gb20 Posted April 6, 2006 Share Posted April 6, 2006 I just got my car smoged, and suprise, suprise, it failed:cry2: . So now I have been on the phone all morning trying to find someone that can and will do a good tune up on this thing. It's a 260 and everyone I talked to won't do it because they have never worked on one before:fmad: . Anybody in Las Vegas have a good place to take our Z's? Thanks for your time. gb20 Quote Link to comment Share on other sites More sharing options...

280zwitha383 Posted April 6, 2006 Share Posted April 6, 2006 But it's a'74 right? Why does it need to pass smog? Quote Link to comment Share on other sites More sharing options...
wingnutthehutt Posted April 6, 2006 Share Posted April 6, 2006 In Las Vegas you have to smog all the way back to... I think 67. My dad moved from here to LV and had to start smogging his 69 El Camino. Quote Link to comment Share on other sites More sharing options...
gb20 Posted April 6, 2006 Author Share Posted April 6, 2006 The smog cutoff is 68. 69 and newer need to get tested. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted April 7, 2006 Share Posted April 7, 2006 Do a search on the magic gas cocktail to reduce emissions. What is it, Toluene ? Actually just do a normal tune up so it runs right and chances are you will minimize the emissions. Quote Link to comment Share on other sites More sharing options...
DavyZ Posted April 7, 2006 Share Posted April 7, 2006 If you cannot do a tuneup yourself, get it to a mechanic and tell him what you want it to do. A normally running 260Z should pass smog. Wow, I'm shocked that Kalifornia exempts the '74 from the smog checks but Nevada does not. That's stupid since Nevada's population (car's & people) is a FRACTION of my state's is.

Trevor Posted April 7, 2006 Share Posted April 7, 2006 Change the oil and replace the PCV. I know that sounds odd, but on a well seasoned engine some of the fresh gas gets by the rings and into the crankcase oil. The motor oil will absorb only so much and then and release those unburned HCs and feeds them back through the engine, increasing the amount emitted at the tailpipe.

280zrice Posted April 7, 2006 Share Posted April 7, 2006 ther are a couple of ways to approch this failed smog/ what kind of test is in vegas??? a two speed / idle test, or a dyno test at 15 & 25 mph,/ never the less , does it have a converter or no?, fuel injected or carb?? / these basic questions need to be presented inorder for proper diagnosis, scan your test and put it in your next post, Quote Link to comment Share on other sites More sharing options...
gb20 Posted April 8, 2006 Author Share Posted April 8, 2006 Here are the results of the test. Quote Link to comment Share on other sites More sharing options...
wingnutthehutt Posted April 8, 2006 Share Posted April 8, 2006 Wow, it's cheap to do a smog in Nevada.... Maybe that's why they're such sticklers for old cars. And I thought we had it bad that there was no more rolling 30 cutoff. Quote Link to comment Share on other sites More sharing options...
DavyZ Posted April 9, 2006 Share Posted April 9, 2006 At the risk of letting everyone know I should ride the short bus:ugg: , what is the pcv? PCV = Positive Crankcase Ventilation. It is a valve, probably plastic, that you should replace once in a while. Take the advice above and put a new one in, change your oil, do a tuneup. Also, buy a repair manual---they have pictures and good stuff, like information Davy Quote Link to comment Share on other sites More sharing options...
