As I mentioned before I checked all fluid levels but can't tell about the engine oil the dip stick still shows at the safe line, and checked the top side of the engine no leak evidence only the bottom of the engine gets wet, Thanks.

It's hard to tell from afar on things like that. I'd put it on a lift and check it out. Leaks are a sign of danger lurking.

If you are not doing this already, my advice is to only use the appropriate full-synthetic engine oil and premium filter (e.g. PureOne, Amsoil, or Mobil 1 EP) on your car. This provides a much higher margin of safety.
