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
