Leaking injector - rocker8742 - 03-10-2014
Got an injector leaking on a 1.9 nad what'd it likely to be the injector or the seal?
How hard are they to change ?
RE: Leaking injector - mr_fish - 03-10-2014
Could be the union on the top, body of the injector or the copper seal.
Got a picture?
I'd probably say it the body, take it out, clamp put in the vice 27mm(?) spanner and nip it up. I've had it before. Fresh fire seal & copper seal and drash on.

Will get a picture in a bit but looks like its covered from fairly near the top
How much of a pain are they to get off and what size?
RE: Leaking injector - ConorTRG - 03-10-2014
Possibly the leak of pipe, they'll make a mess with only the smallest hole, there also a 5 minute job to replace, worth checking the easy bits first.
RE: Leaking injector - mr_fish - 03-10-2014
have you got the alloy inlet? have to remove that and get at them.
You'll need an injector socket I don't remember the size, sorry. Got in my head its 27mm but dont quote me on that.
Edit: ConorTRG has a good point.
RE: Leaking injector - Paul_13 - 03-10-2014
27mm for injectors
Leaking injector - rocker8742 - 03-10-2014
Inlets plastic I think, gonna have to find me an injector socket
RE: Leaking injector - Piggy - 03-10-2014
Worth checking leak offs first mind as said. Diesel leaks can go everywhere from the tiniest hole
And those sockets are about £5/6 on ebay
Leaking injector - rocker8742 - 03-10-2014
Best way of checking them?
RE: Leaking injector - Piggy - 03-10-2014
I would clean off the area with some brake cleaner or similar. Run the engine and watch!
That or clean it off and replace the leak off for 50p and see if it stops it!
Leaking injector - rocker8742 - 03-10-2014
Right had a look at it and its not the leak off pipe looks to be coming out of the injector where the line joins it

The nuts tight, is there a seal inside there that needs replacing?
RE: Leaking injector - Piggy - 03-10-2014
Worth undoing that nut and lifting the line to see what the sealing surfaces are like
RE: Leaking injector - Tom - 03-10-2014
Yeah looks wet above that union!
Leaking injector - rocker8742 - 03-10-2014
Won't be able to whip that off until the morning....
Do you know if there's a seal under that part that I could replace ? Never had a diesel injector off
RE: Leaking injector - Piggy - 03-10-2014
Nope. Its like a brake pipe flange, a male on the pipe and a female on the injector.
Possible not seated right or bent or something
Not been off recently...odd for it to just start to leak there
Leaking injector - rocker8742 - 03-10-2014
Don't know why it's started I haven't touched them since I've had the car not even been near them
Is it possible undoing and reseating it could stop it leaking?
RE: Leaking injector - Piggy - 03-10-2014
Possible
Leaking injector - rocker8742 - 04-10-2014
If not how easy are the lines to get hold of?
Leaking injector - rocker8742 - 04-10-2014
Took it off and re seated it it now leaks more and wont run
RE: Leaking injector - Ruan - 04-10-2014
I'm going to put my bets on leakoff lines - those ones will be seriously hard and brittle.
You'll have just aired up the system, pump the primer bulb, turn over the engine until fuel squirts out the union, tighten up and start...
Leaking injector - rocker8742 - 04-10-2014
All the pipes seem alright Ruan theres no fuel leaking from them (assuming these are the rubber lines between injectors) its actually forcing diesel up through the top of the union
Got a picture of the surfaces and to me they look alright
![[Image: zygezezu.jpg]](http://img.tapatalk.com/d/14/10/04/zygezezu.jpg)
Maybe the injector can't pass the fuel through?
RE: Leaking injector - Piggy - 04-10-2014
Cant see much in the blurr to be honest, whats the surface on the line like?

They should be a bit clearer
The line feels smooth all round

Video of what it's doing looks like line or injector to me, there isn't supposed to be a seal in the union is there?
RE: Leaking injector - Paul_13 - 05-10-2014
There's not a tiny crack above that flare ?

Yeah I would say, in that second pic!

Good spot guys had the line off today to get a proper look at it

RE: Leaking injector - jack_o - 09-10-2014
Nasty. Imagine these would fit but you might be able to get cheaper on the forum.
RE: Leaking injector - mr_fish - 09-10-2014
yeah, that'll do it.
I got a set tom you can choose which one you need.
RE: Leaking injector - 306Dan - 09-10-2014
I've also got a full set + a spare nad anyways, your welcome to them for postage if all else fails
Leaking injector - rocker8742 - 09-10-2014
Picked up the set from mr fish tonight so will get it fitted and hopefully that'll be the end of it
