be drilled out once the engine was out).... I'm at a loss to find any other cause!?!?!
I'm planning to buy another recon unit, but would like to know the actual cause.... Thanks for reading 🙂
Thanks for the video. I had that same fault develop on my 1.6 HDI Berlingo B9 over the last few days. Lots of exhaust smoke in the cabin compartment when stationary and chuffing noise which got worse over two days. Didn’t help I drove from Sussex to Glasgow like that yesterday.
After viewing a few videos I watched this one and sure enough when I checked the car the same injector bolt on the far right (is that cylinder No. 1 or 4) was very loose. Nipped it up for now and almost cured.
Lots of oil around the injectors so I’ll change the seals on those that will come out and I’m sure will be a vast improvement.
Car is at 158,000 miles so I had visions of scrapping it before this fix. Well done mate and thanks again.
Yeah unfortunately it does happen often 😞 but we'll done for looking it up and fixing it 😀
Thank you for the feedback
torque : 4nm + 65° (65degre tighten)
Thank yu
you r welcome
I have a 2007 Xsaru Piccaso HDI 1.6 80kv 109 hp and I have this problem 1.6 HDI injector leakage and noise and I'm just interested in how many newton meters you tightened those two bolts
Hi there. That needs to be looked up on Autodata or similar program unfortunately
Hi Alex...when I done an oil change today I noticed the first and fourth injector had a small leak at the seal area...so I got my 8mm bit on it..think it was 8?...they were both loose...the ones at the back were rock solid...so just front 2 on mine..thanks for tip man.
Nice one mate! Well done. It's very common unfortunately. At least it's done in time mate. Thank you for support :) Subscribe and share if you don't mind :)
Hi Alex, I replaced injectors at local garaj and this problem started (one month post replacement) I took back to Garaj, he tightened again.. it worked for a while and noise is back on as well a fuel smell inside the car... My mechanic is afraid of tightening the bolt as he feels it could break.. do you have any alternate solution or fix to this? I live in North London
Hi there. I would get new bolts and washers first. Also I would check the thread for any damage
Great video! I'm off to see if that will fix it.
Thank you 😀
Is it possible for the 1.4hdi do be the same as I've the same noise when ever the car to warmed up
It can happen yes
@@AlexTheGrumpyOne and the car has no boost like it has loosed power is it possible that its the same problem bearing in mind theres currently 210 thousand miles 😆 thanks for your help 👍
High mileage 1.6 HDI's get louder.
Hi Alex, great video....I think this is what's going on on my Citroen Picasso TDI 2 litre. The ticking sound goes after two or three miles but it's there on startup and only started two days ago. Sounds exactly like in your video.
I'll get it checked but is it ok to drive the car before the mechanic can book me in as I have two 70 mile trips to do?
Thanks for your video!!
Hello there. Thank you.
It depends how bad it is. Can you see anything around the injectors yet? Like fuel or carbon?
If not then it should be fine. But I would advise to sort it as soon as possible before it builds up a lot of carbon.
i have a 3008 10 plate numder i hot lots ofd white smoke coming fron muber 2 injector and its moveing . ive just not long got it back, they put new ones in. please can you advice me thanks
It's probably not done up properly or a seal is damaged under it. You need to take it back as it's a warranty job
@@AlexTheGrumpyOne Thank you for getting back about my problem. i was thinking to d.i.y.. but has there new like 345miles old amd i might as you say the warranty so thought best leave it alone i have had a tow truck to take it back, thanks again for your reply.
Yes that would be the best option to be honest. As if you try and do something and it's still no good they not going to accept it afterwards
hi Alex! I have worked out something about my engine problem, the rattle goes away when I use premium fuel like Shell Vpower and the noise goes away, it seems to still rattle when the fuel is getting low but it’s no where near as loud as it was before. I tried the wynns extreme injector cleaner but this didn’t seem to fix it with 2 bottles in 2 tanks. The Vpower is working to stop the rattle so I guess it’s detonation of the diesel randomly or something maybe from carbon build up.
Hi
I have a Citroen C4 1.6 HDI 2007 . Last 6 months i have problems with the injectors . Even though the injectors have been calibrated and are fine the car rattles under load. I found coincidentally that I also have an electrical problem. There is a voltage of 9.9 volts at the lights without the lights on, without the engine running with the key in the on position. When I turn off the key switch it lasts about 1 minute (as long as the BSI standby) and then stops. I think there is a problem with the COM2000 but im not sure.
By diagbox, i found F522 and 7155 (It appears when I turn the switch to on and disappears when the engine starts)
Have you seen anything similar?
Is there any way to check the light switch without removing the steering wheel?
I'm starting to think the injectors rattling is coming from some electrical problem in the BSI.
Any idea what it could be??
Hi there. I had a similar fault on a clio before and it turned up that the A/C sensor under the bonnet next to the radiator was dragging voltage.
@@AlexTheGrumpyOne Thanks for the tip. I will check it today.
No worries
@@AlexTheGrumpyOne I looked at it yesterday, I only found one pressure sensor but that's not the problem. I have to keep looking elsewhere
Hi very good instruction. I have the same problem. I could smell the fumes from the injectors, putting my nose down close to each one of them. I've tightened the bolts, two times now, to around 9,9Nm and one still smells a bit. I was able to tighten them a little more every time. Do you think another tightening check would be helpfull? Thank you very much
Your welcome.
Yes I would suggest to double check if for you engine code the torque is correct. Might have different torque settings
@@AlexTheGrumpyOne Thank you. It might be a little lower the torque im using, just for safety. Found one place that said about 15Nm. Do you tighten the bolts when the engine is hot?
I'm a bit afraid to break the bolts
@@susannepedersen3727 yes I understand. You do need to be careful with them.
@@susannepedersen3727 Thats seems right to me. I like to do them when its not hot. I know it does change and expand and etc when hot. but i usually like to do it when cold. its not a massive amount of torque, so should make that much of a difference.
let me know how you get on :)
Perfect tips now is my girlfrend's citroen ok, and she is impressed ower My mecanic skils :)
well done :) got your self a brownie point there!
thank you for support
We have this same issue except there is smoke and the two middle injectors are completely black. Any idea?
It probably will need new ones at that stage mate. You got a video on it?
Ill try and get one of it. What could i send it to you on??
@@illegalfreedom1055 you can send it on Facebook if you got one mate. Search for Alexthegrumpyone on Facebook ;)
How did this go?
my citroen c3 1.4 is leaking diesel ..could this be the same issue??
Yes it is possible. But make sure it is not too bad. If you got carbon there already then you need to clean it first
Hi Alex, unfortunately I don't understand English well and I didn't understand the precautions to have to tighten the bolts ... can you write me that I can help with a translator?
Thank you
Mauro
your welcome
great video going to check my injector clamp bolt today too, would you happen to know the citroen c3 mk2 2011 1.4 hdi injector clamp bolt torque settings?
Hi there. Thank you. I will try and look it up today.
@@AlexTheGrumpyOne thankyou mate, really appreciate it, if you need car reg or vin I can provide that for you.
Hi sorry I haven't manged to get to the workshop unfortunately
@@AlexTheGrumpyOne no worries Alex, I'll try the citroen fourm, hopefully some bless soul can help. again thanyou very much for the video, you've helped alot people out.
Not a problem. If I get a chance to pop in there I will definitely look it up ;)
Thank you for the support
@AlexTheGrumpyOne Did your method, after all, work?to stop that noise??tnx
Yes mate it did. Usually 9 of 10 works well. Only if people leave it well late to look at it and it builds up carbon and etc then it's more complicated.
Tommorow I will try,
and the last question, how strong should these screws be?And tnx for answer mate!
@@ilianame I can't remember the torque for it at the moment as I'm away on a Toyota course at the moment. But can look it up when I'm back. Or try and search torque setting for them please
Hii have a 1.6 citreon xsara picasso hdi it has a ticking noise in tick over and fumes in the car wondered if you had any ideas.
Ticking is the internal issue of the injection. When was your fuel filter changed last time?
@@AlexTheGrumpyOne I dont know only had the car two weeks and same time as ticking noise fumes smell in car exhaust fumes smell
@@detectingnottingham9952 I would suggest changing fuel filter first and using dpf cleaner additive if your one got dpf on it.
Is your fuel consumption ok?
@@AlexTheGrumpyOne according to in car computer I'm doing about 54 miles to the gallon
In car computer says 54 to the gallon
32nm! Really? It’s like an m6 bolt?
Only following the instructions mate. Can't do anything about it. It does seem quiet a bit to me ..
I can only find reference to 7nm then angled torque by 65 degrees? So about 14nm? Where did you find the info on 32nm, mine is a mini d same engine though.
@@JustinHT I'm pretty sure it was on autodata. My boss gave me paperwork and I've done it mate ;)
I have no idea where did you pick up that 32nm value for m6 thread? On ford cars with 1.6tdci (hdi) that value is stage 1) torque to 4Nm , stage 2) angular +65° !!!
Like i said it was what I was supplied with by my workshop
Hi i have a Volvo v70 1.6d 2011 with a ticking under load not when it’s idling. Like pre ignition sound and it seems to come when it’s warm and under acceleration. Any idea what is could be? It doesn’t appear to be leaking around the injectors or anything like that but it is a worry for me. Any help would be great thanks
That might be bad injection or injector issue. I would recommend using fuel treatment. Injector cleaner .
Unless it's bad diesel or mixed fuel.
Has the fuel filter been changed recently?
AlexTheGrumpyOne okay I will try filling the tank with the premium diesel and a bottle of the best injector cleaner I can get and I only bought the car in January but it has a lot of history but nothing for the fuel filter so I assume it’s not been changed recently if at all... is it easy to change?
AlexTheGrumpyOne also sorry for the extra questions, 1 more only I promise. Is there a way to test the injectors at home if the expensive diesel and cleaner doesn’t work? Also it seems to drive well but the ticking is there. Fuel consumption seems normal as it doesn’t use a lot usually around 50mpg or just a little less
That would be a good idea.
I would recommend to replace your fuel filter first and new fuel and treatment. To be honest I can't remember what it's like to do fuel filter on them. It's been a while and a lot of different cars since then.
If that doesn't help that I suggest getting it plugged in with good diagnostic tool and looking at live data for the injection timing and quantity to see if any of them are out of range.
No problem buddy.
Yeah I've pretty much answered that question in my last reply. Plugging good diagnostic tool and looking at live data.
Please let me know how you will get on with it and if fuel, treatment and filter help first.
Good luck buddy
Great till the annoying person tooting the horn ..horn test ?
Yea unfortunately had people that didn't like me doing videos ...
I fix mine every month idk why
U need to clean it properly and then use new bolts
@@AlexTheGrumpyOne ow thank u for responding brother will do thank u
@theempire2805 no worries. Good luck
