Focus injector

Bpmull

As most know I have a focus mk2 2007 1.6tdci. Anyway there seems to be a slight leak out of the last injector furthest right nearest the fuel filter. It's not leaking where it actually meets the engine it's up on the top and I can't actually see it leaking it's just this one has residue around the top of it where it the wire plugs in where as the rest of them are bone dry. Anyone any ideas would it most likely mean the injector itself is fcuked (hopefully not). Also do I need to take urgent action or what would happen if its left. Thanks.

If it's leaking that far up it's probably the leak off pipe, the small little rubber hose that connects each injector. Maybe it's normal for the DV6 but the three injectors on the right are missing the braiding on their leak off pipes? It might be a sign that they've been replaced or messed with before. New pipes are buttons and worth a try really, it's a 5 minute job. Halfords have them, and any motor factors should have them cheaper too.

Is it wet and does it smell of diesel?

I haven't smelled it. It's just kind of covered in this thick residue it's not like there is diesel dripping from it the bottom of the injector is dry. So it's not really wet it just kind sits on the injector hard to describe. I'll have another look tomorrow. But if you see in the picture the last injector is a did fullerene colour because of whatever it is. Surly if it was diesel it would just run every this residue is too thick but then the only thing that would leak is diesel unless the heat of the engine cause it to dry and leaves the residue.

Yes it doesn't seem to be a fuel leak so. It looks to me like the sealing washer is just starting to leak.

Is that a big expensive job ? Does it look to you like someone has been messing with or changed the injectors ? They look fairly original to me or is there parts missing from the hose? Thanks George.

No it doesn't look to me like there is anything missing or incorrectly fitted.

The washers leaking is a common issue with those engines.

If you catch it early then it is a very easy fix, probably cost about €30 to get it done. If you let it go then you end up with a bigger job on your hands. Nissan Doctor posted a good thread a while back about a pretty bad case of it on a 1.4tdci engine so that might be worth a search.

Ok thanks would that be 30 euro for the part plus labour would you have to recode the injector etc or is it more straightforward than that. By the sounds of it I should get it done sooner rather than later.

George Dalton

The only part needed is a new copper washer, the rest is labour. There is no need for injector coding or anything like that.

Basically the job consists of removing the injector and cleaning off any residue from the area. Then using a special reamer type tool to make sure the injector seating area in the head is perfectly clean, flat and smooth. Finally just refit the injector with a new washer and you should be good to go. 20-30 minutes work once the injector isn't seized into the head, which it won't be if you catch it early before the problem develops too much.

Thanks a million George as usual. I'll try and get it done straight away.

How did you get on BPmull ? I had similar problem with my Peugeot 1.6 Hdi last week smell of burnt diesel coming out from injector 3, went to garage that specialize in repairing Injectors mechanic had quick look & said big complicated Job €250 all in should sort you out. :eek: 4 days before christmas bloody nightmare. I told them id think about it.

On i went to another garage guy had a look he was able to more or less diagnose & fix the problem on the spot (has a lot of experience working with french cars) he took out a socket set & tightened down the hexegon nuts that keep injectors in place, No more engine fumes coming into cabin when i turn on heating So far so good. He didnt charge me anything either. But if problem starts again il get new seals & get all injectors done.

I went to George dalton in the end. He replaced the seal and seems fine now he done a great job. You were right not to bother giving the injector specialised 250 euro. Better to replace the seal first. It's not a huge job to do maybe George just made it look easy he removed the injector replaced the small seal and put it all back together. I'd be doing that. If the engine isn't running rough and just leaking then chances are all it is is the seal. I wouldn't even bother replacing all the seals if the other 3 cylinder injectors aren't leaking. Just do the one if that's the only problem it will only cost a fraction of the 250 euro to put right. Hopefully that's all that's wrong.

I had leaky injectors in my Saab tid replaced 4 x Bosch washers were 5 euro on eBay. Got a guy to replace all 4 washers for 30euro took around an hour or less. fiddly job with alot of cleaning involved. So don't get ripped off

If the reamer for cleaning the bottom of the injector hole is not, err, present in your tool kit, I did one in a pinch on a 2.0 hdi peugeot engine using a forstner bit designed for drilling flat bottomed holes into wood - because it's a wood bit, it removed the crud and left the face flat and intact - popped in a new washer and went to tighten the hold down bolt...which was sheared (van was towed in already played with.and these PSA engines use a rubbish, poor, bad hold down system...) I hadn't noticed as it was sheared off a few mills down in the threaded hole. I migged a blob onto the sheared stud to build it up, and welded on a nut but it wouldn't hold, just kept shearing as well - so I stick welded on a blob and a nut and out it came(stick welding runs hotter and bites better somtimes). Job was oxo. I did another where the hold down bolt had stripped the threads after someone overtightened it in the alloy head - despite dire warnings not to, I drilled out the hole, put in a helicoil and it never budged. Might get someone out of a spot of bother.

Also hoover the crud very thoroughly out before refitting the injector seal - I modded a hoover with a foot of 6mm tube and some duct tape to get down into the hole for the last bits. Chuffing injectors are a pain.. Another bit of an errr.cheat is to weld a blob of MIG wire onto the upper rear face of the hold-down bracket while you have it off the engine- it increases the leverage of the bracket on the injector if the hold-down is a bit marginal(as it often is). Also, a flat nail bar that has had some minor grinding applied to it's business end to make it "injector hold down shaped" plus a suitable bit of aluminium or hard-wood will often shift a stubborn injector if you left your injector puller in the same place as you left your reamer..
