Unless I can get some dex ii at a lower price, it turns out my cheapest option is filling it with LHM even though it's all gonna leak out while testing - The other options (the flushing liquid, miners oil) are cheaper until you count shipping - shipping any kind of oil or fluid from the continent requires a courier, instead of the post, and getting shipping from the UK without getting shafted by customs is also tricky.

On joining the lines - has anyone any experience with the cutter-style flare-less joints (NOT plumbing-style compression joints)? I've seen the style used on older machines at work (the newer machines use thicker (20mm+) threaded pipes, or hoses, nothing new uses the thin lines anymore) - the type that has a steel ferule that is bevelled in such a way that it crushes/cuts into the pipe in such a way that the only way to get it off is to cut the pipe. I don't know the ratings, but they saw 100 bar at least when in use. The machines they're on shake a fair bit, so I'd say they're pretty vibration resistant, too.
And onto something that will be an issue in a year or two (or three) - after the car's running and driving - is paperwork. I live in Ireland, I am 21. No insurer here would even quote me (too young for a classic policy, car's too old for a normal policy) and I don't really want to go through "importing" and registering it here (RoI) unless it's the only option. Insurance here is ridicolously over-priced - without me getting into a rant, It would be roughly the same price to register the car in Poland (my home country), tax, MOT, and insure it there (that is counting a special policy that gives unlimited abroad insurance for the whole year) - and it's be comprehensive instead of 3rd party, and no mileage cap. The prices in ireland do come down once I'll be 25, but that's years of not being to insure the damn thing.
Another thing - the climate controls currently are not working, no blower motor, no actuator noises. I'd like to just get heat out of it - winter is coming and I'd like to be able to dry the inside somewhat. I'm guessing it's an electrical issue - any suggestions on where I should dig in to?
