cant really hear that well but sounds like a 2.5na thats running slightly slow, but sounds ok other than that. If its sat around for a while then will need a googd run and some TLC to get it smooth, mine took about a month or so of lots of fiddling/TLC and a couple of good long runs to get it smoother/less smoky etc.
Also if you are just starting it on your drive and letting it idle, thats fine, but let it run for a while not just 5 mins, you need to let it get up to operating temp then let it sit idling for a while once at temp.
Ideally you need to drive it around
I would if i was you i would do the following unless you have already done it. You could get a garage to do it but you have the ideal vehicle to learn spannering on IMO
1. change engine oil and filter
2. change fuel filter and clean out fuel sedimenter in the rear drivers wheel arch
3. drain out the coolant and fill with new on 50/50 coolant/water or 70/30 mix depending on how cold it gets where you are
4. change the gearbox and transfer box oils.
5. change the diff oils front and rear
6. change the timing belt and idler and the alternator belt
7. grease your propshafts and check/change the swivel oils
8. check your chassis very carefully to make sure it doesnt need welding anywhere.
9. check wheel bearings and re-grease if needed.
10. reset tappets.
11. check disc/pads etc for wear/pitting/rusting and change the fluid/bleed the brakes if the pedal is at all squishy or vague or the brakes lack 'bite'
That sounds like a lot but you dont have to do it in one go, you can do it bit by bit as and when you have time and money, some jobs like the timing belt you may want to get a garage to do till your more experienced spannering. Get yourself and haynes manual which will guide you through it, and search and ask on here for help with stuff!
