Possible bad seal or scarred balancer, or possibly pcv system not working. Remove the oil cap, and with the engine running, put your hand over the hole with the engine running. There shouldn't be much pressure, no pressure, in fact, just air moving in and out rapidly. If you're getting a buildup of much crankcase pressure, it can damage a seal and blow oil out.
