CA smog failures. I need R3Vs help.

Did you fix it?

I was joking about the PVC valve tape job.

Ok. I will have this done. Thank you.

Dude I took the PVC valve and taped it on the fender.

The only valve that you could have taped to the fender would be the evaporative control valve. The crank case vent on this car is a simple hose from the throttle body to the valve cover.

Get the smoke test done (and fix the leaks) and then have someone with a wide band O2 sensor measure the AFR at idle and up. It should be right at 14:1.

dude why the fck do you have no PCV valve OP? You need that. Put it back on. You should have failed visual as well with no PCV.

Is the failure still high NOX? That would be the engine running lean or a bad catalytic converter. Have you had a smoke test run?

Cat is only a few months old.

I should do a smoke test.

[tightithrash]

There's the last test.

E30's don't have a typical pcv system with a valve...

Ok guys 3 more fails and I'm still lost.

So far I now have
-new cat
-new plug wires
-new plugs
-new oriellys o2 sensor

My good friends who is a respected tuner recently tuned my car and it runs better than ever. We used a sniffer to check and adjust the car to what was coming out of the exhaust.

I changed the o2 sensor 2 nights ago and the plugs and failed again today

We put the smog sniffer in the valve cover and it was sniffing tons of fuel in my oil. Problem is I changed my oil like 2 weeks ago.

What can I do now? There is no PVC valve so what should I do now?

I can't seem to figure out what is going on if you have no intake leaks, new O2 sensor, have you done a smoke test?

One good thing about living in Minnesota is that Uncle Sam doesn't care about my 3" straight pipe.

High HC cause by unburned fuel check secondary ignition items
High nox can he caused by air leaks and exhaust leak

not to thread jack but you guys think a smog shop will know if you have a swapped motor like from e to i full swap?

[tightithrash]

If you can't figure it out, take it to a good mechanic.

Great information. Thank you very much.
