Got under the hood for a proper look today. Followed the vacuum schematic and it appears that, while routing was a little janky and creating some kinks, that all lines were connected appropriately, with the exception of the large diameter hose mentioned previously.Since the water pump was fitted, I've noticed the car has been hard to start. This coincided with a heatwave so figured it was a fuel evaporation issue.
However, today I noticed a large diameter vacuum pipe disconnected, and some kinked small diameter lines. I guess the shop overlooked some things... Great
I suspect that this one hose has been disconnected since the new carb went on last winter. I didn't get in and examine the setup before now, and it's only because the routing had been messed with that I noticed.Sorry you are going through that situation . I have had issues with shops making mistakes, that I had to learn to fix. The members here have helped me work through it. Sounds like you are good at figuring out your situation.
I had the same mental issue with my ‘68. But after several years I have to admit that it’s dead reliable. Wifey insists on keeping our AAA membership with 100 mile towing. I never expect to use it, but the thought of driving my El Camino 99 miles from home doesn’t concern me any longer.A week ago I took my Caballero to the Ft Lauderdale airport (55 miles). I went to Oxnard, Ca. That was the longest trip since I bought it just because I have a trust issue and I think something mechanical is going to break. It sat for 8 days but started up with no hesitation. I drove it back home with no issues. I have to get over my insecurities with this truck because it performs the way it should, except for the poor air flow from the AC. Can anyone offer me some words of encouragement?
NJ to Florida? I did the same trip but not in the Caballero. Atlantic City to West Palm Beach in a Wrangler. I'm feeling better about it's reliability and I will continue to use it. Thanks for all of your input and encouragement.After 2 summers working on it I drove my 79 original 305 1050 miles from NJ to Florida. Never missed a beat. Ran the air all second day. Got 20-21 mpg running 70-75 mph. That cured me of any doubts. It did use a quart of oil. I have did valve seals since and cured that problem.

Chase the line from the cannister. It should hit a purge valve. K is the main inlet from the cannister, the valves just allow it to function at startup/idle. Once the engine warms up, those valves shut the smog down, so that whole line becomes useless. Its only purpose is to empty whatever fumes are in the cannister, so plugging it up renders the cannister pointless as anything other than a pressure relief when the engine isn't running. Not being able to be cleaned out, the cannister will eventually get saturated and stink like gas, even to the point of dripping gas.View attachment 149270
It's this guy that's hanging loose. Looks like it should connect to Port K on the carb, but mine is blanked off.
Everything else looks to be in place correctly so I'm at a loss as to what to do haha.
Yeah I removed the bolt I'd plugged it with before a long trip this weekend. Car was running just fine.Chase the line from the cannister. It should hit a purge valve.

I think I'll go ahead and replace all those valves anyway, if they're still available. I'm sorely tempted to yank all that stuff out, along with the smog pump, but a bigger part of me wants to keep the car as original as possible.The pcv line always functions, depending on the vacuum, at idle you get max vacuum, at wot there's almost none. So having the cannister hooked to that would be ok, IF there purge valves from T/H are functional and shutting down the cannister output after engine warm up.
It's kinda trixy.
Hah, welcome to my world lol. I believe all my smog stuff is still functional and since the car is 98% original, I'm trying to keep it that way. 🚗👍😁I think I'll go ahead and replace all those valves anyway, if they're still available.
