I am getting my smog check this weekend because my tempoary registration is going to expire next monday ( End Of June )

I was told it passed smog, what are my chances of passing?
I have done the following

* New spark plugs

* New Air Filter

* New Oil

* Seafoam

* New Oil and Fuel Filter

* And I wi;ll have that **** running blazing hot

its got 83k miles on my baby all stock


If i dont pass can i request a extension on my twempoary registration number? Until i pass?

I did not pass my last go around. I had taken most of my emissions stuff off, but put back on the cat and ran an electric air pump. Well the air pump failed so I did. Went back the next day with 2 gallons of denatured alcohol and passed with flying colors. The guy was amazed, but he could have been drunk from the fumes.
BTW, I filled up with the good stuff as soon as I finished.

 

U Got Pmed!

 

denatured alcohol is just one of many ways, the quesiton is do you plan on tuning the engine, or leaving it stock? if stock then take the time to do it right, if not, then get the air pump (mechanical is better, run it straight to the cat without going through the control system that is built into the stock manifold (it increase the amount of 02 immensley and then use a 50/50 miix of denatured alcohol it will make your cat run extremley hot but the trick is to roll up to the smog station with an almost empty tank, put 2 gallons of the 50/50 mix in drive it a block or two to get the mix into the carb and then smog it, it will pass, ported or not.

then pull out of the lot, go a couple of blocks away, and fill it up with normal gas (at least 10 gallos to dilute the alky mix in the gas tank). also at this time unhook your air pump and block the hose of with a plug (if not it will overheat the cat). then go home and celebrate with some 50/50 mix for yourself

Interesting.

I have an '80 12A Cali (no cat) stock build; will the same trick work without a cat, or does the alcohol show up on test as HC's?

Would love to get it past smog, but she won't quite pass even carefully tuned. Some smog parts and carb are getting old.

 

The alcohol will not show up on a test. It is just burnt as a fuel. I'm not to sure you will pass without the cat as you are in Cali and they are very strict on emissions equipment.

 

thanks!

 

needs a cat regardless, no cat equals no reburning of exhasut gasses, as well as it will not pass a visual without the cat.

Back when FL had emission testing, I had an 83 Rx-7, and with the stock air pump plumbed directly to a new cat, it passed with 87 gasoline.
I also had an 80 f-100 PU with no cat, that would pass if I adjusted the timing and idle speed.

 

Actually guys, the stock 1980 California build never had a cat in the first place. Thermal reactor, EGR and air injection only - - and God's own collection of carb mods & vacuum dodges. Cats in those days wouldn't tolerate the oil mix.

Visual can't require equipment that was not part of the original state-approved build; the car's been registered in Cali since first delivery.

Ironically, I think I'd actually be breaking the law adding a cat... as I'd be "modifying the emissions-control system." though it would no doubt help the emissions.

 

Oh, and one big question: where can I find denatured alcohol, in gallons? Not something I've seen in the local shops.

Thx.

 

try a hardware store like lowes or home depot
