I have a 2010 Vogue 4.4 tdv8 Range Rover Vogue SE and just sorted an oil leak out and would like to share the Fix .
The cooler has 2 gaskets an upper and lower and also 2 x o'rings on a pipe leaving the oil cooler at the rear for a pipe to the turbo I believe.
I've found the part numbers of the gaskets and o'rings.
O'rings I have found are not a Landover part but what I can see possibly better but made of the heat resistant material (Viton) 9.00mm x 2mm c/sec 141455807170 sealssuppliesuk. The risk is yours , I cant advise . for obvious reasons .
Base plate gasket LR077242
Upper gasket to cooler LR 022903
£2.87 for pack of 10.
Worked great but a little tight pushing in . Using the bolt and an alternating wiggle working with a n 8mm ratchet worked fine .
I ordered all the gaskets because the job to replace then isn't quick and I found other jobs need rectifying on the way .
Like all that plastic parts on the cooling just break .not good on a car of this price and quality.

I ordered all the gaskets as previously I read that only 2 areas leak oil but i found 3 .
2 gaskets and the 2 o'rings see the pics.
When stripped the whole area is covered in oil so hard to locate the source of the problem . And it's not as if you can clean it down and start it up and monitor as the intake manifold is removed . And to refit and remove again is a bit of a task .
In total it took with cleaning all the parts . ( Intake cleaning isn't a great job) a day without rushing . Bear in mind of the plastic parts just crumbleing and needing repair. All jet washed off and now seems to be fine .
The radiator coupling has a repair kit from Landover but I've deleted the cheap plastic items as I go through the job .
Any questions I'm happy to help

Hi,

Thanks for this, going through the exact same problem.

I have broken the 4 way water house coupler as with you picture. Where did you get this metal coupler from?

Thanks

Nice job!
I did this a few month ago. Unfortunately I didn't find this post earlier.

Just so disappointing the amount of plastic (often of inferior quality) being used in cars nowadays. Although it seems BMW is particularly affected by their choice of plastics. I had a beemer and in the end had changed out the whole cooling system. The same strange layered brown effect on the plastics like shown in the pics.

I have a few older cars and the few plastics fittings on those (~1980) seem to be just fine so plastic can last if you use the correct materials.

Just done an oil cooler on a 4.4tdv8, I found the 9x2 mm o rings too big and very hard to connect the pipe to the cooler
The actual o ring part is
BS012 1.78mm Section 9.25mm Bore NITRILE 70 Rubber O-Rings
this fitted perfect
