Good info! I've suspected mine is leaking. I've noticed some oil under the driver's side of the engine recently. The first time it looked like a puddle of 3 or 4 ounces of oil. Usually it was a few drops. Before I even had the chance to worry about it, I think it flooded the oil-level sensor with oil, causing a short that burned up the ECM! That's what seems to be the case at this moment. So don't let this problem exist for long if you can help it. I'll be posting separately on my ECM adventures if I get a chance soon.
Also here's a bulletin on changing this CCV separator.
