me and a buddy of mine have been having simmilar issues with our cars, they have both been leaking from the extension housing seals and both have higher speed vibration issues. mine is a lt1 m6 car and his is an ls1 m6 car. he has more of a severe leaking problem then me, on two instances the extension housing seal has blown out violently under heavy loads going down the track, and mine blew out once awhile ago and now it is just a slow steady leak that only seem to happen under load as well. both of us have never seen a drip just having the car parked but under hard loads it spits out all over the exhaust and smokes all over. what do u guys think? do u think the vibration and the leaking are related?

 

no one has any ideas?
