Anyone ever hear of dumping methyl hydrate to thin out the fuel before you go for an e-test?



We use methyl hydrate at work to unfreeze air systems in our trucks, and it turns out 90% of the methyl hydrate is the same **** as gas line antifreeze.



A mechanic at work told me for my 40 litre tank, dump in 2 litres of methyl hydrate and it should bring emissions down far enough to pass..



Who else has heard of this?

Ive heard of similar things, like rubbing alcohol in the tank.

There's a simpler, legal way to pass emissions, and I'm going to implement it.



Edit: Some day. LOL

ive never had a problem passing, if you're not ported have a good tps, main cat air pump, and working acv, the emissions numbers will be almost 0.



my 12a hadd 22ppm hc at idle, and 0 everywhere else

Methyl hydrate is alcohol based or something the mechanic said.. https://www.nopistons.com/forums/pub...IR#>/dunno.gif



I was curious if you guys had heard of the methyl hydrate trick.



And this is for my stupid daytona. I gave her a tune up and she still runs a tad rich, so I was thinking of trying this "trick" until I can solve the problem. I need plates on this badboy and they won't let me plate it until I pass..

rubbing alcohol works https://www.nopistons.com/forums/pub...#>/biggrin.png

Acetone LOL?

methyl hydrate is another term for wood alcohol, methanol, methyl hydroxide.

Sweet. Well I'ma try it.

We have been over my car with a fine toothed comb after the rebuild and it would not pass in Texas.



I had to take the Bonez Hi flow cats off and put stock cats on then it passed. We checked everything thoroughly and can't figure why it won't pass. It comes up for inspection again in March and I don't know what I am going to do then.



I have all the emissions crap still on the car. Air pump, ACV, EGR Valve, Good TPS. ECU shows no problems. All the solenoids are in working order. No vacuum leaks.



The only thing I can think of now is maybe it is just an O2 sensor going bad. Is there a way to test the O2 sensor? Maybe with a volt or ohm meter?

Just replace it. Bosch Universal sensors are around $28, you just have to splice it into the factory wire. I cut the plug off the stock sensor, and spliced that to the O2 sensor. It beats the hell out of $150 for the same sensor with the plug already on it.

I had read that the Bosch do not work correctly. Maybe that was from a Mazda salesman https://www.nopistons.com/forums/pub...#>/biggrin.png



Your's works fine I suppose....

anhydrous alcohol (gas dryer) binds to the water and splits it and that reaction yields methanol and whatever the starting alcohol was, usually ethanol or isopropanol.

My bosch sensor has worked just fine. Actually, its due for replacement now.

ntk 02 sensors are usually available, and its the factory part. usually about $20.



have you checked your acv? if its not working car not pass smog. if its not working theres 2 vacuum hoses in the front of the intake by the tb that get swapped.



possibility number 3 is that the bonez cat is bad, have you looked in it?

OK but this alcohol trick will do something right? Like help me pass?

how to pass emissions?



have connections and some green., hell even i PASSED emissions with near 0 counts in every category.



kevin.

I have a connection I just got.. but I would save money if I can pass with a trick. Otherwise I gotta get hooked up and waste the money.

its a daytona, you can probably buy an identical one for the same it costs to pass emissions.



kevin.

Hahah almost. It's an extra 10 bucks. Mines an ES though so it's got the bodykit.



Ahh who am I kidding

by bodykiy you mean they made the bumper longer by like an inch or 2?



kevin.

no its like pretend lowered an inch and its got the neat bumper holes from the factory in the back and stuff

i can put holes in your bumper for free.



kevin.

sweet will you do it for my cavalier too?!

eww, i dont wanna touch a cavalier.



kevin.

whynot its the hottest winter beater ever

custom exhaust even

you ever try to reach your oil filter?



kevin.

yup i customed up the underbelly pan with my fists so i could reach it everytime



haha its funny you mention that because i bitch about it everytime and nobody sympathises

bah, you should see the newer model cavaliers, they through like 30lbs of extra **** in the way of reaching it.



ive discovered a way to them off easily.



big screwdriver, bigger hammer, woo homemade easy grip spinoff handle!



kevin.

I just got through emissions a couple weeks ago after 5 failed attempts. After giving up on everything else I added 2 gallons of denatured alcohol to the 5 or 6 gallons of g2s left in my tank and introduced a huge boost leak into one of the silicon couplers so it wouldnt boost. This brought HC, CO, and NOx all to about 1/2 what the level they were. 25% alcohol and 0 boost is good for clean air.

My Bonez cats are brand new, well brand new when inspected. They are about a year old now.



Everything seems to be working right with the ACV and airpump and everything. Obviously there is something wrong but I do not know what it is so I am going to try replacing the O2 sensor.



I found a place on the web that has the Bosch O2 sensor already with the proper connection for the 87 RX7 so apparently no wiring or splicing is needed and it is only $39.00.

gazellis, where is this place with the o2 sensor?



kevin.

When JT posted the Kick Ash mod, I kinda sat around and tried to figure out what it was. Sadly, I couldn't come up with and answer, but, I came up with an idea about emisions passing.



If it works, 20B's will be able to pass emissions with PP's etc. LOL





Basically though, there was only one drawback I could think off, but I couldn't solve the problem since I don't know much about the parts that it affects. Nontheless, I'm learnding right now. https://www.nopistons.com/forums/pub...IR#>/boink.gif

Tell us what it is..

A diesel in good running condition will win. Every time! It's a visual inspection...



My car comes with no cats from the factory. Some did, but it would have a whopping 28hp!!! Instead of a ground pounding 52hp.

The Bosch sensor is listed here. It is the first one. At least the photo looks like it has the right connector. I have not ordered it yet but it looks good.



O2 Sensor

Hell no, there'll be plenty of cutting, welding, and re-routing involved so I don't want anyone trying this and ******* **** up. So, if it works with me, I'll write it up.

OH! So its NOT very practical for a daily driven street car!

Oh it is, but it requires quite a lot of modifications.
