Congrats on your new toy.
Just to add my 2 cents. I would recommend keeping it stock, it was engineered in this fashion and it will work extremely well if you do your part.
1) This is an English built vehicle, so maintenance is a big MUST!
2) Get manuals
3) Get in a LR Club
4) get some good tools and lots of bandages
5) get a good wire stripper and crimp and lots of connectors and wire
For maint.
1) go for electronic igntion, the pertronic Ignition is very good and requires no mods.
2) Always check your oils (engine, gearbox transfer, diffs)
3) Change your oils and filters at regular intervals
4) Clean oil bath filter and fuel filter
5) adjuts tappets every 6 months (easy to do)
6) If non electronic ignition (change points, pickup and ballast)
7) learn to tune the engine(lots of good material on the net for this)
8) adjust brakes
9) grease everything that has a nipple on it (excluding wife or GF)
10) Tackle loose or worn wiring asap and do it properly
You will always see oil leaks, this is an LR feature. In reality its a oil capacity gauge, when oil leaks do not appear, it means you have no oil in something
Rust and LR have a fond attraction for each other, when working on LRs always be prepared to tackle the rusted bolt that broke, this will usually be the one that is least accessable.
another thing is if the LR is one with two fuses , install a battery quick disconnect. If driving and everything starts to flash as if possessed by the Princess of Darkness, something is shorting and most likely its not on a fused cicuit
They have character and will grow on you.
I would also do a good chassis cleanup and check for rust spots. Get those fixed right away. A good welder will do wonders. Most likely area rear X member, and front horns. On the body check door pillars, foot wells.
Hope this helps
