yea i heard about those, currently its ok. The reason im led to believe its this sensors popping up is because i have no leak when driving normal or idling, only the last 2 times i did a full pull.. it seems this sensor pops up under pressure blows some oil into the manifold/ tb area then reseats its self. it cant be fully removed because its hard wired into the cover, couldnt even change the o ring if you wanted.
