3.2 petrol brake vacuum pump - oil leak?

Hi all. I know, 3.2 petrol question on a 99% diesel forum but nothing ventured...

I've got an oil leak 'somwhere' around the left hand side (UK passenger) of my engine bay. It's enough to cause a drip from the left hand chassis leg. Oil is also being thrown around when it drops down onto the inner CV joint on that side. Looking further up the engine bay, the highest witness mark of oil is on the outside of the brake vacuum pump. I've snugged all the bolts up and they seem OK. It looks like the leak is here and it's pooling/running onto the area around the gearbox filler before dropping down further.
Has anyone had this? Is it just a gasket I need to change or does the pump need overhauling internally??
The brakes feel fine and haven't done anything strange/scary yet. This has likely been leaking for as long as we've had the car, just over a year, if not longer. Any ideas? Ta.

Fear not diesel owners Very Happy it appears there's a kinda known issue with the pump thingy and there's a seal kit to remedy it.

Here is a good video that shows what needs to be done



The Volvo kit is expensive but it has both O-ring, the check valve and new bolts

Volvo part number 31401556

Note: I haven’t done this yet

Good luck

Paul

Aye thanks, I've seen a couple of YouTube vids from Volvo owners. Doesn't look a particularly tricky job. I'll call around for prices as I've just changed the oil and don't want to be losing too much of it!

At last, a stunningly easy job to carry out! Unlike on the Volvo, I didn't even need to remove the battery. Here's to keeping the engine oil in the actual engine.

That’s great news

I haven’t rebuilt mine yet but it on my list

Did you replace both O-rings and the check valve?

Or

Only the O-ring between the pump and the head?

Take care

Paul

I replaced EVERYTHING that came in the box; both O-rings, the check valve and I even used the new bolts. Such a quick and easy job.

Mr. Paterson,

I just wanted to reply to this Thread because I recently bought a 2010 S80 3.2 and it needed the vacuum pump repaired.

As you correctly pointed out - not a difficult job

Item #10 on the list is done on the S80 (I will need to do it at some point on my LR2)

10. O-Rings for Vacuum pump (~10 years or sooner if the leak is large)

Take care

Paul

Done it .
See topic:

3.2 vacuum pump seal kit 31401556

Not hard. Found taking out battery tray made removal and refitting easier.

Real Beal Thumbs Up

Take a look at this thread

http://www.freel2.com/forum/topic32504.html

Let me know if I should add additional items


The vacuum pump o-rings seem to be unpredictable with the failure

My 2008 LR2 3.2 114,000 miles has the original o-rings
My 2010 S80 3.2 124,000 miles leaked terribly and made a huge mess

I just bought the S80 so I’m not sure when the O-rings failed, if I owned the S80 since new I would have replaced the O-rings much sooner.

How many miles did you get on the original O-rings.

Happy Motoring

Paul

Paul, I don't really know how many miles before they failed as the engine was a brand new LR fitted motor at 114000. As such I don't know whether the engine was a new full engine with ancillaries or was a new engine less ancillaries that were transferred from the dead engine. Also I don't know how long they've been leaking for . I've had the Freelander for just over 2 years now and noticed the leak last year. I cleaned it up and it took a while to return. I decided to sort it but couldn't find a kit anywhere until recently and sorted it as soon as I got a full dry day off.
As for the list. I think you've got it pretty much covered. Wink
