With the help of some of the great Colorado 914 guys(notably Mike and Chris W) i got my car to pass the e-check. Read about it here.
I thought everything was fine and dandy. With my 5 year collector plates on it I never have to worry about emissions again(bring on the SBC).
But in Colorado they have these white child molester looking vans that sit on the highway entrance ramps. They use a laser to measure the emission of all the car entering. I drove by one and got a letter in the mail. Now I have to bring my car to a state inspector for another evaluation or my registration will be revoked and a $100 fine imposed. Their's no way I'm going to pass now, with no Cat an no smog pump.
The irony is my car runs better than it ever has. F-U CO

I have a CAT that will need a little fabrication to conect an EGR to (the tube out of cat is there but the mounting plate where the bolts attach is gone) and a SMOG pump that works but is very weak. I would let them go for a reasonable price.

Put it back together and take in in Samson. That does seriously suck though. I steer well clear of those vans when I'm in the 914. One of them is parked at 287 and 36 every day.

I thought the collector plates released you from emissions requirements?!?!

What's the deal?

Roadside sniffer... I'd heard that they would give you a fix it ticket of some sort if they sniffed you wrong.

Gotta head up the hill now. bye1.gif

Okay, I just did a quick check on-line, and I don't see how the mobile emissions vans can do anything at all for older cars. It specifically states that the mobile vans are ONLY for cars 1982 and newer, and that all pre-82 cars must be checked annually at an aircare station.

And since pre-82 cars are idle-only specifications, there is no way that they can take your acceleration measurements to mean anything. That, and you already ahve collector plates (right?) which means you did your job to pass emissions and were allowed to register the car as a collector vehicle.

I'd hazard a guess that only one of two things made this happen...

1) The person operating the system (wherever that was) mistyped some information and the age and status of the car were not entered properly.

2) The really high HC readings flagged them to alert you. Thing is, there is nothing I've found so far that says they'd do that.

I think some phone calls are in order... Something doesn't seem right here...

I don't think I'm going to bother putting it back together. I'm assuming a trained member of the Colorado Department of health is going to have a book opened detailing all the required components of a 76 914. I hope I'm wrong. I'm going to change my MPS again and cross my fingers.

Disclaimer: i donno nothin' 'bout Colorado...

But most collector plate requirements I am aware of exempt you from INSPECTIONS - not requirements, which are a Federal matter and do not change.

Just because you are not required to have periodic inspections does not relieve you from the responsibility of meeting the original REQUIREMENTS. Few places have had the technology to close that loophole. Looks like CO may be a pioneer. Oh boy.

1/8 of a tank of gas.
4-6 bottles of fuel line de-icer...
Advance your timing a few degrees.
After the test, go immediately to a gas station and fill the tank.
Reset your timing to stock.

Advance my timing? On the last thread I started about this topic most of the guys said to retard my timing a few degrees. Which is it?
Also I de-icer is basically alcohol right, I put a few gallons of E-85 last time on the recommendation of another.

Bummer I thought California was the only ones that had the road side sniffers. I've seen a couple of them including a portable dyno tester on the side of the road with cars getting waved in.
I've seen them at the bottom of a clover leaf ramp and wondered if you get enough speed then coast through them with the engine off if that would work.
GeorgeRud
Isn't government great! Do you have a friend in another state where you can register the car? Years ago, people used to get Vermont plates to avoid paying sales tax on the car, but I don't know if you can get plates from them as well.

Here in Illinois, we don't have to bother with emissions for antique vehicles, so I'm exempt from testing, and so far, the green nazis haven't invaded!
orthobiz
I heard all about it at Scotty's tonite. I'm here from Michigan for the Parade.

Move to Michigan:
Lots of water for fishing.
No sun to crack your dash or fade your paint.
You only need to have the car out from May through October.
No front license plates.
No requirements for emissions, no sniffers, no inspections, no nothing!

I could use some more 914 friends at home!

Paul
newto914s
That's one of the many things that bother me about this situation, I could have registered it in Ohio. I have friends there, it's exempt there, but it passed on the last try and I thought I was good. Paid $200 to register for 5 years, now what's going to happen to that if it doesn't pass, or I pay a mechanic(that certainly will no nothing about 914s) to "fix" it, and once I reach the $715 mark I'm exempt again.

advancing timing makes the car run lean.
Ice shield is pure alcohol...4-5 bottles in very little fuel makes it close to pure alcohol.

E85 has alot of additives.
Brew your own.

register it out in elbert county!

when i lived there, there were no emissions requirements. now granted, that was about 7 years ago but it may still be the case.

if elbert county is now on emissions, go check out kiowa!

good luck...

"Lean"? I doubt it. What it does is make the HC readings go through the roof. BAD idea. It also increases the CH temps dramatically, so NOX readings go up, too.

The answers? First, get a pretest to determine what you have and what you have to correct. Then do the following:
In a near empty tank, add 1/2 tank of low octane fuel
Set the valves to .016"
Set the timing to precisely where it's supposed to be, or maybe a degree or 2 retarded (after making sure the retard function of the vacuum can works properly)
Set the idle speed to 1000 RPM

Get another pretest and report back to us for further advice.

You could, but not legally. If you live and work in the state for 30 or 60 days (I don't remember which) you have to register your car in Colorado. They don't enforce it much, but I'm pretty damn sure there is a state statute.

SUNAB914
You'll can keep that stuff. Here in NC if your car is 35 years or older it doesn't even require a safety inspection. Heck, SC doesn't have it at all last I heard. Send your cars east once their not legal anymore. Man, that is rough. I guess I'll get busted one day for removing my 928 cats..
good luck, pretty soon all our cars will be going to the scrapper. Good gosh.

Is this a show car? If not, why not put on older vin plates? stirthepot.gif Isn't a '74 and older exempt? In Oregon, there are only certain counties that have these laws. You can register your car in a different county and get away with it. You just need a trusted friend/relative to let you use their address.

I don't think this has been said yet, but don't mess with your emissions on the car until you call the guys up and explain to them that your car is exempt from this nonsense.

They'll probably give you some cock 'n' bull story about how it doesn't matter, etc. Give them a second call a day or two later and talk to someone else. If it still comes out to be, "well because we say so" inform them that "your sorry it had to come to this because (fill in with conversion details)" and hang up. Go get a lawyer and explain to them exactly what has transpired and inquire what would it take to get this mess caused by some lowly bureaucrat cleaned up in your favor. Heck, it might just be a simple letter typed on a lawyers letterhead that makes it go away.

It's not your fault, it's some departments fault in the government.

You don't have to put up with this attempt because your CAR IS OLD (and exempt)!

I'm glad that down here in El Paso county we're not in the stupid AIR program anymore ... however if it comes back I'll have to just sell the Porsche, no way I'm getting it to pass easily or cheaply.

I'd start out trying A&PGirl's idea first.

Nothing "federal" about any of this. The Federal government only sets standards for the manufacturers ... this is all Colorado nonsense.

If I thought these laws really did any good I would feel different about them BUT there a so few older cars on the road now, passing more draconian emissions laws only serves to make politicians look good.

You really need to fight this. More than likely it is some private company being contracted to do this for the state, and they will say you have to pay it because they probably get a cut.

Like red light cameras, follow the money.

More than likely, you will find you are in the right and you just have to waste your time to fight it.
Mikey914
This is BS. You should be able to fight it. What is the accuracy of the system used, was the system properly callibrated, was the technicial certified to operatethe system?

Given all these questions, it was not a controlled environment, who's to say that a 1970 caddy wasn't blasting down the freeway and the winds picked up some if it's exhaust and blew it into the path of the laser and your car?

It is a freeway and your not the only car around.

Automated law enforcement you got to love it. What happend to the good old days when a offer of the law would ust pull you over and give you a ticket. I can respect that.

well, enough rambling, I would fight it.
Zundfolge
I gotta wonder about the accuracy of these things as well.

If this roadside truck is good enough, than why should we have to take half a day off work to take the car down to some Jiffy Lube where some high school dropout can put grease stains on the carpet when all we should have to do is whiz by one of these trucks at 60mph and get our reading instantly?


Another thought on this ... most of us here keep our 914s as toys. What if you relied on an old car to get to work every day?

I'd only consider selling it if it doesn't pass. I'd like $3k for it, it would come with all my spare parts(the state would effectively end my affair with 914s) and I'd even drive it to you in TX, for the cost of gas(it runs that good)

I have no intention of fighting this. I'd end up spending way more money on a lawyer than I would buying parts and I'd still end up loosing the case.

My appointment is set for the july 13th. I'm going to do the same thing I did the last time. Different MPS, some e-85, and a few degree retarded timing. If I fail, I get another free retest, I can get the car through the sniff test(i did it before). It's the guy looking for my smog pump and cat that will dam me.

FIRST NOTICE
IMPORTANT INFORMATION REGARDING: Make/Year/License/VIN
Dear Motorist,
A vehicle registered to you recently was identified as potentially high-polluting by roadside emissions testing
equipment. Roadside testing units located along Denver-metropolitan area roadways measure pollutants from vehicles
as they are driven. Pursuant to 5 CCR 1001-13, Part G, Section IV.A, a vehicle’s emissions as measured by roadside
testing units shall not exceed 3.0% carbon monoxide or 550 parts per million (ppm) hydrocarbons as hexane (1,075
ppm hydrocarbons as propane). The identified vehicle exceeded one or both of these limits within the past 30 days.
Documentation of these test results is enclosed with this notice.
DO NOT DISREGARD THIS LETTER - it is legal notification of your responsibilities under Colorado Law.
Failure to comply with these instructions WILL result in suspension of this vehicle’s registration and a $100
fine, pursuant to 5 CCR 1001-13, Part G, Section VIII.A; and 1 CCR 204-11, Rule X, Section 1001.0(cool.gif(1).
This letter is to inform you that you MUST contact the Colorado Department of Public Health and Environment to
schedule a free emissions compliance inspection. If you fail to do so within 30 days of the date listed above, the
vehicle’s registration will be suspended and you will be subject to a monetary fine pursuant to 5 CCR 1001-13, Part
G, Section VIII.A; and 1 CCR 204-11, Rule X, Section 1001.0(cool.gif(1).
Call 303-692-xxxx immediately to schedule an appointment for a free compliance inspection. Do not take this vehicle

Hmm.... I think I need to find out what Ritter's wifes license plate number is, order a replica on line, and then go search out those road side emissions testing stations in my neigbors early 70's station wagon - that is running a 950 CFM carb, headers and smokes "just a little" .....
Gint
Here's a thought...

Why not call the number and explain that the car is a 1976 model year vehicle with collector plates? That may end the situation. Especially given the fact that I'm pretty sure the limits listed in that letter are *more* restrictive than the limits for a 1988 Jeep Cherokee, let alone a 1976 model year vehicle.
jhadler
agree.gif with Gint.

It would seem to me that someone didn't notice that the car was running collector tags. There is NO specification for the 914 under load at rpm. So there is NO way to confirm that the car isn't running as it was designed...

I just called - the year does not matter.
First of all, this is a state program, with state employees (no subcontractors). The inspection guys that will be looking at your car are master techs. The guy I spoke to was a Lotus and flat head V8 specialist. The guy who does the air cooled stuff has supposably been a PCA guy "forever" - he even asked me if this conversation came up while we were at the Parade. The limits set are passable by any correctly running car - at any RPM - from any era as far back as you can go. What they are doing is trying to keep us from doing what alot of us do - get the classic plate and then modify the motor into what they deem a gross polluter. If anyone falls outside of these limits, they must go get an inspection. If anything has been modified from stock - including the removal of airpumps and cats, we could be screwed. I asked him how he was sure that these inspectors know what they are looking at. He said they "we are not the minimum wage employees that work for the usual emissions testing stations". I did forget to ask about unobtainable/obsolete parts (like the airpumps). He was nice enough - but it was like talking to a cop.
Gints philosophy is what I will be adopting - turn around and go the other way. I am running a euro rear plate with my real one in the rear window. I may just pull it down if I ever get trapped.
I did ask him when they were going to start putting these testing stations at the entrances of car shows, that way they could both kill the hobby and make a pile of money all at once. He didn't find it funny.

One last thing, these machines are taking readings in a way that if you have a lawn mower or a gas can in the bed of a truck, or if your missing your gas cap (or even have a poorly sealing one) you will most likely get that letter. He said he has seen that on several occasions - but you will still need to get the inspection.

I figured that was going to be the deal. I do believe my 914 as rich as it runs will pass the roadside sniffer because I've gone by one before. But if I see the truck when I'm driving the 914 I go the other way and avoid it completely.
banger
You could always raise the compression, and run E-85. That would keep you clean and legal.
Zundfolge
So I'm left with a couple of questions.

Assuming you live and work OUTSIDE the Denver Metro area, in an area where testing is not required, will we still get letters? If so can we ignore them?

Also, what would happen if you saw the truck, slammed down on the clutch and just coasted by him at an idle?


Be interesting to see if they make "admin edit-political link removed" an annual report and if so where we are in the next few years.
Gint
I realize that it's difficult to discuss this without mentioning politics at all. But Mike you seem to quite frequently have to add some extremely political crap in your posts. I'm going to edit your last post and remove it. It's against the rules. Please cease and desist.

As for your question, why not call them and ask?

The guy you talked to Scott is obviously blowin smoke at least on this point because it simply isn't true.

From the letter Samson received:
QUOTE
Pursuant to 5 CCR 1001-13, Part G, Section IV.A, a vehicle’s emissions as measured by roadside testing units shall not exceed 3.0% carbon monoxide or 550 parts per million (ppm) hydrocarbons as hexane (1,075 ppm hydrocarbons as propane).

The test limits printed on the inspection sheet from my 1970 914/6 are:
CO% Limit 5.50 - Tested 3.55 at idle 8.66 at 2500 - This limit that my car passed is already above the spec in the letter, and not even performed on a dyno. It would no doubt fail the roadside test.
HC PPM Limit 1000 - Tested 397 at idle 535 at 2500 - The test measurement that the car ran and passed at testing is almost as high as the roadside letter limit indicated. And it was run at a standstill, not a dyno or on the road under load.

I have similar specs for my 72 Chevy truck and the 67 truck. The pass/fail limits for 67 or much higher than the 70 or 72 model year limits. I can't seem to find the report for my 74 914/4. But it passed testing as well... with carbs installed. But it would undoubtedly fail the roadside sniffer at the limits listed in Samson's letter. Not by much perhaps, but it would probably fail. So I amend my previous statement in an earlier post. But I remember going by the tuck at least once and I didn't get a letter. Maybe there is a tolerance or something built in.

Please explain: how does some roadside sniffer detect your emissions with a ?laser? And doesn't have to pull you over to go right to the tailpipe? How far away can they accurately do this?

Just seems beyond high tech.

Please explain: how does some roadside sniffer detect your emissions with a ?laser? And doesn't have to pull you over to go right to the tailpipe? How far away can they accurately do this?

Something I dug up. I haven't even read it myself yet.

Thanks, Mike. Dang, this thing was even invented by someone in Colorado!!!

I read most of it.
Salient points are - they claim they can test a car a second.

With "better than 10% accuracy." (The way I read that, it means it's right 10% of the time. maybe they mean each reading is within 10% of its actual value - but that's not what they say.) Any way you look at it, 10% accuracy is pretty sucky - but they also claim "Inspect & Measure" programs have the same "10% accuracy" rating, so something is wrong with the reported data...

Something I have an issue with is tailpipe height - I get the IR absorption spectrosopy. I don't see how they can sense a raised 4x4 with a tailpipe 3' off the ground one second and a lowered 914 the next.

There have been a number of threads regarding different states that seem to echo the following:

...What they are doing is trying to keep us from doing what alot of us do - get the classic plate and then modify the motor into what they deem a gross polluter. If anyone falls outside of these limits, they must go get an inspection. If anything has been modified from stock - including the removal of airpumps and cats, we could be screwed...


Given that the participants of this BBS are pretty darned smart, I don't really understand the uproar. We know that in some states our cars (1975 and older) have been exempted from annual smog testing. We also know that although we may be exempted from annual testing, we have not been exempted from meeting specific smog requirements. The argument is that once the car has been licensed, then we are free to do what we want, beacuse the states don't have any way to find out what we've done. Now that the states may have found a way to see if we cheated, we may be caught. What's the problem?

If you've made any significant changes to your smog system, or if you happened to put a different engine into your 914, and if your 914 doesn't meet smog requirements, you're may end up having to follow the law, like a lot of us do every day.

The technicality of not needing an annual test, or of getting a "classic" plate was never intended to provide you with a "Get Out of Jail Free" card. That some people here interpreted it as such poses significant risk to them.

If you are planning a "track" car, then use it at the track. Otherwise, it appears we will all have to follow the law.

Flame on.....
