California Emissions
« on: May 23, 2015, 11:32:48 pm »
Does anyone know how to bypass the california emissions so you dont have to use them? They are not required in my state and because of complications with finding the appropriate distributor (containing both vacuum and cal emissions) i need to bypass the california emissions!

I am a bit confused with your question because you want to get rid of the cali emissions but you need to find an appropriate distributor (containing both vacuum and cal emission)

  If your vehicle is equipped with Cali emissions it should  exceed the requirements in (what state are you in)?  The only way to eliminate  the smog requirements would be to regester it as a 73

I want to get rid or override either the california emissions on my distributor or override the vacuum on my distributor. I do NOT need the California emissions bc my state does not require it.

Your question is a bit unclear.  The CA emissions controls on your '86 K10 likely include many more components than the vacuum on your distributor.  Not knowing the stock distributer type (e.g. HEI, etc.) makes it difficult to answer as well.

Here in CA, model year vehicles 1975 and earlier are exempt from emissions requires (i.e. smog checks).  So it's common for owners of exempt vehicles to pull out all of the emissions controls.  All an internal combustion engine needs to run is spark, fuel, and compression.  In a more expanded form, that means that the engine will run with simply an ignition system (coil & distributer or crank fire), fuel (pump & metering (i.e. carburetor/injection)), and compression—which is comprised of intake, cylinder quench, and exhaust (roughly).  Theoretically speaking, all intermediary systems can be removed, i.e. charcoal filters, vacuum lines etc.  Notwithstanding, the engine's operating temp still needs to be controlled and the subsequent drivetrain components such as the transmission and the truck's auxiliary components such as the brake system need to be considered when appropriate.  For example, vacuum power brakes and automatic transmissions generally require engine vacuum for their operation (approx 14 in-Hg)...     ....just some things to be aware of when altering your engine's current vacuum system.

All things considered, you're probably best off either leaving the system as it is (i.e. as it was designed to operate) or taking on a lot more work than just bypassing one vacuum line.  Unless someone has managed to do it already and has the answer for you.

Best of luck.

What is wrong with yours?

It may be more affordable and less of a headache to rebuild the one you have.

ok I know i am asking what seems to be stupid questions , but you are saying both vacuum and cali emissions. What part of that dist do you believe are "cali emissions". I am sure you can find a vac advance hei and the ign modual , none of that is "cali emissions".
California emissions exceed most requirements of other states, but those are the standards that you must meet in california. Those standards do not apply in other states. I think that you cannot find the dist you are looking for because there is no such an item

i got a question, do you have emission testing in the state you live in? the reason i ask is cause my 91 v3500 is a cal truck with a cat. that is the only emissions it has and according to my state (maryland) if it came with it it still has to have it. and if i didnt have a cat. they would of looked in their book to see if its required or not

Like I said. Louisiana has no emissions requirements. I need to bypass the California emissions plug. I found out this distributor is part #1103465 and is made for a 5.0L 305. I replaced this engine with a 350 but it will not start without the California emissions plug. I need to know how to bypass it. it is legal to remove it if I am registering the truck in Louisiana.

I believe you are saying that you have an ESC distributor with the 4pin plug on the back? those typically don't have vacuum.  Do you have any of the other ESC modules still? computer controlled carb? if not, you can merely put a new non-esc HEI distributor in ($50 on eBay) run a vacuum line to the advance and re-time it.

There is also a wiring hack to use the ESC and bypass the computer control of it, read this:

Now, if you still have the Computer Controlled Carb, or are TBI, then you have a whole lot more issues to work out.

Yeah,we get it...."it will not start"....some more constructive details would serve you and this thread better....everyone here is trying to help. A re-read of this thread shows that there is nothing"obvious" about the details of your problem....all of the guys replying are still trying to figure it out.  So far Timthescarrd has come the closest to troubleshooting with the limited info you've given, Cal2200. You should be grateful..... 

My advice at his point has nothing to do with your distributor. ..Help the forum help you instead of repeating the same thing over and over.

in maryland there is no emission requirements also but you cant alter how it came. now this might be just for the exhaust part idk about anything else before.
maybe im taking your typing as a tude but yeah like fx said we're trying to help and get as much info as we can from you. but this situation kind of reminds me of the show "shark tank" and cause of that im out
