I noticed in a video that FlyCorvair recently posted that WW advocates installing an air/fuel meter that runs off of an O2 sensor. Now, admittedly, the sensor is not mounted inside the main stream of exhaust, but rather is in an inch-long port welded up to the pipe. My question is, is that enough for the lead in the exhaust to not have a negative effect on the O2 sensor? OR... Is this just one of those things that will have to be replaced every 300 hours, sort of a sacrificial part in order to know what you want to know.
