    This is very typical of the PCV plumbing. Inside that valve is a diaphragm which gets sucked shut by vacuum when you close the throttle, it's normal to see though it like that so it's probably ok. The flame trap is a little ball of wire that is supposed to be jammed in the pipe below that valve , my car either never had one or it fell out into the crankcase, I left it out.

    You see in the pic of the pipe with the T you have a place where 2 rubber pipes of different sizes join? There's a one-way valve that lives there which needs to be working correctly

            I have Samco Boost and water kits and I made a metal T piece to replace the other (expensive ) hose that is below the black valve and Ts up to the back of the head.

            I later ditched the PCV system (and carbon canister) altogether and fitted a catch tank as I was running a lot more boost and didn't want to send oil vapour back into the inlet in case of detonation..

                  My aux rad (small rad) has gone, easier for jobs like timing etc. but also gives better air flow to the engine. I can cruise on motorways and the temp will go half way between first line and 90 so it does cool the car down nicely.

                  Air con shouldn't cost you to remove. Just trace all parts and get that pulley out. Lose some weight and sell the parts to an owner who needs it like in Australia or states

                    Small rad out, cut the pipes short and plug them. Unbolt the AC compressor and disconnect from system, that is most of your weight and you might sell it for a few quid (I did) beware of the bracket low down on the engine that side, don't remove it and chuck it away as you will get a mystery oil leak, don't ask me how I know Some of the pipes are difficult to remove without removing a bunch of other stuff, I've been working on it for a while..
