Sabi nila kung konti lang yung smoke from crankcase ok lang for a diesel. Sa oil filler cap usually tinitingnan. If a steady stream of white smoke is there it might be time for an overhaul.

Unless you've been losing a lot of oil between oil changes I wouldn't worry. If you are, have a compression test done.
