Oh dear - anyone fancy a project?

I'm considering cutting loose of my D3 tdv6 - sadly Sad

Issues have been piling up, and just as I was about to get a clutch job done, I've seen a fluid leak down the back of the engine on the drivers side - I can't see a leaking injector union or leak off hose - so can only assume it's coming from the HPFP.

Cost of doing a clutch, HPFP and lower steering column shaft put me off (I like to do my repairs DIY) - time to think about putting that sort of money elsewhere; I think it's time for her to go to an owner who can sort her out and enjoy her.

I'll stick something in the cars for sale section shortly - had a good 4.5 years, but now time to move on.

It turns out I like a project!

Issues:
1. Clutch slip - 3 piece kit and DMF fitted locally - COP bracket presence verifed both before and after job.

2. Flex section on exhaust downpipe broken - I supplied the clutch fitters with an aftermarket downpipe with cat from BM rads (p/n: WCD500433) - this part supplied from AF (although I didn't buy mine from them): https://www.advancedfactors.co.uk/wcd50043...0227-p.asp

This has had the curious side effect of resolving an exhaust smoke issue I was having - whereby the car produced excess smoke under 'effort' most notably at night time with lights from cars behind me. Oddly though, the turbo noise is more apparent - anyone had any experience with these aftermarket parts being slightly 'louder' than LR equivalents?

3. rear propshaft centre bearing ruined - it was spotted during clutch change. New prop supplied by AF and fitted in an afternoon:

Glad I just went for a new prop, as th UJ at the rear diff end was notchy as well.

4. Oil leak - coming down the offside of the bellhousing. Changed the diesel leak off pipe assembly, using new o-rings - thinking that the moisture was coming from the rear injector area on offside bank - that didn't fix it.

There's moisture in two relevant areas at the top of the engine; first is round what I think is a crankcase breather of some description, on the offside bank:

The second is apparently dripping down off the brake booster pump:

Is it conceivable that there's a diaphagm in that breather that might have torn, and oil is coming out around the breather and dripping down past the brake booster pump?

Alternatively, its quite conceivable that the seal for the pump is leaking, but that wouldn't explain why there's moisture around the breather?

Here's what the leak looks like down the bellhousing:

Has anyone seen leaks from these breathers in the past? I feel like that might be the easiest first start to investigate further?

Other issues to address - clunk in steering/notchiness in steering; replacement lower steering column shaft ready to go on - temporary fix was to soak the UJ on the existing part with fluid film - which has made the steering much more 'fluid', but of course hasn't addressed the clunk.

My gearbox breather was spitting oil out, no idea why but I extended the pipe up to the second battery box and put the end into a small pop bottle
It still collects a bit but now I have no more burning smell or vapour/smoke from the back of the engine

The breather you have shown in the picture actually isn’t one - this is where the vacuum pipe connects on the Jag variant of the engine to operate the flaps in the cam covers for their variant of the emissions control. On the LR variant it is just left unplugged as you have it in the picture. Oil leaking from here may be a symptom of a flap collapsing inside the inlet allowing pressure into the top chamber and allowing a leak out via the open end. Is there any pressure there - this was a symptom on my first D3 when the flap went.

That's interesting - thanks for the insight. The moitsure is around the 'top hat' piece of the breather as it clips on to the rest of the intake manifold, rather than the small connection for vacuum hose that's not connected to anything; if that helps?

I'm tempted to pop the top hat off the intake manifold and inspect, but not sure what I'll find and/or whether I'd be able to put it back on to the intake manifold - i.e I don't want to cause myself a massive headache by investigating something I'm unclear on!

What happened in your case?

EDIT: Just found this product on the web:

I wonder if the issue I've got is a tear in the diaphragm part... might well pop it open and take a look, although I am now slightly nervous about the prospect of part of an unsed swirl flap breaking and getting ingested by the engine - I'm not sure I've ever seen that reported for a tdv6 in a Disco though?

That's an interesting thought as well - not sure why this would start to be the case on my car, when not an issue in the past. Last changed the oil the transmission two years ago and was careful to fill to the correct level.. confusing...

before you affected your solution - was yours spitting enough oil such that it was leaking down the bell housing?

Hi if you take a look at the picture above, this is the underside of the Inlet manifold assembly that the vacuum diaphragm is on the top side (away from the camera) in my case the lower of the flaps in this picture had collapsed and been eaten by the combustion chamber. I'm sure if you take a look down the inlet connector by taking off the throttle body with a USB probe camera you could see if anything was amiss inside the actual inlet cavity (the wireless endoscopes are really cheap on Amazon and would do the job for around £20)

eek - so a piece of the flap had come apart in your case, and got ingested by the engine?

I daren't ask, but what was the damage?

No damage from what we could see Compression was good and all readings were fine after the repair - ironically the only reason it was spotted was the car wouldn't go up hills in North Yorkshire National Park without going into limp mode (first day of a weeks holiday) the cause of the limp mode inducing fault appeared to be this, but after replacing the inlet (with one from Ebay from a seller 6 miles away), in a car park in the rain the problem persisted. (8 hours in the pouring Yorkshire rain with just hand tools from a nearby Halfords)

It later turned out to be corrosion on the turbo actuator that had caused the problem - it was resolved by using a Barbeque skewer to work the actuator whilst dosing it with WD40 - 20 minutes work with bits from Asda Supermarket

However the car continued to run smoothly for a further year before spinning a bearing, which I dont think was related as thats a common issue

Interesting - but how did you actually spot a part of the flap was missing? I do have a boroscope, but I prefer the idea of popping the top hat off the intake whilst it's in situ - looking for a tear in that diaphragm- hopefully.

The reason I spotted there was a problem was all of the crud built up around the area of the vacuum connector nozzle and that there was pressure there if you held your finger over it. I first thought there was a pipe missing so did some searching here and realised there shouldnt be a pipe or any air blowing from the nozzle.

Most of the crud was built up on the bracket at the rear that is in your picture.

Didnt take the top hat off as I took the throttle body off and went from there

What I do not understand here... these flaps or valves are permanently open if there is no vacuum applied as far as I can see on my engine... so a broken or lost valve should make no difference regarding “pressure” in any chamber, since everything stays the same

Open valve or no valve..

quick update; the turbo noise turned out to be a couople of nuts on the flange for the turbo to the downpipe being slightly loose - all done up and she's quiet and smoke free.

Next issue to tackle is the oil leak down the bellhousing. I'm going to try the tip of extending the gearbox and transfer case breathers in to bottles, and see if I get any spitting first.
