IT PASSED!!! emissions...

Featured Replies

I had to throw on my weber... And now the wagon passed emissions! It blows clean as a wissle! On the way back I got pulled over for expired tabs and it was pretty funny the cop was cool. Hes like so you are having trouble passing emissions eh? And i'm like HA! just passed today. So he wrote me a warning and commented that he had a 87 subaru wagon and he loved it, but he couldn't get it to pass emissions haha.:grin:

So did you tell him about the emissions guru? By the way, is Warren back yet? Glad to hear you passed. Got to love them Weber carbs.

By the way you should post the results of the emissions testing along with the year and model of your car/engine. That way others can guage whether a weber will work for them.

I went to Warren and he made it pass sorta... It probably would have passed with the weber even if he did nothing to it but oh well. Heres the results with the hitachi leaned out as much as it could be and de emissioned.

I believe the engine is originally from an 84 sedan. It has hydro lifters.

The car itself is an 83 gl wagon.

Matt, sometime you need to show me how you enter photos and such into your posts.

Looking good.

 

I do see that Washington let's you get away with a bit higher CO2 then Oregon Dose

The higher standard might be due to the age of the car. Older cars get higher standards. Also, after 20 years (I believe) emissions testing is no longer required. Only two more years to wait for my Brat.

im not sure how but the 84 wagon i got passed emmisions without a catalitic converter...well what was left of it. and a carb in need of some tlc. but i guess with the weber its harder to pass.

They can pass with no cat - the only way an EA81 wouldn't pass is if it were actually burning a LOT of oil. Rings almost never wear out on HO engines, so that leaves valve's. Thing about the valves is that since they lay on their sides, not much oil can get sucked though them, so burning oil is not something you typically see on an EA81. The rest is simply carb adjustments, timing, and making sure you don't have any vacuum leaks or other non-functioning accessories. From what I have seen, the cat basically only helps your cruise emmissions anyway, and even then only when you have a functioning AIS. My cruise emmissions (HC's) were around 110 without the cat, and dropped to about 35 with the cat and the functioning AIS. The limit is 220.

 

As far as passing with a Weber - should be easier since you have more adjustment, and the carb is newer (unless you use a used one). My experience has been that Weber's are more efficient than the regular Hitachi's, but considerably less efficient than the feedback Hitachi.

GD, I've often wondered about the oil burning on emissions. We used to own a '83 Mazda which burned oil to the tune of a quart every 500 miles (you could see it in the exhaust). It passed emissions!! I was told by the emissions guy that the test sees gasoline produced HCs but not oil produced HCs. I really don't know how, but I thought I'd pass this on.

Interesting - I wasn't aware of that. I guess that's why they do a "visible exhaust" test. In that case, if you have an EA81 that runs on all cylinders you should pass no problem! Hehe.

Funny, my 84 turbo wagon passed emissions on its first try and lepetitprince's brat passed on its second try after we changed the oil, air filter, PCV valve, fuel filters, spark plugs and wires.

Well you don't have as bad of luck with your wagon. Oh wait! It has a rod knock! ha!:lol:

Matt, this is hi-jacked from your earlier emissions post where you mentioned not knowing what your timing might be. Since no one's gone there for the last week, I'll drag it over to this thread.

 

Matt, I have two flywheels in the garage currently--an EA81 and an EA82. The timing marks are only 4 degrees different between the two. If you insist, I can look at them and see whether that's advanced or retarded. That should get your timing close enough to run and then you can adjust it "by ear" to eliminate pinging.

That would be helpful! It still pings slightly on the freeway under full acceleration. And galen... The wagon actually does run good now other then the slight ping at high speeds. Gets about 28mpg in the city too!

Just poke a drinking straw down the spark plug hole and watch for the disty rotor to come around to the #1 wire. You will feel when it's at TDC. Mark a line on the flywheel with a sharpie and you are in business. All you have to do then is measure out a few more marks for each degree +/- of TDC. Simple really.
