Hi, I am lookiing at a 1977 F250 Supercab Camper Special. It has the 460/C6 8100GVW. As far as I can tell it has no emissions stuff at all. NO egr, air pump, or vapor canisters. The owner has it registered in another county so when I try and register it in my county I will have to have an emissions test. Where can I find out what it should have so I can get it ready for the test? I am in AZ btw.

 

All 1973 and later FoMoCo vehicles came with an EGR valve and if the truck was sold new in CA (dunno about other states), T/E (Thermactor Emission-smog pump), Evaporative Emission System: Unleaded fuel, restrictors inside fuel filler tubes for 4 pronged (2 above, 2 below 180 degrees apart) non vented fuel caps. Back then, gas station nozzles came in two sizes, restrictors wouldn't allow larger in diameter leaded fuel nozzles to fit in.

Member of this forum has a 1976 F350 390 4V Super Camper Special (10,000 lbs. GVW), bragged in his sig pic that it didn't come with any emissions equipment, including a smog valve (PCV mandatory in all sold new in CA vehicles since 1961, other states have required PCV since the mid 1960's). I told him a PO had removed all the jazz and I could prove it.

I drove out to San Berdoo where the truck is located, looked on the Warranty Plate for the DSO code: 72, truck was sold new in NorCal. Raised the hood, looked on the right (passenger) side frame rail below the alternator. There it was, the Evaporative Emission's charcoal cannister, without anything attached to it. Hoses that routed from fuel vapor valves in fuel tanks along frame rail to cannister missing, but the retaining clips were there.

Restrictors knocked out of fuel filler tubes, 2 pronged vented fuel caps replaced 4 pronged non vented caps. EGR valve removed, holes where it mounted to the EGR/Carb spacer plate blocked off. All the T/E parts were gone, threaded holes in cylinder heads where T/E manifolds attached, plugged off. (460's have a T/E Y pipe at the back of the block that connects to both heads, check valve threads to 3rd leg of Y).

Grommet in right (passenger) side valve cover with smog valve in place, but no hose from valve to carb nipple, as it was capped off. / Left valve cover: Original oil cap has a hole in it, rubber grommet fits into hole, plastic elbow fits into grommet, hose routes from elbow to nipple on air cleaner...except: Original air cleaner replaced by a gypo, so nothing could be attached to it.

Oil cap also replaced by a gypo chromo, had no hole in it. So, not only was the original air cleaner MIA, but...so was the preheat tube, snorkle with flapper valve/vacuum motor, crankcase ventilation filter and everything else.

CA smog tests all 1976 and newer vehicles, all the emission related parts have to present and in good working order. If it cannot pass smog, it cannot be registered, it's a simple as that. There is no waiver if the parts are obsolete.

It's fix it...or park it...and this truck has been parked since 2008! And the braggadocio has been removed from the members sig pic.

 

Save yourself the headaches and pass on it.. emission equipment (finding, buying, and reinstalling) is a pain in the azz and there is no guarantee even with the equipment installed that it will pass.

If AZ has exempted certain year vehicles, then that's what I recommend pursuing.

 

My 77 F150 4x4 has none of that either,, it does have the EGR valve,,, but nothing else,, well PCV,,, and I do believe that it was purchased in AZ,,,
Some states,, depending on GVWR, had different emission requirements,,,
You should be able to go to a smog station,, with the VIN and they should be able to tell you what it came with,, check on the Driver side valve cover,, my 351Measly has a sticker that states NON-Catalyst,,, good luck!

 

I do know that it has a regular fuel guage no "unleaded fuel only" printed on it, There are no restrictors in the fuel fill tubes. I'm going to call the DEQ office today.

 

My '78 F-150 ran on leaded gas ,I think last year to do so and was a pain in emissions.

 

Just get collector insurance so you don't have to do emissions.

 

I love living in Michigan where we have no emissions laws whatsoever. Heres what you can do, buy it and move to Michigan

Everyone knows emissions laws are

 

Bill, didn't the smog requirements start before that? Those 3 Merc Marauders, 428s I bought all had pumps, Valve attached on the right side intake manifold, and pipe plumbed into the exhaust manifolds. In fact all that stuff is still on the 428 I have setting in my shop. The motor will go into one of my truck with out those goodies but I think I will save them. Never know what the ??? holes in Calif here are going to do next.

T/E (Thermactor Emission) intro'd in 1966, but I didn't make mention, because this is the 1973/79 forum, truck in question is a 1977.

If this was the 1961/66 forum, truck was an F100 I-6/352, then it could have T/E, depending on state emissions laws. CA fer sure.

C6AZ-6052-A .. Threaded Plug (1/2" -20 x 1 11/32"), used to plug T/E holes in cylinder heads: 1966/68 240/300 & 289, 1968 302, 1966/76 FE engines.
Where did you come up with this wild mule p!ss? That's ridiculous! How could collector vehicle insurance cancel US Gov't EPA & state emissions requirements?

Hell, if this was the case, CA residents could buy any 1976 and later collector vehicles and then tell the CA Air Resources Board & DMV to shove it!

But it isn't possible in CA and I doubt in any other state, it could be possible either. It's a FELONY in some states to remove emissions related equipment.

 

OK I got the scoop. A very nice lady helped me at the ADEQ offices. She dug out some book and looked up my truck. The emissions equipment that a 1977 F250 (over 6000# GVWR) is supposed to have to pass a smog check are..... drum roll.......

PVC valve & fuel vapor canisters. That is it! No EGR, no cats, no smog pumps NADA! California trucks do get the EGR. I can deal with adding the vapor canister(s) Open air filters are OK too as long as it has the PVC vent hose attatched.

 

Get her name, employee number, and have her memorialize it on official correspondence for future preference.... like for the smog tech who might battle you tooth and nail on what he believes it is supposed to have or what the AZ reference manuals state how it is supposed to be equipped.

 

OUTSTANDING!!! Love it when a plan comes together!!

 

How much of the Evap/Em system is missing? Do you know what parts are required besides the charcoal cannister to make it operational?

All the parts (there are dozens!) are obsolete except the fuel vapor valve. Kinda hot in Arid-Zon-A this time a the year to be searching one junkyard after another trying to find the missing parts.

And, since this is monsoon season, where rain pours down from the heavens, don't forget to take your bumbershoot along.

And btw: EGR valves were installed in every automakers vehicle beginning in 1973, mandated by the US Gov't. Better call nice lady back and verify, because when you go to smog it, nice lady won't be there.

 

Must be nice to live in a paradise like Michigan where your legislators have managed to keep you safe from emissions laws. I guess most people enjoy gas fumes while they wait in line for their UEC or welfare check. I remember many Michigan refugees coming out here as our welfare paid more than yours. Nice bunch of folks, barefoot and pregnant in line at the store buying formula and diapers with food stamps while 300lb flannel shirt buys beer with cash. A rusted out Pontiac was typical, always a two door so they could leave their mark on your vehicle.

From this, it appears Michigan is pretty lame:

Yea I'm OT but WTF inspires people to come to these threads with their simple solutions like "move to Michigan/BFE/SomeotherShole where we have no laws...."
