help me pass CA smog test please
My little brother has a 2wd 1985 22r pickup. He has recently failed the San Jose California area smog pretest. The truck has 180,000 miles and has been neglected the majority of its life I assume. I have in the last year changed the fuel filter, air filter, plugs, wires, dis cap and rotor (easy stuff). The truck is due for an oil change and will have fresh oil for the next smog pretest. I am getting ready to install a new timing chain yikes kit from engnbdr and adjust the valves. The truck is on its deathbed and will probably be scraped if I cannot get it to pass the smog test. Will the new timing chain yikes kit help it pass smog? I do not want to the waste time or money if this is not going to help. Should I only do the valve adjustment to see if it passes smog then install the timing chain kit? As a last resort I was going to add isopropanol to the gas (10, 20, 50, 80, 100%) what ever it takes to pass the smog test. Do anyone now if this will damage the truck in any way? I am worried about the fuel system and the carburetor. Before I add the alcohol or timing chain kit I will thoroughly trouble shoot the emissions system. All helpful comments will be appreciated. I am new. Is this post too long?

My girlfriends 87 corolla didnt pass the first time, I have a thread here asking for help, alot of tips to make it pass came up. The others were talking about seafoam last week I believe, do a search and im sure you'll find more info on it.
Good luck!

My 85 22re just barely passed last time,also with 188 k on it.But i've over maintained it.When you adjust the valves you can inspect the timing chain for slop.If it has little play then changing it wont help your smog readings.What failed on the test?CO ,HC , Nox ? Mines gonna need a new cat.The old motor(changed @ 130k) was burning lots of oil ,and i think that didn't help the cat.Then again it has almost 200k on the o.e. one so it's done it's job.

Man I'm glad we don't have smog tests here.. Not even inspections.
hehe
But, I would seriously doubt changing the timing chain is going to have any effect.
I'd try the O2 sensor, Tune it up. Maybe a new Cat Converter.
Check the EGR Valve. If all else fails - sell it on E-Bay to someone - where it doesn't matter.

Definitely post your numbers, that will help tremendously in zeroing in on the problem.
