Make sure your PCV valve is working correctly. If it, is look for a source of excessive blow-by. This could be caused by a number of things like a scratched cylinder liner or broken or cracked ring(s). If the PCV valve checks out OK the next thing would be to run a compression and leakdown check on each cylinder.
