| Let me clarify my previous post a bit.
If you install a new shield front bearing, especially one with both shields in place, the oil will be blocked for a time until the grease goes away in the bearing. At that point, oil will pass through the shields of the bearing as easily as any liquid will. Shields are not seals. If a bad front bearing is in there and is disrupting the delicate oil seal b/t crank and crankcase, a new bearing will help those circumstances, too, provided the crank to case tolerance isn't already ruined.
There is another option for chronically leaking front ends. Boca sells a sealed ultra seal bearing. These bearings do a fair job of plugging the leak because the construction of the seals prevents the grease from working out.
