I have a leaking sump gasket on the front side of the engine. I tried to get to it under the car but no sucsses. Is there any way i can take off the sump to install a new gasket without removing the engine out of the engine bay?

The easiest way would be to remove the engine, you could do it with the engine in but it's hard to make it a perfect seal. You will also have a problem accessing two bolts that are located at the back end of the sump, the flywheel is in the way.
