Transfer box - oil drips from bolt heads

I have drips of oil on the transfer box case bolts across the rear bottom edge. The main auto box is dry as is the cross member. The torque converter was changed along with a refurb of the gearbox in October & it’s done less than 1k since.
I cannot see a leak - it’s golden in colour & clean - looks like the oil I topped up the transfer box with back in the summer.
D3 8A Vin
Any one got any ideas of where it could be coming from? Where does the breather pipe fit? Could it have been over filled?
Thanks

Last time I had a leak from the transfer box it was the seal between the two halves of the box.
If yours is the same it isn’t a gasket but a sealant that is used and the box needs to come out and be split to reseal.

Thanks - hope it’s not but I will clean it as good as I can & see if I can then find out where it’s coming from over the next couple of weeks

Oddly had this when I bought my D3 V8. (LR picked it up in a health check when they did the plugs).

I decided to change all the oils including the TB. A year on its dry as a bone.(Possible overfill previously?)

Yes I do wonder if the TB was drained & refilled during the gearbox/torque converter job.
I am going to clean it & then check the level & compare a sample of the oil with the stuff I got to top it up when I serviced it in the summer.
Will contact the guy who did it next week & see what’s his thoughts are.

I put a copper washer under each bolt head having removed them one at a time & re torqued. No longer have the D3 so don’t know if it’s still dry but it did cure it
