I was wondering if anyonne has a crankase evac kit on there car and if it would effect O2 readings if it was upstream from the sensor. Any ideas?
 
I did, but not anymore. You'll want to have the valve located behind the sensor though. I'm pretty sure it would screw it up otherwise.

You'd need to run a really really good oil vapor/air seperator.

Ever notice a slight film of oil in the throttle body from the PCV?. That oil on a sensor would kill it.
 
thanks for the info...I was thinkin the same things but wasn't sure...think I'll just put both tubes over to the other collector and cap off the one that is in the collector with my O2 sensor.
thanks again
