Leaking Injector now!!
#1
Well Im back again for some more help...after sorting out the Glow plug issue I went out for a run after the engine cooled down just to see if the smoke issue had decreased...it has a bit...then the van started to miss a little..only slightly but I still pulled over and took a look in the engine...I found that there was fuel round the injector (gearbox end...not sure if its 4 or 1 ?)...the same one as the glow plug trouble..Im not sure if its coming from the braided pipes and running down..or coming from the engine...Ive tried to read a post about it but the post went off at a tangent and got me confused...apparently "Polar" has written a post about this issue but I cant find it..plus it may not be relevant to my engine (1.9 DW8 W Reg)...looks like Im going to be busy again...any help as always is greatly appreciated...I think its mapped out that I rebuild this van Rolleyes

Replace the spill hoses (braided hose)
Do them all as they all perish at the ends. Pull it off and you will see the rubber has cracked. As a temp fix (and if hose is long enough) cut off 10mm from each end and refit.

This will be a new van by the time you have finished

Thanks Col...I think I may aswell move down south..it where most of my help is coming from...I think there is enough to trim the one that has a leak..could it be air thats getting in to make it run a little lumpy or fuel starvation...or a bit of both as it would with petrol...the Wife has just asked if its a rebuild project or am I just finding faults to keep busy....if only eh??...Ive plenty to keep me busy...thank you.

You shouldn't get air in through the spill hose. You may have poor spray pattern, or hosing from an injector. If you take them to a diesel specialist, they can test them quite cheaply. I would do it for you, but as you say, I'm daahn saff

The write up i did was for the 1.6hdi they are known for injectors chuffing the 1.9 you have are screw in injectors and generally dont suffer from that problem.

Well chaps Ive changed the hoses and the little blanking cap...cleaned around the injector and the injector body...refitted everything then pushed the hand primer a few times ( not sure if this was needed)..then tried to start up...it took a few turns of the key then it fired up...I checked the hoses...no leaks at all and engine running nice and smooth....no smoke....well maybe a little...then the engine started to miss a little...I blipped the throttle and it started to smoke again...I checked the hoses..all bone dry...but the base of the injector where it goes into the block had fuel round it..I think its run down from the top of the injector (not the supply rail) where the next nut is...I have not tried to tighten it as I dont have a spanner to fit the large nut yet ...I soon will have...and deep socket to match ?....what I didnt do was look to see if any bubbles were coming from the base of the injector...if thats possible...Im going to clean it as best I can without taking everything apart again and watch where the fuel is coming from and see if bubbles appear...having no knowledge at all regarding injectors Im taking things slowly....only because they cost a small fortune...but on the bright side of things...Im learning something new...and Old Smokie isnt so smokie anymore..it will be a brand new van with a "W" plate on it... ha ha
Regards,
Steve...

You need a 17mm spanner for the injector pipe nut, and a special socket for the injector itself. If you are saying fuel is leaking from the body of the injector, then it needs overhauling by a diesel specialist. If that is the case, then you might as well get all 4 done.

Thanks Col..I left it alone for a few hours then went to have another look to see if the fuel at the base of the injector..where it goes into the engine..had drained back down..it hadnt...I managed to get a bit of kitchen roll to it and soaked up what was there and wiped the thing down as best I could, then started the engine and watched...it ran a bit lumpy at first then settled down if I put some revs on...there is a rim/ridge part way down the injector...fuel started to sit in it after a min or so..then filled up the base of the injector where it goes into the engine....so now Im thinking that its leaking from the fuel rail pipe nut...Ive done some reading about this problem and most folk say its an "O" ring that could have worn...I have never touched this rail at all..nor noticed the leak before as I was always cleaning gunge away after doing various jobs...would this sound about right to you...I have forgotten the type of injector thats fitted...I did see a pict of it during my research...will try to find it again,
Regards,
Steve..

    .....Its the Bosch Injectors that are fitted and Ive just remembered that the fuel rail nut is a little rounded on the shoulders..as If the wrong size spanner has been used...or maybe overtightened....,Steve

It's not a fuel rail (common rail) as it has a mechanical pump. The HDI's have a fuel rail and I think you are confusing the 2. Don't try and fix the injector yourself (unless it is a loose pipe nut) The tiniest bit of dirt can fubar it completely.
They also need to be shimmed correctly so the "break" pressure is correct and spray pattern needs checking- All specialist stuff really.
