Default CAL ONLY Suzuki Samurai issues

I was thinking of a CA ONLY based Thread for an exchange of ideas on dealing with CA SMOG TEST issues specific to CA. We have some of the toughest standards here, and sharing of information may be helpful to all owners of Samurais, especially the 86-89 models that have carbs.
Having said that, I have found finding some parts troublesome, let alone literature or service books that are NOT in the $200 range. I am disappointed with the Chilton Manual I bought, especially with pages filled with model years that make it very confusing and cumbersome.........
In review of the many so called "experts" on line, stores, etc., it seems some have no clue on emissions in CA save one, PetroWorks. If you have not been there, they have a super Tech area that answers a lot of questions in print at N/C. Shout Out here for them for doing that.......

So, here goes. As I look at many of the postings, multiple issues/problems and where to get parts show up quite a bit on these forums. I think the sharing of information on products, including OEM parts or who has parts that will work on the Sammy would be helpful. I think this will be important to all Samurai fans, especially with US Suzuki pulling out of the USA.

An example would be the STOCK [Vapor Storage Canister] for the 1987.
One looks on line, and nothing pops up except rusty ones on E-BAY, and who knows how many miles are on that one. Suzuki say to change at 60,000 - yeah right.... try to find one new.

I think what needs to happen if for one of the MAJOR Samurai stores needs to step up, and find a supplier in another country where the Sammys are still being sold, and set up a parts supplier agreement with them, and bring in those parts supplies that are drying up. A store in Nor-Cal that successfully has done this is Mini-Mania.com for the old and new Mini Coopers, and they are thriving.
Additionally, many "Emission" based parts are very difficult to locate. Some are easy, such as Oxygen Sensors, and PVC valve, Oil and Coolant pressure switches, or EGR systems, but try to find a "NEW" 2-way check valve [2-wcv], or a Throttle Position Micro-switch [TP] or a Canister Purge Vacuum switching valve [CP VSV]........
Emission stuff must all work in conjunction with other components, otherwise you have a poor running rig - let alone the "visual" inspection the SMOG test requires and failure at the test. CA now lists SMOG results on the DMV website for vehicles, and SHOWS failure/Pass/and the dreaded "Tampering."

What say you folks out there? Is this something to build on, and create a data base of parts, identification of each with full description, and WHO has them at fair prices??

With so many of these neat vehicles out there, we need to support those that support us, and the 4WD sport. These "CULT" vehicles are like VW Bugs, and their staying power is strong, but only if a good solid supply of parts and information is easily available to us.
We could start by listing the basics on a good running power plant and drive train, then build up to serious off road and the multitude of accessories we all want on our rigs.......

All the later Samurais that I've seen have been either injection with the G13BB engine or diesel, there aren't that many interchangeable parts. A lot of Marutis went to Australia, its a long way for parts but its an English speaking country.

Your idea is a good one though, I have a copy of the parts database, if you want to check any numbers PM me. The Evap purge canister for the 87 is given as 18560-83000 which was used in many markets around the world.

Thanks R-Man. This is what I was looking for, a start to a "source" guide for folks. I did locate the Factory Service Manual as a download, which will help the "new" folks with pictures AND oem p/n listing and NAME of part, especially emission stuff, so identification and proper vernacular can be used. blow up schematics help in identification and location of parts for diagnostics also. As stated before, not everybody is a certified mechanic, and wasting time and money replacing the "wrong part" due to lack of knowledge. I am a KISS type, with Keep It Simple Stupid - as to understanding what needs to be repaired or replaced, with decisions made on need, not being "sold" something that "might" fix it.
This is VERY important on SMOG related items, and dealing with Emissions folks such as Cal Air Res Board (CAR because if you can't pass, you can't drive - and again if the drive train is not working right, then everything else is secondary. Most don't have endless funding sources available to "troubleshoot" and the cost of a Pro to fix it can be a serious financial problem for most.
Tune Up in a can won't cut it long term, and dependability 50 miles from Sunday can ruin one's weekend very quickly. I hope somebody in industry, like Low Range Off-Road picks up on this, and expands inventory of emission related parts as discussed.
One can't pick up a few thousand $$ worth of goodies if the damn thing won't run, or pass State Emission tests. Just look at the various forums, and you see question after question on this subject. Not everybody can just go buy a Weber and slap it in, as it is NOT CARB Certified in CA and is NOT the answer.
Remember, what happens in CA usually goes east, thus SMOG is an issue for all of us.
(Note: CARB just passed regulations that ALL Off Highway Vehicles sold new starting in 2018 will have to be CARB compliant, including motorcycles, ATV/ROV, rails and buggies, and SUV units..........)
Thanks for your input.

Yes that's coming worldwide. I'm an ECU designer for a large American corporation and we're doing a lot of work on new emission systems for off-road vehicles and also for large engines used on generators and the like.

one thing that you need to pass a smog test is a new CARB certified cat. They are stamped with the carb E.O. number on them and usually come with a 7 year warranty against manufacturing defects. Failure due to negligence or abuse voids the warranty. Oddly enough, installing one on a Samurai constitutes abusing the cat. The carbureted engine puts out so much pututants that the newer CARB approved cat will back up in 2-3 years. My solution is to weld flanges to the cat and to the exhaust pipe so that I can unbolt it after my smog test and store it for 2 years. you can put a straight pipe in it's place or an after market cat if you are concerned about the environment. The older cats did pass the HC, NOx, and CO tests, but without the CARB stamp, they will no longer be allowed to test as of january 2010 (I think it was 2010...)

Do they actually look for a CARB EO# on the cat? The shop I go just gives a quick look with a mirror to see that there is in fact a cat converter under there.

Those 50-state cats also cost several times what a 49-state part does.

IMO, a bigger problem is that even mixture feedback carburetors have a hard time providing the lean mixture (and excess exhaust oxygen) that cat converters need to function well. EFI makes that a non-issue and exhaust catalysts often last the life of an EFI engine.

I was given an '88 Samurai from out of state about two weeks ago and it's essentially a heap, but my goal is to eventually get it road legal and that means trying to get through smog. The carb has all sorts of issues; cracked vacuum lines, debris, and I think the thermostatic choke actuator is stuck(I hate those things). Oh, and cat had been removed long ago.

One thing I did notice is that many of the vacuum solenoids and valves appear to be standard Denso parts. The look just like the ones that Toyota used on their trucks around the same era, so perhaps that is a potential source of parts interchange.

I have an 88 samurai that (Knock wood) passed emissions which gives me two years until re-testing but are any of the aftermarket carbeurators like Weber, Harley etc help at all with emissions or does the stock carb need to be used?

I don't think any of them would be an improvement in the tailpipe end of things.

Crazy as this sounds when i went thru the first time it failed hydrocarbons by 3 points (and Arizona has a pretty tough test on a dyno).....Well, I way overdid it to play it safe and put in two cans of Heet and one can of Guaranteed to pass and drove it for a day like that.... the next morning i got up and went to the emissions test center and passed by an extremely large margin. I instantly went and refilled the gas tank to dilute the mixture after i passed and all has been fine since.... when the auto store i bought the stuff from seen the results they asked for a before and after copy of the report to show their friends..... I blacked out my personal info on it just in case...... By the way this vehicle didn't burn any oil so that was a big help and it had a brand new exhaust system including the Cat

High HC suggests a rich mixture. Adding alcohol (HEET®) to the fuel leans the mixture out, so that is probably why it helped you pass.

What are the limits for a CA Samurai anyway?
