Did my 69 F250 have EGR? If so, can somebody describe how it worked and wheer it was plumbed up to?

Mine passed inspection, but there was some debate over wether or not I was suposed to have EGR.......

I'm running headers, edelbrock heads and RPM intake with a BG carb with a 14" round open air filter housing.

 

Nope.

EGR didn't even appear until '73.

It lowers NOx emissions by lowering the peak combustion temperature.

If there was debate, maybe the smog techs need a little refresher course.

 

Thanks, he swore his book said I needed it in 69.

But he could not find anywhere to plumb it on the Edelbrock RPM intake. He let me slide....

It's cool He could have found a bunch of other things if he really wanted to be difficult. I mean, ut still has the external lubrication system, the fuel tank is just laying in the bed, strapped in with some basic cargo straps for now :-)

SO, overall I'm quite happy. but, just preparing for next year...they may be even tougher.

 

Thats weird Greg, even as hard core California is on emissions, they dont require it fro cars or trucks over 30 years old..So I have heard, I havent lived there in 12 years..Just what I heard?

 

You have to smog every year? Here in CA it's every other year and 1976 and lower are exempt. Have heard that the rolling exemption was recently defeated.

I'd love to prove his book wrong but it just gets them mad.

In '69 the pickups had IMCO (improved combustion) emission controls and that was only for the F100's, the F250's and above were exempt.

IMCO was a fancy way of saying a leaner carburetor setting and revised ignition timing.

 

Im not sure. I Know that in 66 anyway I had and EGR setup and I know it was stock. However, I beleive Ford quit the EGR thing after 67. The EGR Im reffering to has nothing to do with emissions it simply recircultates the exaust through the manifold and whatnot to warm the engine up. My 66 is exempt from emissions test.=) I hate the emission tests.

 

I think you're thinking about the exhaust crossover thru the manifold and the thermostatic valve on the exhaust manifold like this one:

Yeah they did away with that in '68 on cars but you see them on some later trucks though.

 

yep thats what im talkin about.

 

And that is not EGR. As you said it is only to warm the intake manifold during cold starts. EGR actually injects exhaust gas into the intake tract to take up volume in the combustion chamber and reduce combustion temperatures. EGR system started in the early 70s in cars, mid 70s in trucks and are probably still in use on new cars today.

 

I stand corrected

 

Here in Northern Ca., Jan 1st my 76 F150 will be smog exzempt. I only have to smog a car/truck when I sell it. No inspections otherwise. There are lots of modified newer trucks running around up here with out any problems. Unless you try to sell them that is.

 

Most states just have a safety inspection. Every vehicle has to pass no matter which year. Missouri has the same thing. I hope they never start to do emmisions inspections on vehicles over 30 years. I'm guessing my truck would have to come off the road.

 

Sean, I'd be surprised. A high HP street vehicle is usually an efficient vehicle...at least it should be. I' not talking about a strictly race vehicle.

with good tuning, I bet my truck would burn cleaner than a lot of the newer vehicles on the road here in Texas that don't get tested for emissions.

 

I've had it said to me a number of times by inspectors here on Long Island, that my FE 390 or even my Triumph TR7 passed with lower numbers than many of the '80's Mustangs or GM's that had a full suite of emissions controls.

Obviously, my 390 didn't have anything, not even cats, and the HC and CO numbers were great, after playing with the carb just a tiny bit. My '76 Triumph TR7 had dual-side-draft Weber DCOE's on it and it only idled correctly after sitting on the emissions machine while I toyed with all four idle mix screws and idle speed. After that, it passed with flying colors, without a catalytic converter (came with one stock).

So yeah, there is something to be said for our hopped-up motors, the visual inspection is what usually gets us in trouble - ironic how not having an EGR will fail you, while your motor is probably burning cleaner than it was stock from the factory...

Here on Long Island, I've never had a visual inspection, but lately they have gotten more nervous. The guy I usually use told me a story how an EPA/DOT guy came down with a car with all the emissions stuff disconnected - EGR, etc had no vacuum hoses... and left the car to be inspected. When he came back, the shop owner told him that he couldn't pass him and that he should go get all that stuff put back on before trying it again. Guess what? He was cited for NOT doing the inspection and failing him outright, based on the visual inspection... he should have put it on the machine, done all the right things and just failed him without trying to give the guy a break.

 

Just another example of a government beuracracy with wayyyyyyy to much time, and money, on its hands. My sonbe took his car in and the hose from the exhaust to the air cleaner had come loose. The guy pointed it out, my son started to re-connect it sliding back where it belongs, and the guy said no. Said he had to take it to a certified garage and have it done and then bring the paperwork back proving it was done by a certified mechanic. REDICULOUS.

Obviously didn't do that. He took it to a friend at Sears, and the guy signed off on it so he could get it passed. Hopefully I won't have any issues when I get this build done. AZ does not exempt vehicles after '67 from what I hear but there wan't any smog stuff on the truck to begin with. I HATE brainless government clones.
