Also, it might be worth re-checking sump bolt tourqe after a couple of days. Did mine today before putting under tray back on and was surprised how much they tightened up, despite already having done them up to 25nm as per manual.

As I have now decided to go ahead and do this, in my research on it, I found a note from LR modfying the the torque setting on 4 of the bolts to 28 ft lbs.
I'll find it again and put the post up.
td5 sump gasket modifed installation practice

A new specification sump gasket has been introduced to improve the seal between
the sump and the engine block.
With the introduction of the new gasket
there is a requirement to increase the
torque applied to bolts 11, 14, 15 and 18 in
the tightening sequence (see illustration 1).
The bolts MUST now be tightened to 28 Nm;
the remaining sump bolts MUST be
tightened to the original torque of 25 Nm.
The removal, installation, tightening and
sealing procedure remains the same as per
the Workshop Manual.
