Unhappy Emissions Help!!!!!!!!!

PLEASE HELP!!!!!!!!!!!!!!

I just bought a really beat up '71 F-100 with a 390. Tried to get it to pass state emissions, but they're telling me it's smoking too much (which must be invisible smoke but we won't get into that) and that it's burning too much oil (which must be the oil with the level that stays even all the time, but we won't get into that either). I don't wanna rebuild this motor right now, but I do want to get plates on it. In Colorado, if I can get it to pass once, I can get special plates that allow me to NEVER HAVE TO GET EMISSIONS AGAIN.

Other than this, the thing runs like a champ, and while the motor will be rebuilt, I just can't do it right now.

Does anybody have any quick-fix or temporary ideas to get that smoke down without venting it elsewhere? I'm a Mopar person and this is my first Ford... I'm learning that things are very different on this side of the fence!

Any help would be soooooooooo appreciated!

Thanks,
Kristen

Where do you live. Since it is a 71 the emissions law should not apply to you.

Change the oil and put in straight 40W along with two cans of CD2 treatment (the one for for oil burning).

no CO emissions?

Well, the oil was just changed, but I haven't tried the additives yet. Thanks for the suggestion!

I live in Colorado. You've got to get it to pass once, then you can get "collectors plates" and as long as you keep them renewed you won't have to get emission after that. Unless you know something I don't know.....

Is it a visual test you're trying to pass? If so, there's really not a lot that can be done to hide an oil burner.

If you feel really brave, you could mix in some 90W into your oil to thicken it up. I'm not sure if I'd do that, but I have heard of other people doing it.

Apparently it's the visual. It passes the numbers fine. I'd like to see what criteria they use for the visual, because it's not bellowing black smoke or anything. It hardly smokes at all, but where the tailpipes extend the panels do get a nice cover of soot. But, so does my Dodge, and it passes with flying colors.

I'm trying to find somebody in the next county to let me use them as a garage address so I can get past this whole nonsense.

It's almost 34 years old! Of course it smokes! It's a grandpa.

Maybe there is a "tune-up shop" very close by the Emission Station that will analyze your exhaust and set your carb to pass the emission test for a few $$ then after passing the test will reset the carb to run the best. The state guys hate these shops but who cares?

Are you getting the engine warm before taking it in? Anytime I've had to take a car in for inspection, I tried to run it for about 15-20 minutes on the highway first. I know you said your problem is visual, but a nice cruise might help clean it out before letting it idle at an inspection station. Probably washing the soot of the bed might be a good idea too.
