L322 Leak from High Pressure Pump

Hi,

I decided to get my RR service today as it's not been done in a few years (£375) which I did, but they have told me that they discovered the High Pressure Fuel Pump is leaking pretty bad.

The garage then told me that they don't even want to take a guess at how much it would be (mainly in labour) to take it off get it reconditioned and refit. They recommend that I take it to webuyanycar and get rid of it.

I put in the details and they offered about £1k, so when they've inspected everything I expect about £800.

Even if I was offered £1k I've just spent £395 on a service today and £500 on new tyres 6 month ago, plus hundreds on new discs, pads brake pipes etc.

Apart from the being out of pocket, I'm also really fond of the car for some reason, 17 year old but still looks great, runs perfectly and has everything you can think of Inc. digital TV and PlayStation.

Instead of paying the garage £0000's to do the repair, I was thinking of doing it myself over Christmas, by buying a second hand pump and fitting it.

I just wondered what your thoughts are on this? Is it overly complicated? From what I've researched it just looks time consuming and needs a £40 tool. Or would you just take the £1k and cut your loses?

Any advice appreciated

Cheers
Chris

Other members with more experience of the TD6 will have to advise you I'm afraid, you'll have to take into account milage and gearbox service history and don't let your heart rule your decision instead of your head.

Have a watch of this video i would say easier than changing a pump on a p38

Fix it

If it was leaking badly surly you would have seen drips under the motor and smelt it.

Haha I just posted that exact video, but for some reason it's disappeared!

Anyway £17 for the seal kit, £40 for the tool, nowt loose really ‍

I park it on a muddy, gravel surface, I did smell some diesel the other day whilst under the bonnet tbh, which started me thinking about the service

It's unlikely to be the pump on the td6 engine

Hello all,
Quick question. (i did search first but didn't get a lot of useful info. Lot of info on here but not always in a thread with a related title!!!!).
I'm about to change the high pressure fuel pump (injector pump).
Drives great but seems to leak fuel under load (i noticed it first when driving up ramps to do gearbox service,,, dripping off engine sump). Doesn't leak standing or at idle. The general pump area looks like is been leaking with worst area at the back near the pressure sensor. But so hard to get to. So decided to just change pump,,, makes more sense to me. Exchange pump is £160 from Germany,,, and it eliminates me testing etc. Just swap it out. And in my book preventative maintenance is way better than reactive!!!!

In doing so the inlet manifold has to come off as well as coolant drain, fan and cowling out etc.

My question is this:
Is there anything else preventative I should be doing while that area is stripped and coolant is drained?
Like thermostat, particular hoses that fail, etc.

My first L322 (two P38's before). I have some history so will check whats been done in the recent past. Only had the car 3 months so learning all the time. I'm reaching out to seasoned TD6 onwers who know much more than me about this vehicle.
I'm only looking for things at this point that should / could be done (and be easier) at same time.

Any advice very welcome.
Thanks.

Worth changing the glow plugs when your in the area.
Also check the fuel lines and vacuum lines that are buried in the area too.

I would be having a very close look at the hoses going to the HP pump, making sure the ends of the hoses are ok and the worm drive clips are tight.2007 TDV8 VSE

Thanks guys. Useful info.
I've had a peek at the hoses, very difficult to get in there but will try to see if jubilee clips (worm) tight before starting job.
I think you are saying they might be the cause of the leak?
The whole pump does look like its had oil or fuel on it. But so hard to tell and you know how oil spreads in all directions especially if there is a bit of dust or dirt to soak it up.
Thanks.

I had a similar leak and thought the worse so I kept putting it off. When I got round to checking the hoses I found the ends degraded and the clamps not tight. Hoses trimmed, new clamps, a bit of a cleanup and all good. Max 30 mins. I hope you are as lucky. I think if the actual pump leaks you will get diesel fuel in the engine oil so give that a sniff if you are concerned.2007 TDV8 VSE

Wayneg.
Your suggestion paid off.
Hell of a job getting in there and I don't know what type of tool you need for those jubilee clips (but i don't have it,,,, yet).
The hose nr front of engine (feed) wasn't tight. The rear one OK.
The hoses aren't split or leaking, but they need replacing as bit perished on the bends.
Fingers crossed that was it. I'll know soon enough as doing both diff oil changes in next week or so, and every time the car has been on ramps (Engine, gearbox and transfer box services) its leaked diesel.

So thank you very much for that

Good work. Hope it's sorted!

bigpatty, glad to hear you had a result. I recal using a 1/4 drive ratchet with a flex extension to get at the clamps. The rubber had degraded on mine and become soft and swollen at the ends, presumably allowing the clamps to dig in and become loose. I just cut off 10mm from the end and new quality clamps..2007 TDV8 VSE

Not too bad a job to be honest but I'd allow a couple of days works. Have a look here if you're gonna have a go https://www.landyzone.co.uk/land-rover/2005-td6-not-starting.359145/.
And yes you will need the removal tool, I have a brand new unused one as I borrowed one from my local indi before mine arrived but you are a bit far away.

Appreciate the replies, I'll check the links and clips before I take it off. I'll buy the removal tool too, thanks for the offer backinblack, but I'll buy one, don't mind spending £40 if the other option is spending £000's lol

That's the video I followed on a lovely warm summers day
I didn't remove the fan though.

I don't have that luxury, December in Sheffield. So freezing and raining I guess!

Did you have to release the fuel pressure or drain the oil?

No pressure if engine's not going. And no oil there either.
Don't envy you, better get your thermals on.

I did mine about this time last year, not such a bad job, I followed the overhaul instructions posted here but my pump leaked. I then bought a recon pump off the bay and haven't looked back, cost me less than 300 quid from memory. Whilst you have the manifold off worth cleaning the ERG and maybe the manifold as they fill up with soot and you have to take them both off. Getting the fan off is fun, I couldn't do it without, you will need a viscous coupling spanner. Try overhaul first, if it still leaks, replace it you have had all off before and know what you are doing so will only take a morning. Good luck

Will be following your progress with interest, glad you have decided to fix it, no doubt I will be tackling at some point in the future. So much good information on this site and so many fabulous guys n gals willing to help fellow RR owners (or should that be sufferer's lol). Great earlier post from backinblack which I had already bookmarked.
Good luck

@dwarfer did his not long ago not sure if he posted about it though and he`s not in the best of health so give it a go.

Hope everyone had a good Christmas!

Going to order the parts today and get it done early in the New Year. Will take some photos throughout and post on here incase anyone has to do it in future

Cheers

Morning,

Temp got above 0 deg c yesterday so started working in the engine. It's fiddly to say the least, but I have got to the point of removing the pump, in the video above it says use a 17mm bolt to remove the pump cover. That may have been the case when driving out of the showroom but 18years of dirt makes it difficult, I'm therefore waiting for a 17mm hex bit bit be delivered today before I can continue.

One think I did notice is the amount of sludge (carbon build up) in the inlet manifold and ports (see pic) it's about 5mm thick all round.



Whilst I'm waiting for the hex bit I'm going to try and clean these, has anyone got any recommendations for this? Also what's the impact of some sludge falling into the engine? It does scrape off off a screwdriver, but I'm sure some may fall in no matter how hard I try.

Cheers
Chris
