Thread: 2016 L494 SDV8 HSE Oil Leak

For under twenty bucks, you can buy a drip tray.

Replace the o-rings with Viton BS611 - 2 of.

I understand that access to the pipe fitting is reasonable once the panel under the wipers is removed, but I only have experience with the L322 where removal of the cabin air intake (remove 2 nuts) is all that is necessary.

The oil cooler gaskets may not be far behind the o-rings in leaking but that's a bigger task.

Nice colour....

Thanks for the reply Graeme, I will have to take a deeper look at what needs to be removed replaced.
Does anyone believe the oil cooler replacement cost of $6k is excessive or is that in the right ball park ??

LR don't list the o-rings as spare parts, only the whole feed pipe that supplies both turbos which takes quite a lot of work to replace. Perhaps the workshop has quoted to replace that pipe and possibly the oil cooler too.

Is there another workshop that will replace just the o-rings if you source them yourself? Any bearing outlet would be able to get Viton BS611 and you can most likely buy them online from ebay or a bearing/seal outlet. Standard o-rings won't survive the heat as nearly as well as Viton (Viton 75 is the common compound for high tempertures).

Just for the record... JC recommends the replacement of the whole cooler.. which I didnt do the first time,, then had to do the second...
There is a bit in the V that requires replacing after 8 years...
personally, if you plan on keeping it forever,, I'd be getting the rad inspected and replacing all the hoses, the small ones especially..

My cooling system concern was with all the plastic fittings in the V, some of which were found to be very brittle during replacement after 12 years even though the engine cover hadn't been fitted since 18K kms.

As previously mentioned but worth repeating...
The SDV8 rad has very fine tubes,and after 8 years of LR servicing they block up... or at least mine did.
After trying to look through it I have no idea how mine lasted as long as it did....
