You have to figure out where it is coming from. If you have a leak between the front cover and the front plate it can be stopped by cleaning it well and applying some RTV. I had to do this on mine and I had to remove the balancer to do it. This same procedure can be used for a leak between the plate and the block, which would appear on the rear surface of the front plate. Oil that is not under pressure can be stopped with an external fix.
