One job creates 3 more!

Hi folks. So I replaced the heater hose from the engine block to the front heater matrix over the past 2 days. I have significantly less skin than when I started but its done thank the lord. Never again!

As seems to be the norm with old cars whilst I was in there 3 more jobs appeared! Can I ask for some more advice please!!

1. There is a small vacuum line disconnected from somewhere. I found it when I took the rear drivers side wheel arch liner out. It runs into the boot area at the upper edge of the rear wheel arch (I'm going to guess into the ignition boxes to drive advance?) The engine end was just loose under the arch liner out, looked like it had been torn.
I can't see anywhere obvious it goes onto the intake manifold area? Does this require manifold vacuum? Easy enough to T in somewhere but I'd like to put it back where it's supposed to be in case there is a vacuum leak.
2. Whilst underneath I spotted this horror (see pic of blocked off pipe)! Underneath the the front head. What is it supposed to be connected to? I've put 3.5k miles on the car with it like this so it doesn't seem to be causing problems but I'd like to put it right.
3. OK this one started a few weeks back! My aircon belt makes a racket until its warm up or I spray it. Aircon doesn't work so I was going to ditch the belt completely when I do the cambelts this summer, but I can't see if it runs anything else from the top. If it's just the aircon pump I was thinking of simply cutting it and removing it for now, but if its running something else then clearly I can't.

Hi folks.

Steve, it’s neither. it’s a Euro car, 82 2v. exported to the US in 82 until it came back to Europe in 89. It has some US kit on it, side markers, front bumper. Does that change the air injection situation with it being a Euro car?

I’m guessing they put the minimum necessary on to get it on the road in the US or else when it got back to Europe most of it was stripped back off. It disappeared into storage in Switzerland for 31 years so history on it is very patchy.

I”ll check the vac pipe but I can’t see it heading anywhere else in the boot so looks like it’s disconnected. I’ll reconnect and adjust idle if needed. Be interesting to see how much difference in performance there is once it’s no longer retarded at higher load.

AC belt i just tried some silicone spray to check it was the belt making the noise. If it runs nothing else, I’ll just take the belt off, it’s not doing anything useful anyway.

Once again chaps, the help is much appreciated!

 

Ok, I’ll check some prior threads and see if I can figure out what’s on earth is going on! So it would have had a smog pump on it somewhere too?

 

Hi folks. The vacuum line runs above the rear arch liner, and down into the boot where it T”s into both Digiplex boxes. I’ve reconnected it to the manifold and the car is noticeably quicker under load. Not every day you get such a simple performance gain!

Not been under the car yet to look at the front bank but no no air injectors on the rear exhaust bank, and no smog pump.

 

Well you guys were rights. It is an air injection pipe. My car is a Euro that was exported to the US in the 80s. It has had “ports” welded into the underside of each exhaust manifold branch, now welded shut since it came back to Europe in 89
