Are you sure the leak is not the pipe at the rear of the oil cooler? That’s a common place to leak.

Yes, the turbo oil feed is all dry. I think previously the rings were changed. Because I can see that someone undid the oil cooler gaskets from unmatched bolts which are on now. 2011 Vogue SE 4.4 TDV8

Hi all, came across this forum whilst trying to research/locate an oil leak on my 2013 4.4 sdv8.i had the oil cooler gasket replaced back in December 2021 and all was well until about 6 months when an oil leak was noticed on a service. I got what seams to be an intermittent oil leak towards the front of the engine somewhere between the throttle body and drivers side valve cover, it can go days with no leak, then a slight leak and then lots dripping from everywhere under the drivers side of the engine, when it leaks it's also spray oil up onto the engine cover (lots of oil it's soaked) and the bonnet when cover removed. I've check all inlet pipes, egr, valve cover and anything else that can be tightened and tried looking for it whilst putting the car through different rev ranges but can't locate it. Not sure if it's related but when driving if I drive hard enough for the secondary turbo to kick in it blows a puff of blue smoke, but once the smoke has cleared i can continue to drive hard and no smoke. I don't think the oil leak is a turbo seal as the amount it's losing I'm sure the tailpipes would be constantly pumping out blue smoke so wondering if anyone has experienced this and have any ideas what's going on as I'm completely stumped now.

After 2000 km trip, I have a lot of oil on the engine cover where the throttle body is. Before the trip I put 3 o-rings on the air inlet connection to the throttle body, as described on this forum.
It looks like oil was squirting around as it has reached innner side of the bonnet.

Is there anything else in this area which can spray oil all over the place?`

On the weekend I will undo the air intakes and have a better look. 2011 Vogue SE 4.4 TDV8

Hi all, I checked mine this morning after noticing oil on the bottom of the undertray - no smell or dripping but is obvious if you look around the engine.

The oil cooler was replaced 6k miles ago but I'm not sure if the o-rings where done at the time, it looks a bit sticky - would you suggest replacing them? Cheers!

Hi all,

I recently changed oil by draining from the pipe on the oil pan. I am pretty sure I pushed in that quick connector as much as I could but It is very slowly leaking.

I guess there is o-ring in the quick connector which I could maybe replace? Does anyone know the size or a partnr for it?

thank you all 2011 Vogue SE 4.4 TDV8

How have people managed to tighten the 14mm bung on top of the oil cooler?

This one to be exact -

is it this one shown below - go to nino nino post 28th May 2019 for more info

the nut in my photo below is just in the way of unscrewing the plug on top of the oil pump

I've managed to get to it, but I can't get a 30CM allen key that far down, and I'm not sure a socket will fit?

Cheers!

Hi all, I had a coolant leak on my 4.4TDV8 which I located to the drivers side of the oil cooler….

So with the help of this post and LRtime video I have just replaced the cooler.

Now with it back together (not fully thankfully) I have confirmed that the seal in the angled coolant connector has worn and can’t hold pressure.

Does anyone know what size this is please? OD of the spout on cooler is 17.5mm width of old seal 4mm but it is flattened.

Well, decided to do my o rings yesterday as I had the oily smell. Managed to overtighten the securing bolt and snapped it off so a new oil cooler has been ordered.
Not the end of the world, but a pain in the arse; on a positive note, it looks like the oil cooler seal was shot so I would have had to do it anyway.

Well managed to get it done before the weather set in. With the excellent thread over in the wiki, it wasn’t too bad a job. Managed to butcher an electrical connector but otherwise reasonably straightforward and if there were a next time, I’d probably be able to do it an afternoon.

Top tip-get a magnetic 8mm and 10mm socket, or use blu tack.
