I got my engine back in my car and now i have a exhaust leak in my engine bay. If im on the drivers side it sounds like its on the passenger side,and vice versa. I sealed my header gaskets with copper seal when i put them on so i just cant see it being it. It s 93' lx twin turbo so maybe its the turbo but i cant put my finger on it. Is there anything out there that i can spray to find an exhaust leak? Also, could there be something else wrong that would sound like and exhaust leak. When i had the engine out all i did was replace gaskets on heads intake and oil pan. Thanks
