Hi, my cousin recently purchused a 91' ls400 with about 170,000 miles. It has recently developed a nice oil leak. We found the leak and it looks like it is coming from this area. (front main seal maby?) The oil is leaking right where the arrow is pointing. The picture shown is taken from the front bottom of the engine. Does the motor need to be pulled to repair this? How involved is the fix? I really dont want to have to take this to a shop in I dont have to :(. Thanks for any and all help!!!! -Mike
