timing cover removal in frame 580ck

Hi developed a really bad oil leak at the bottom sides of timing cover today. Just put this engine in new bearings that's it...but the bottom timing cover bolts were loose when I bought it so I tightened them...well oil leaked from min 1 but now its really bad and really Dont want. To have to pull more than the radiator and pump....what's the easy way?
Thanks
