    1985 FJ60 failed California smog due to high NOx

    Finally took the truck in to get smogged today and it passed! When I put the air injection system back together the other day I decided to prop open the ABV with a bolt to force air to the cat since my ABV didn't seem to be working properly. Not sure if that helped with the results but there...

    1985 FJ60 failed California smog due to high NOx

    I just removed the check valve on the air rail and it does indeed thread onto the pipe to the exhaust. So I suppose I might have been sent the wrong part. Turns out the air rail check valve is toast as well sooo maybe this is silly but I think I’m just going to buy another “AV8” from a...

    1985 FJ60 failed California smog due to high NOx

    I haven't attempted to take off the check valve on the air rail yet but it might not be a bad idea just to check if its functioning or not. I'll see about getting around to checking that, Ive got a day or two off from working on it to do some other things.

    1985 FJ60 failed California smog due to high NOx

    Here’s a photo of my pipe to the exhaust where the check valve connects to and a photo of the threaded part of my old broken check valve next to the threads of the new “AV8” check valve. Probably hard to tell the difference in size by this photo but the AV8 check valve slides right over the...

    1985 FJ60 failed California smog due to high NOx

    I'll take some pics in the morning. I'd be very surprised if the exhaust pipe had been changed on this truck at some point. If AV8 has the same threads then I guess I was sent the wrong part. I might just weld the threaded part from my old busted check valve to the one I got in the mail just to...

    1985 FJ60 failed California smog due to high NOx

    Thanks, so I wonder if AV8 ins't actually a match after all or if I was sent the wrong part. Oh well, started the return already. I was really hoping to avoid paying $55 for this little part if I could get away with buying a similar valve with the same threads for $12.

    1985 FJ60 failed California smog due to high NOx

    Do you happen to know if the check valve for the air injection rail is the same exact part as the check valve to the exhaust pipe? @mattressking stated on this thread the threads on the Standard Motor Products AV8 check valve were an exact match but today I took my original broken check valve...

    1985 FJ60 failed California smog due to high NOx

    Nevermind, I just got up to date with the whole check valve NLA status and ordered the standard motor product AV8 with the smaller nipple for $12 to my door. I'll probably just do as others have done and wrap the nipple with some high temp silicone tape to increase the diameter before clamping...

    1985 FJ60 failed California smog due to high NOx

    Alright guys I'm reviving my thread here again now that I'm almost done going through the truck getting it ready for smog. I rebuilt the carburetor, truck runs amazing now (secondary diaphragm was toast causing it to stumble/fall on its face under load), replaced all the vacuum hoses, repaired...

    I agree, the cruiser does feel a little clunky/awkward at a slow roll.

    1985 FJ60 failed California smog due to high NOx

    Oops I misspoke in my last post, I meant it failed at 15mph and passed at 25mph. That’s what confused me as I wouldn’t think the EGR would be active during the 15mph test. Is failing at 15mph and passing at 25mph indicative of anything specific? All other numbers are really low, NOx is a little...

    1985 FJ60 failed California smog due to high NOx

    Oh and another thing I just thought of, If my NOx numbers passed on the 15mph test but failed the 25mph test does that still mean I should be looking at the EGR? Isn't the 15mph test considered "idle" and if so I thought the EGR wasn't active during idle.

    1985 FJ60 failed California smog due to high NOx

    Found a nasty exhaust leak on the EGR J-tube. I wonder if that would be increasing my NOx numbers? I ordered a new gasket although from what Ive read on this forum they often just blow out again. Hopefully this new one will hang on long enough for the smog test. I also started doing some of the...

    1985 FJ60 failed California smog due to high NOx

    @OSS I've found a thread from 2006 by someone with a broken BSVS asking for advice and you told them they can delete the broken BSVS by looping the two vacuum lines that go to it so the metal lines are connected to each other. Is this a viable fix? If I do this on the lower pink BSVS it just...

    1985 FJ60 failed California smog due to high NOx

    Also, does anyone know if the part circled in red is a check valve or something else? Thats one of the lines that was plugged/missing on mine so I just ran a straight hose. Wondering if its missing a part.

    1985 FJ60 failed California smog due to high NOx

    EDIT: I couldn't get it started after I finished putting everything back together but realized I had taken out the "engine" fuse from the fuse box when I left town and never put it back in. Started right up once the fuse was put back. Now I guess I'll do a few of the tests from the emissions...

    1985 FJ60 failed California smog due to high NOx

    Ok so best to leave it how it is? with the plug on the metal line and with one line going to the port that's still in tact? So that switch basically closes the choke when it detects the engine is warmed up? But pushing the choke knob in will override that switch?

    D'oh.... thank you!

    1985 FJ60 failed California smog due to high NOx

    S Sorry, meant to post a photo. It’s the lower one. Any advice on if I should loop the vacuum line from one metal vacuum line back to the return or just keep the line hooked up to the port that’s still intact and plug the metal vacuum line that is supposed to go to the port that’s broken? I...

    1985 FJ60 failed California smog due to high NOx

    Just got the new vacuum line in the mail and started replacing everything. Discovered one of the BVSV ports is broken off and the vacuum line to it is capped. I’ll look for a replacement when I finish up but until then which would be the best configuration for this line if I were to run the...
