JCW - From Kevins post on page 2...

Quote:
The bung under the oil filter is a new discovery on these engines.
When mine came misplaced it flooded the intake with oil. If the second turbo isn't regularly exercised, oil can pool in the inlet system hence a possible puff off smoke when it is used. Not all cars do this however.

I can summise that it's main role is as you say to allow drain back of oil when changing the filter - but Kevin mentioned when his was missing, it flooded the air intake. Presumably while the engine is running.

Given I'm losing loads of oil since the last service it had (where they most likely dislodged the bung or discarded it for some reason), but no noticeable white smoke, am i right in saying its likely to be going into the air intake and then collecting the second turbo.

When I say a lot of oil... I put 9 ltrs in over a 4 month period after the service, checking and topping up regularly... still am

This may not actually be the reason for the Restricted Performance but it sure doesn't mean the turbo needs replacing like the LR service centre advise... Ash

Hopefully toby1 will come up trumps and you get it fitted and see what happens.

I’d be surprised if it drains to the air intake opposed back to the sump, albeit cannot explain Kevs symptoms or where your oil is disappearing to!

If 9 litres is being passed through the intake over a 4 month period, I’d expect it to smoke constantly.

As always happy to be corrected 👍 Jonathan

I don't disagree Jonathan... maybe because the secondary turbo isn't spooling up (for other reasons) its just collecting there and then dripping out ... maybe.... Ash

Evening. Success. PM your address and I should be able to post it tomorrow as I have to walk into town to the barber. Hopefully I can find something suitable in which to put it.

The hole drains to the breather oil separator which is OK when the engine isn't running but when running the continual flow of oil floods the separator causing oil to be blown out with the air, thereby entering the inlet.

It wasn't my finding, but I couldn't hassle myself to find the original poster.

As I recall, the purpose of this device is to allow oil to drain from the filter housing when the filter element is removed. I think another forum member, maybe jay gee, solved the problem by blanking the hole off with a self tapping screw.

I've just ordered a new cooler so if anybody wants the part out of my old cooler you can have it. Won't be for a few weeks yet though.

Hi Toby,

Just to let you know the clip arrived today - thank you so much.

Ten minutes later, I have removed mine from the filter housing, finding the rubber bung in the process. It was no longer attached to the spring as the top ‘nipple’ had been torn at some point and not long enough and was lacking the little ridge that clipped into the hole on the spring

The replacement is in place and I topped up the oil to get the new level. I’ll drive it around over the next few days and keep a check on it..

Gentlemen - I’m not quite out of the woods yet with the Restricted Performance but I’m pretty confident that you’ve collectively saved me almost £5k on not buying a new turbo…!

I’m eternally grateful to you all.

Thank you Ash

Let's not throw up the bunting just yet, but I am looking forward to developments.

I'm glad it arrived OK. 2012 Vogue TDV8 in Aintree green over sand
