Damaged how badly? disturbing happy injectors opens a real can of worms...

Hello Phil the rocker cover had the small hose at the cam belt end broken off. To change the rocker cover needs the injectors removing I did this to change the cover and as you say it causes problems, so I have removed the injectors again to change the seals. Total pain in the butt, but I am nearly there now. Cheaply made modern motors for you. Baz
Did you put them back in the same cyls, as they are coded?
Rory thats a fun job to do. Not trying to teach you how to blow eggs but did you change the copper seals that the injectors sit into, it must all be squeaky clean as well.
Still have not got mine running 100% but van had been involved in a knock when I bought it. Engine had been well and truly bounced around the engine bay with all mounts broken and various cables chopped. I have been busy with life but need to get back onto the van.

Hi baz,
Yeah everything got changed and was scrupulously cleaned. New copper injector washers plus the small black Oring that sits half way up the injector. Got new rocker gasket obviously and the kncok out and push it gasket/seal that the injector goes through. Bought new stretch bolts and the 2 rubber seals that these bolts go through in the cover. I made sure iv had everything to hand to do the job, everything tourqes to spec too as per autodata. Injector seats cleaned to so I could confirm that seated correctly.
It's a shame youve never gotten to the bottom of it. Reading through some threads on here there seems alot of talk that once the injectors are disturbed they seem to pack up. Iv never experienced this kind of issue before and typically I would happen to mine.
I released the injectors even though they went back in the same order just to be on the safe side but this was to no awail. Anyway, 100mile in now and it has improved but its still not perfect. Debating pulling them back out after a full tank of decent fuel has gone through it if it hasn't rectified itself and sending them to pf Jones for testing.

Did you ever get this resolved Rory? Decently replaced my rocker cover gasket, injector rocker seals and all injector seals all genuine parts fired it up and low an behold between 1200rpm/ 1400rpm it has a very apparent misfire, I did get a code; P100600 Torque Difference Cylinder 3 Limit Value Exceeded so ordered up a new delphi injector as the values was out of wack. Cylinder 1 & 2 values are -28 -40 where as cylinders 3 & 4 Values where 34 & 42 but figures where fluctuating massively.
Had horrendous injector knock under acceleration coupled with the rough running and been down on power.
Going to try some G001790M3 diesel fuel treatment then go from there.
Just thought I would ask the question to see if you got to the bottom of it
Sometimes if it ain't broken don't fix it I read this post before I started and nearly didn't do the job wish I bloody hadn't now!
Let me know how you get on i recently had the code p100500 for cylinder 2. Changed injector and still came up with same issue has very rough misfire under acceleration especially cold and blows a cloud of white smoke calms down once it’s warmed up to temperature but still has a knock slightly on acceleration so misfire still there.
I will be carrying out compression test this weekend to see how we get on. Will keep you updated
Hello there, I got rid of the code on cylinder 3 however still hear diesel knock and have a very misfirery engine between 1200-1400rpm regardless of it being cold or up to temp also more so in 3rd gear and above you can really feel the engine pegged back on performance so just nursing it currently.
I've ordered a full set of Delphi injectors as no one was getting back to me on injector deviations/ cylinder torque etc not cheap however you should never disturb a happy fuel system so I was told I wish I had just left the oil leak
It's got the VAG Fuel Treatment in there to as it was a pittance and thought I'd try my luck knowing it wouldn't make matters any worse
I hope you get to the bottom of yours but keep me posted
Just to add also, I was watching a darkside developments video on the T6 platform the other night and they have had brand new Delphi injectors Dead out the box so just bear that in mind to
I have bought the same stuff I believe VW Diesel Additive but I put in injector cleaner from another brand beforehand it didn’t do the trick hence why I purchased a new injector. My friend recommended me to swap the injectors around before digging too deep in opening up the engine. As like you mentioned about dark side development injector may even be the issue. The code you had was it as simple as clearing the code off or did you have any work carried out?
Also I do feel as if the misfire remains especially in gear 3 onwards
What makes me think it’s deeper than the injector is have a quick look at this video on YouTube about a T6 misfire.
Will deffo keep you all in the loophole. What bugs me is on a cold start when I make my journey the vehicle smokes like crazy puffing white smoke as I accelerate calms down once warmed up.
