I made the same assumption the first time I topped up the P38 auto box. With the t-case I’m not sure it’s even possible to over fill as you normally top it until it runs out the same hole as you fill it with. I just threw that in in case it’s actually possible to add fluid through a higher location.
And I suppose it’s almost impossible that it could be over filled?
Glad to hear you got it sorted. And for free!
I would also endorse the RSW software. I had RSW before I had the Nanocom. The Nano is easier to use, but so far (I think over 6 years) RSW would have taken care of everything I’ve needed. I bought the Nano after I added the Disco to my fleet.
If it was me I’d probably try a bit of judicious application of the park brake while driving to try to “burn off” the residual oil. If you try this be very careful as you could easily cause more harm than good.
Pierre, thanks for the detailed description of how you did it. I may (or may not) need to do the same one day.
Happy to hear that you found the problem.
Good news about the shifting! Maybe it’s something we all need to look at on our 25 year old vehicles.
I understand what you’re saying (I had a Dodge Dakota that I deleted the cats from, so I can’t be too judgemental about this). In the case of the PCV system, I don’t think there’s any good reason to delete it.
And to be fair to the “normal workshop”, troubleshooting can eat up a lot of man hours. Most customers don’t want to pay hundreds of dollars/pounds to figure out their issue.
Thanks for the thorough explanation Richard.
Are you talking about the Positive Crankcase Ventilation System? I don’t think there’s a good reason to delete it.

Does this help?
03 & 04 were all 4.6 IIRC.
It seems to me that even the slipping liner issue is more of an issue on the D2’s than P38’s. I don’t read much about them on the RR forums, but it seems to happen on the D2 forums I read. The story is that the P38’s got the best blocks every time while some of the D2’s ended up with less perfect ones.
As Pete indicated, the blocks don’t become porous. Apparently the last few years that LR made them they didn’t take as much care as they did during most of the years that they built them.
Also I think that virtually all the porous blocks were made into beer cans long ago.
I think the porous blocks were more of a thing on the ‘03 & ‘04 Disco 2’s. I don’t think P38’s really ever had this issue.
I’m not up on what you had apart. As Richard notes above, the O2 sensor might be duff or it might be telling you the truth. If it’s telling the truth it could be caused by various things. Seeing both sensors (I’m presuming it’s the upstream sensors) are giving you a fault it isn’t likely to be a bad injector. You could have an intake leak somewhere downstream of the MAF sensor that affects both banks.
I think 13.8 is in the correct range for an alternator.
