Ed, just imagine how thick the smog would be in the LA basin if CA hadn't enacted pollution laws.

Pic taken in 1953 from the Hollywood/Pasadena fwy interchange facing east towards downtown LA. Smog so thick, you cannot make out LA city hall, at that time, the tallest building west of the Mississippi.

Back then, I lived in Brentwood where sea breezes wafting off the Pacific blew the smog east...towards "Anaheim, Azusa and Cucamonga."

 

It'd be like living in Michigan......

 

Let's be objective about this. CA has climatic and topographic conditions which are conducive to trapping particulate (smog) matter.. we have valleys and ranges which lead to inversion layers depending on the season. For example, cool air sinks and hot air rises, right? When there it little to no wind, the air in the valleys get trapped by the hot air above. Coupled with the number of vehicles in these dense urban areas (like metropolitan Los Angeles) then the sheer volume of exhaust (not to mention the traffic jams so everybody is idling) can quickly result in bad air quality... Arizona shares some of the characteristics of valleys and mountains... like parts of NC, WV, PA, eastern TN. They may or may not have emissions testing but I bet there are times when stale air rules the day. We just get it more often therefore the emissions laws and equipment requirements were enacted.

We on coastal California have to get tested for emissions because our dirty air gets blown into the central valley. I've seen it and it can be butt nasty. Ask anyone who lived in metro LA in the late 60s. It sometimes rained dirt.

Let's compare the situation with Michigan or other areas where there are few or little restrictions on emissions. Likely those are the flatlands where the topography and climatic conditions result in little if any suspended particulate matter. So, it all depends where one lives.

What bugs me is that my 73 4x4 logs less than 2,000 miles are year whereas there are commuters who log over 20,000 miles per year in their little Hondas and Toyotas. Who is more the polluter??? Who uses more fuel? Tires? Wear and tear of the highways? I've received bad comments about my rig only getting 10 mpg like "you're killing the planet driving that thing". I tell them to eff-off because I don't drive it every day. They are the dudley do-right hypocrites and elitists just because they drive a hybrid or a 35 mpg car and fail to look at the facts of the matter.

WTF crawled up your A$$, Id rather be in Michigan that whatever P.O.S. state your from, where people like you think there bada$$ talking ***** on the internet. Your pretty cool

 

Come on guys... Talking smack to each other over the internet is not going to do any good

V10man: I have all the smog equipment that came off my '79 F250 w/460, and I don't have any use for it (seeings how my county doesn't test). If you are needing any parts of the smog system, I probably have it.

I'm from Washington, living in CA for many years, and you're welcome.

 

Even further updates. I was able to check the emissions test results for the last time it was tested. The truck doesn't need evap system. That is good because there is NONE on it. We're down to just the pcv and the propper gas caps.

 

I would just be sure the fuel tanks are properly vented away from the engine compartment if the evap system has been removed.

 

I live in "da valley" also and just went through emissions earlier this year with my 77 F250. It was previously registered in one of the counties that doesn't require emissions testing. I passed with absolutely no emissions equipment other than a gas cap and PCV valve. One thing they did check on the PCV system was whether or not the opposite valve cover was drawing fresh air through the air cleaner.

 

Mine is not hooked up. For some reason there are 2 PCV valves, one in the valve cover and one in the oil cap. The oil cap one does not have a hose on it. WTH? When I looked at the emissions test it had "fail" for the pcv. That's probably why. So I will get the right fitting for the oil cap and run the hose to the air cleaner.

 

HI read this old thread was wondering if you had the air pump bracket and if so could you take a pic of it. thank you

 

V10man, JB78f150 may not be too far off. i was told recently that our Govt. pass a ruling that any vehicle over 30 years old would not have to pass smog. he said you would have to go to the dmv and get an antique plate and collectors ins. that's all.
i haven't ck'd it out yet because my truck isn't running yet. their just not letting this all out hoping more people will junk their old vehicles.
