So, work intervened again! First, a short summary:
The oil cool leak turned out to be no big deal, except for some ugly stains in the drive wway which are luckily hidden from my wife for most of the time. JLR did a good job, not even too expensive. Replaced one real axle seal, the tank, did a complete oil change (axles, gear box, transfer box, engine) and a general service. Even replaced the front propshaft with a after-market one I had ordered before. nad the tank is not original neither.
Had some time to check the electrics. Did I mention already that the wiring is a nightmare? Well, now the horn is working, as is the rest of the AUX circuit. With the exception of the wind screen water pump... At least the fuse isn't blowing anymore when I try it.
Next steps will be a secondary battery, for stuff like a small fridge, some reading lights, external lights and so on for camping. and the interior, carpets, sound deadening and the headlining. he latter will be made out of wood, with some added storage in the back. Front seats will go to the local shop this week or next week, one by one. After that, front and rear shocks, and she's all done! Except for tyres, and maybe a engine revision one day!
Hope you are all doing well during these crazy times!
