I don't think you can do anything about it! Even when i have changed front bearings it still seems to pump it out by the litre. The best way i think to tell if it is leaking out the front bearing would be to look parrallel with the engine's flywheel and see if there is any fuel there. For example with my EVO i have fuel all on the radio plate support. If u do want to get them out i think heating up the crankcase with a hair dryer or heat gun would do the trick.
