Attention 1.6 hdi owners - read this

[Lewis G]

I've just come across this thread. I have a 57 Berlingo, a bit worried about the consequences of nuts coming loose. I don't have a torque wrench but thinking of getting one of these, http://www.thanettoolsupplies.co.uk/prod...driver-7mm

Better than nothing, any thoughts?

Hi!
Today I checked injectors again, everything looks tight and dry, I also put some white paint on each bolt at 12 h so I can check more easily next time.
I also removed oil cap and peeked inside, I don't see any carbon deposit but oil doesn't look nice at all - it is all black. Is it normal 4000 km after oil change? cratch:

It is on a 1.6 hdi! I have never seen a diesel dirty the oil so quickly as the 1.6 engine. The 2.0 hdi oil never gets as much carbon in it as the 1.6 and like i say no other diesel does and that includes hgv's and plant.

It would seem the 1.6 holds the carbon in the engine instead of letting out the exhaust - for this reason i flush all 1.6's when i change the oil, something i do not like doing or do with any other engine.

Hi guys, what bolts exactly do i have to check?
Can somebody show the picture?
thanks!

Bolts holding injectors in place. Each injector is retained by 2 bolts, one in the front, other behind which is less visible. You can see it if you click on the image in my message from April, 1.
You must remove plastic engine cover to see it on your engine.

Hi there all I am new here and I have 15 years Citroen experiance so I would love to help you all.
All DV6 (1.6hdi) engine turbo failures I have seen have been caused by injector carbon leakage due to the injector bolts being loose, Not sure why they come loose possible heat cycles of the copper washers not sure. Anyway if you have a DV6 engine check your injector securing bolts tomorrow I guarantee you they will be loose. I have done best part of 40 turbos on these engines and to all my customers I recommend a full engine strip down and clean because the carbon (looks like coal) leaks from the combustion chamber up the injector tube and destroys the little seal between the cylinder head and the cam housing, It then goes down into the engine just where the valve springs are which smash it up and mix it with the oil. It then makes a real mess of the oil and blocks the stupid little filter on the turbo feed pipe on the banjo and starves the turbo of oil and "goodbye turbo." Fitting a new turbo will not last long i've seen a car come to me which has had 4 turbos and I'm sorry to say if you have this problem the only real permanent fix is to strip the engine' remove the injectors,cam housing,oil filter housing,sump,oil pickup in the sump,oil feed pipe,oil pump and cleanwithin an inch of their lives, Personally I would do the injectors first as they can be a real pain to remove as the carbon can sieze them in solid (ps the carbon softens to a treacle when very hot so the injector removal is best when the engine it super hot and I mean super hot) we leave them running for at least 4hrs at work. Anything i have missed let me know and I will fill in the blanks. PS you will need to recut the injector seal mounting faces in the head as when they leak combustion the leak cuts grooves in the seating faces and the new injector seals will not seal.

Looking at the new type injector bolts on the latest 1.6 hdi's it does look like the penny has finaly dropped!!!!!!!!

but like you guys say it took them long enough!

i think the problem could be that the retail garages dont generally see vehicles over 3 years old. If a main dealer gets a 5 year old vehicle in they all think its a nail and no one wants to work on it!

I was chatting to the tech bloke who did my service today.
He seemed to know what I was referring to before I said it.
It seems the long and short of it is ,like polar suggests,the penny has dropped and is signified by the different fastener types pictured by Pigeonpost/drazen and myself.
He says for the latter type its no longer a worry but for the early ones keep an eye out for the blackness/moisture
Leaking will also be audible over the normal engine noise.

This has been an interesting thread- informative for us and lucrative for tool suppliers!

"He says for the latter type its no longer a worry" Should I be checking the ones on my 64 plate Berlingo?

Spookily enough........

Last month I was reading a 'theory' on another forum that the injector clamp bolts on the HDi are of the 'stretch' variety as the book says tighten to blah blah torque then add an extra quarter turn. I have no idea if that is true or false but it did get me looking at the injectors on the 110 HDi in the Mini.

Number three (counting from cambelt end) has always had a leak. Renewing seals did nowt. Reaming the injector seat, new seal - still leaking but much less. So got in a new set of bolts. Pulled the old ones - on #3 the threaded part that goes into the block was full of oil/crap, after cleaning out as much as I could stuck in a new pair of bolts, another new seal and reclamped. Couple of hundred miles later it's all good.

That engine is now at 133,000 miles and the paperwork suggests that from 100,000 - 120,000 miles it was not well cared for - in particular no EOLSYS fluid is listed anyplace after 75,000 - guess I reap the benefits   

Previously (i.e. for years)I'd just nipped up the locking nut on these if they seemed loose - thinking about it that would maybe just tighten the nut down onto the top of the clamp and not have any effect on the portion threaded into the block so not tighten that if it had been working loose - does that sound like a theory?

can the new improved fasteners be retro fitted to the older m59
