First of all dude, if your o2 sensor is fucked don't drive the fucking car and BOOST. Jeez. If your o2 sensor isn't giving proper readings then it doesn't know how much fuel to deliver. So it can either dump fuel in by the ton, or choke your engine completely. So you could have potentially melted your pistons. You got lucky in my opinion.


This information is wrong. When boosting, the ecu is in open loop due to load and throttle position, which means it is not using the reading from the o2 sensor to fuel the engine. A dead o2 sensor will give an overly rich (read safe) a/f mix in closed loop operation along with shitty gas mileage, but it's up to the fuel maps in the ecu to fuel the engine in open loop. At any rate a lean engine will melt pistons and a dead o2 makes the ecu go rich by default. Jeez.

As for Gil's problem, if you can't find the source of you coolant leak, and don't know that milky white stuff in your oil is bad, you need to take you car to someone who knows what they're doing. Sorry.
