The guy did say they looked bad, reconed that they all would a need refurb. I think if you can get away with a refurb, then that would be a result 👍 Quote Link to comment Share on other sites More sharing options...

He was vague in regards of cost, until they test them then look at what replacement parts are needed. Quote Link to comment Share on other sites More sharing options...

Even a full rebuild of every possible part, has got to be cheaper than a replacement injector 👍 How long before you get them back ? Quote Link to comment Share on other sites More sharing options...
Popular Post JonC Posted February 12 Author Popular Post Share Posted February 12 Colchester fuel injection contacted me this morning, all five of the injectors need overhaul. They aren’t spraying - the guy described it as hosing which is basically dribbling out. Also they aren’t putting enough fuel out and I think he said they leaked as well so not good. The cost for each one is £75 plus vat so £450 all up. I was quite pleased with that as it was in the price range I was expecting and the fact that they are U/S should mean that I’ve found the problem which after spending a lot of time messing around eliminating other things will be a relief. I should get them back in a couple of days. jonnyswamp, Dicky, Andy135 and 4 others 7 Quote Link to comment Share on other sites More sharing options...

Excellent result, both spray pattern and volume are critical with injectors, also, over time, hosing can damage the piston crowns. Are they supplying new bolts and seals, or are you getting OEM ?

I’m getting the bolts from Stuart who runs Arvor marine parts, he gets all the various service stuff from a contact at a VW dealership I believe so gets the right stuff. Im assuming the seals 🦭 will come with them, but I will check when they call me to collect them. Quote Link to comment Share on other sites More sharing options...

Are you replacing the leak off (spill) rubber pipes or reusing the originals ? , I think I would stay with the original pipes as the quality of aftermarket pipe is not great. I have a good feeling that this will fix your starting issues. Quote Link to comment Share on other sites More sharing options...

I have a good feeling that this will fix your starting issues. I changed the leak off pipes a year or so ago, I have the replacement ones I put on and also have a bit of new stuff to replace any that look iffy. The new bolts, should I add a bit of copper slip to them or would that affect the torque settings? Talk setting is 25 Nm, I assume that is dry?

Personally, I would leave them dry, just like when they were factory fitted. Also, 25Nm is hand tight and a tweak, unlike my trailer bearing retainers that are 5 grunts and a hernia at 270Nm. copper slip has a habit of drying out when subjected to continual heat, and that could cause the threads to gall, which you really don't want, as that is a whole new world of pain.

JonC Posted February 15 Author Share Posted February 15 Well it’s all back together, I did the injectors up pretty tight but the tork wrench didn’t click It’s not a great quality one as I don’t have a lot of use for such things normally. That said I consider myself fairly strong, I do a manual job so my tight is probably as good as the next guy’s. I fired up, it took a bit of cranking because the system would have been dry. Still a little bit of white smoke but maybe that’s residual shit burning off. I had a blast up and down the river and it’s still hitting the high revs so at least haven’t gone backwards. The telling will be when I go back down tomorrow and try to fire it up. daio web and captin slows old outlaw 2 Quote Link to comment Share on other sites More sharing options...

Yes, it would have been slow to start today as there was air in the fuel system and I guess yours is self bleed, which takes a fair bit of cranking to remove the air and then build the correct fuel rail pressure you should notice better fuel economy, better throttle response, and hopefully much better starting from cold. Yes, 25nm is not a lot, sort of tighten with a socket and then give it just a tad more. I am guessing it is an ali head. Good work 👍 JonC 1 Quote Link to comment Share on other sites More sharing options...

As ever you are right, I couldn’t care less about what the smoke looks like but the fact that it is there says something isn’t right. The starting issue is my number one priority, if the smoke fucks off it’s a bonus. Even if the injectors aren’t the problem it’s not a total waste of time and money as performance should be up and fuel consumption down, so that’s a good thing.

The starting issue is my number one priority, if the smoke fucks off it’s a bonus. If the starting is bad, then you will always get a good dollop of smoke as it burns off the excess fuel. The quicker it starts, the less smoke. On a euro 4 diesel (like yours, about 10 years old or so), then I would expect light grey / blue grey smoke on every start up, that very soon clears. The colder the air temp, then the more the smoke. Looking at those injectors and the way they tested, that is definitely money well spent and TBH you have avoided bigger issues in the future. 👍 daio web 1 Quote Link to comment Share on other sites More sharing options...
