80 Westy vs. California Smog Test

vanagonliebe · Posted: Fri Nov 18, 2011 11:26 am Post subject:

It looks like what I have on there will work, its just not california smog legal. I did notice that the 77' ECU had some sort of altitude adjustment to compensate for oxygen levels. The previous smog was done at sea level, I've been using my dad's shop at 3500ft to work on it so thinking that might have something to do with the richness.
I'm keeping my eye out for an 80' FI setup but there doesn't seem to be too many of them out there. I would need the: distributor, afm, ecu, throttle body and ecu/afm wiring harness, correct? Also if I could find a california FI setup would this work in conjunction with my federal exhaust and the added pre-catalytic O2 Sensor.

Also it looks like my work may be sending me to hawaii for a while. I was considering taking the westy with me, which would solve my smog issues. Does anyone know how these air cooled engines handle the warmer climate?

I think you may need to get a complete compatible FI setup. Look at Ratwell's site he gives the compatibility between different years of various parts.

Oxy sensor is wire was just stuffed down into the wiring bundle to give the appearance that it was hooked up. I'm pretty sure california requires an O2 sensor so he must have put it on to pass the visual inspection.

Oxy sensor goes to a green wire that runs in the ECU bundle. I crossed the ohmmeter from oxy wire to several pins on the ECU and it gave 25 ohm resistance to several pins but on pin 24(supposed to be oxy sensor pin) no reading... I don't know a whole lot about electric/resistance tho so not sure what that means. Engine photo is a week or so old, I did get the engine compartment sealed up nice and tight but still searching for the flaps.

I also read somewhere that 7 deg BTC is the correct timing but from oldvolkshome.com I found my 74' distributor and it says 5 ATC. Someone else said to time it at 30 BTC @ 3500rpm and when I did this it fell back to 16 ATC at idle. Any advice on how to time her?

You need to see what the CO setting is for the model year of your fuel injection and adjust accordingly. Why was an OXY senser installed? Is it hooked up to anything? Also get the air flaps and adjust the engine seal. Otherwise you should be ok.

Having trouble finding VIN info as it is the old 10 digit code (25A0125898) but I do have the federal decal on the door jam. I found a 68-79 bus fuel injection system in the classifieds and it matches up to what I currently have on there. I do remember the guy telling me he switched it over from carburated to Injected when he rubuilt it so he must have used system off one of these buses.

At this point I'm thinking of just registering at my families address out of state but want to make sure it is running correctly. Like I said it is my first vanagon but it seems to run great so is there a performance issue with the current setup or just emissions failure?

Thanks again reluctant, owe you big time for al the help

I don't know the smog laws. My stupid spell check on the phone put con instead of VIN which is what you should check to make sure you figure out which setup you have FED or CAL. Then I would get on the classifieds and see if anyone can set you up with a fuel injection set up for your car. The 1980 setup may be hard to get and it does not require an EGR. Another option if the SMOG law allows it is to go to a mega-squirt setup. If you bought it in California maybe the mechanic is liable for selling a vehicle that has the wrong set up

haha, ya at least he knows how to plug holes, got that going for him. FPR is bolted to the tin on the passenger side and the S-Boot fits alright but I believe your right it looks to be from a late 70's bus along with the ECU and AFM.

The O2 sensor is wired into the ECU wiring bundle so checked the resistance between pin 24 and O2... no reading so checked the ECU.
ECU #'s (VW 022-906-021S, Bosch 0 280 000 149) which from what I could find match up to a 1977 Manual Trans bus.
AFM #'s (VW 022 906 301 D, Bosch 0 280 200 020) supposedly from 74'-79' bus.
Distributor (VW 021 905 205 F, Bosch 0 231 173 007) from 74' Automatic Bus.
Engine # stamp is CV004380, which I believe is the correct engine. I only have the shitty haynes manual but from the exhaust diagrams I have the federal exhaust, minus the addition of the o2 sensor after the egr filter.

Am I totally screwed here or is this salvagable?

Do not worry about the distributor yet. Your van has federal fuel injection with a California exhuast if it has an oxy sender. You better check your con to figure out what type of set up that came with it. I am not sure of what the smog regulations are. The oxy sender can still be used to help narrow the co down, but it should not be hooked up to anything. Federal did not use an oxy sender. And the timing is different, 7 degrees before tdc. Try to adjust idle to 850. One of.the.federal airheads may need to correct me if I am wrong.

yes, distributor has points. Trying to track down the original, is there a good/feasible replacement for these distributors?

Also you are missing your cooling flap. That should be inplace since it directs air over the oil cooler.

That looks like a federal fuel injection engine. Are there points in the distributor?

It is a 1980 but not so sure the VW repair shop I purchased it from put the original engine back in.

If you do not have a digital idle stabilizer then you should get one. Look for the plugs they are probably plugged together because the stabilizer failed and was not replaced. Can you get a bigger picture of your engine compartment? You mentioned having the wrong distributor as well I am wondering how much your fuel injection has been tampered with.

Has a new EGR filter and idle stabilizer isn't anywhere to be founnd. Is it imperative that I have an idle stabilizer?
Did manage to get the O2 readings down to around .550-.600V with the new O2 sensor, timing, plugs and TSII sensor but still not quite there. Is it possible that my leak in the air distributor box is causing it to run rich at idle? I'm thinking that I am loosing air after the AFM, thus the engine is getting less air than it thinks it is getting... is this a reasonable deduction?

Also do not mess with the idle stabilizer plugs with the engine running!
