Smog pump output. Smog experts chime in

[mofoco1]

After a few weeks hiatus iI am back to work on the 79 F250 460 auto in CA. I was messing with the timing as it seems that the distributor moved and kicked it out of the legal limit. I reset it to 14* like the tag and smog guy quoted me. I got to thinking what he had said made it fail. He said that it was the too high a CO2 level. So 2 things I just found. The sensor/valve at the bottom of the air cleaner that is connected to the passenger valve cover PVC. Am I to understand that it is a temp valve that closes, cutting off vacuum at a preset temperature and allowing the flapper to open on the snorkel to allow cool air in? If this valve is faulty is it the culprit that is keeping my flapper closed all the time even when running? I have to disconnect the hose to the flapper to get cool air in. If it is bad, are these available over the counter or is it search and destroy mission to find? Secondly since the tech said I was not getting enough air could cause the failure so I am wondering if the amount of air the smog is pumping is up to the task or not. Has anyone disconnected the hose at the divertor(if that is what it's called)? while the motor is running at idle is there a large amount of air being pumped or is it just noticeable ? I could not tell if any air was being pumped or not to be honest at the divertor end. Any ideas or insight is helpful. Don't want to just go buy parts(if available) if these may not be the problems. Thanks...Mo

I cannot post pics on this site, why I dunno. A similar question was asked on the other site, where I (NumberDummy) posted the pic of the 1974/79 460 air cleaner.

Bill the actuator on the snout works when vacuum is applied. I am thinking it is that sensor on the bottom of the cleaner, isn't that what allows the vacuum to be present or not in the air cleaner or is it that other one on the side that the hose to the actuator on the snorkel connects to?

There should be no reason why you can't post pics Bill...how are you trying to do it?

 

[BKW]

I was able to post one parts catalog pic the first time I tried it. Nothing has worked since.

Works fine on t'other site.

You loading it to the gallery here or a link to a photo hosting site?

I think I clicked on the above insert image icon.

That should work, don't know why it isn't....hmmm....have you tried directly copying the URL of the image and pasting it in your reply?

^ No, and that's too damn much trouble...t'other site is much easier. ^

Are you aware that SteveBricks passed away? He was 57, died from a heart attack. I'll be 70 next month, kinda surprised that I didn't go first...considering lousy health.

Dunno, I'm a retired parts guy, not a mechanic. Ask Mil1ion, he'll prolly know and has diagrams.

Did you know I sustained a minor stroke 5 weeks ago today?

Found out I am diabetic while thinking all this time I was told I was borderline.


The attaching a photo is a 2-3 step process.

Hate to hear that Mil. I had one at age 28.

Not the smog pump. I disconnected the hose to the divertor and without disconnecting the hose to the divertor and revved the motor pumps out volumes or no divertor pumps good too. So what is keeping it from getting more air in there?

Congrats mate. I've never had to deal with that thankfully
