I'm having a serious wtf moment, here....

[TheBeast_88K5]

So my rig failed smog for the first time in it's life....

One of the reason's, was that the timing is set to 5*.

The PO rebuilt the motor, and had it smogged last.
It passed then, but doesn't now...

Did they change the "timing" rule in the last two years?
Did I some how bump the timing?
Maybe the last smog checker let it slide?

I'm at a loss here...

I have a chip... could that have bumped the timing?

The spec is 4˚ max. The last guy that passed it just didnt' look very closely.

Loosen distributor, pull out timing light, adjust timing, and resmog.

I've run a few of my trucks at 4-4.5˚, and have had to adjust the timing in the parking lot of the smog station.

 

[munepit]

Mine is at zero. Isnt that where its supposed to be?

My blazer pinged on 87 at 0˚, so i started running at 4˚

 

[imiceman44]

the law is 3 degrees plus or minus from the stock number so 3 is the most you do legally but some might let 4 slide, but 5 will not slide.

 

[ryoken]

isn't this truck TBI?

 

[2INSANE]

I'm a noob here... How does advancing timing help?

 

[K5-CJ5]

3 deg + or - factory spec. I run at 2deg without issues. Make sure you disconnect the electronic advanced timing or you will be setting the timing wrong all day long. There is an electrical connector on the firewall that runs to the dist, it sits more to the drivers side when looking in the engine compartment. Wire colors change al lot it seems but as I recall factory is brown (but not 100% positive)

The chip wont make a difference because when they do the test the electronic advance is disconnected and the chips timing advance curve is not having an affect at that point.

TBI factory spec is 0 degrees.

Jebus, sucks to be in Cali. They've regulated the timing??!?!?!?! Just passing emissions output isn't enough? That's pretty silly.
What do you guys do when you build a custom engine? How does that fly out there?

The custom engine has to be within smog specs. Or you get a pre 75 vin for your vehicle, or a diesel vin. However there are rumors that CHP are starting to carry passive sniffers to detect vehicles that are out of pipe emissions for their vehicle.

so they actually hook up a timing light to your engine during the emmisions test??? Ugh, they are squeezing these trucks out man. it took me 4 trys to smog my old 82 with a stock ass 350 crate and q-jet. and the guys said they were making the imissions standards tougher this year.

lame.

 

[K5-CJ5]

The standards shouldnt get any tougher for an 82. they can only be tested according to factory emissions. newer cars however are consistently being made to meet tougher epa regs. And yes they hook up a timing light, its actually a probe thats connected to the smog machine and state.

Actually they are slowly making the limits lower, they are using the average numbers to filter a few out and off the roads.
I know that because I talked to the guy about it after I saw the limits drop between smog tests.
They are slowly getting the old cars off the road that way.
We will end up with a bunch of new cars and a few 75 and older cars pretty soon.

They developed the sliding scale in an attempt to do this but it fails. The reason being is that the sliding scale only takes into consideration the same model year as the one being tested. Therefore an 84 k30's sliding scale only takes into consideration other 84 k30's tested in California. The reason emission are going down on this sliding scale is because of aftermarket carbs, efi units, cats etc that do a better job handling emissions.

The goal is to get carb. vehicles off the road because they do not adjust to driving conditions like EFI. An easy and fairly inexpensive work around if you don't want to petition every 2 years is to swap the intake and carb for an new intake and stock TBI unit (has to be aftermarket intake to bolt to stock 350 heads). You then get refereed to the model year of the TBI and are good to go.

The only other alternative is to swap a 97 or older diesel get refereed as a diesel and forget about it forever.

Or until you get caught with a diesel truck with a gas engine.

yeah that's true if you do an illegal swap its a problem, but if you convert to a diesel and get it refereed as a diesel its completely legal, just make sure you don't just do a Vin swap! I have been told the CHP actually are carrying sniffers now and will actually check vins to see if they are a diesel with a gasser. It sucks! Best course of action is to do a newer year motor swap whether gas or diesel and be done with it. A 6.0 motor swap is super efficient and passes smog test (in most cases) really easily.

yep. the DEQ guy straight up told me the restrictions are getting tougher for same model year, so passing this year doesn't mean passing next year with the same rig.

so you can swap your, say 70s pickup to tbi and they will test you based on tbi imissions? for what year tbi? are all tbis tested the same 87-95?

likewise, if a 6.0 liter is swapped in out of say an 04, do they test you based on 2004 imissions standards?

if you have a diesel, do you even go to the smog test station?

 

[TheBeast_88K5]

**** all this smog bs.... Srsly.

I'm calling a guy about a 6.0L, tomoro....
