292 Inline 6 help
Hi, I have a 76 van with a 292 inline 6 motor. It passes CA smog with no egr valve or catalytic converter. State says i still need both of them installed. My exhaust manifold has no egr valve and no place to put one. It has the single barrel carb on it with a manual choke, and from what i can tell is all stock. Can any one help me out with any of this?

Re: 292 Inline 6 help
Does it still have an emission sticker? If so and it says something like non-catalyst or heavy duty emission, you should be good to go. What is the GVWR? I think the minimum for heavy duty emission is 6200. I think vans were often lumped in with Pickups for emissions regs. How is the gas gauge labeled? If it is marked unleaded fuel and is original, you may be out of luck.
My 1/2 ton 75 has a GVRW of 6200 and the HD emission so no cats, pumps, egr or such. Just a PVC and THERMAC system. Gas gauge is marked fuel instead of unleaded fuel. |

Re: 292 Inline 6 help
Here is a pic of the sticker under the hood, gas gage says fuel, and the smog paper work says GVRW is 6400. Mine is also running the PVC / Thermostatic air cleaner, with the EECS.

Re: 292 Inline 6 help
You need to find a label similar to one of these. First is from my 75. Note the 'Heavy Duty Engine' on the bottom right. That exempts it from most of the 75 emissions requirements. The 2nd is from a 1980 radiator core support I snagged at the local pull a part. Wasn't looking for one, but this one was just sitting on the end of the frame. Only had to unbolt the remaining fender and fender well. Almost pristine. Took the fender well also. Note the 'Non-Catalyst' label.
It could be that surviving 6 cyl HD vans are rare enough that your emissions check person has never seen or heard of one. If you can prove that your van is in 'As delivered' condition as far as installed emission equipment, your SPID that shows the RPO for Calif Emissions should prove you don't need any additional stuff. Good luck. OK doesn't have inspections and state law exempts 78 and earlier anyway. |

Re: 292 Inline 6 help
from what I know, they are grand fathered in ... any over so many year(s)
you can also do a little homework and print it out for them for the proof ( as what it was stock )

Re: 292 Inline 6 help
There is no grandfather law that i have found as of yet. What Im going to do is this.... They just look to see that the EGR valve is there. If it passes the emissions test they assume its working properly and thats it...no hooking it up to anything. They also just look to see that the cat is there. Im just going to add an EGR valve regardless of the fact there is not a place for it on the exhaust manifold. I am also going to put a piece of straight pipe thru an old cat and call it good. I will let you know if this works.
