Does any one now the purpose for the rear sump bolt as the cross member is in the way for draining.

The 4.4 tdV8 was specifically designed as a “top down maintenance car” ,
Forget draining the sump from the bottom and use the suction tube from the top.
It is so much easier, cleaner and quicker.

I understand that Mike but as land rover call it "mini sump" I would like to know its purpose as there's a main drain on the side and this which I questioned too.

Also having a ramp of my own I prefer to drain properly/fully rather than a suction pipe, don't get me wrong they have designed it that way but my preference is gravity will always win.

I appreciate your preference Pete..
I was never a fan of sucking oil out, but having seen how much I get out and reports from Nino whose opinion I respect greatly.
He sucked his out then went further and removed the 2 sump plugs but only got out an extra couple of spoonfuls, so, each to his own.
Cheers

It’s a drain for turbo pipe I think. Drain it when you drop the oil from main drain. Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Thank you Rob I'll see how much comes out on the next oil change.

I have to admit to being a convert to sucking the oil out too now.

Having said that, I still open up the rear sump plug to make sure I get all the old oil out.

As previously mentioned it's a drain for the turbo return , drain it at every oil change as it can eventually sludge up and cause turbo oil starvation (very expensive ) as the hot oil can't return to sump , same for 3.6's too , I suck the main sump dry with suction pump then drain the turbo return (a bit messy as it dribbles onto crossmember ) , standard Ford type sump plug and o ring seal , only a couple of quid so replace with a new one .

I have been monitoring the oil dilution rate since I downloaded the latest iid software.
It’s gone from 0 to 0.8 in the 2k miles I have managed between lockdowns , but given that 7 is quoted as the max level and the fact I change it twice a year under normal driving use, the small amount left in compared to the 8.5 litres of clean new oil flowing through a new filter element each time can’t possibly be much of a problem.
