Thanks for all the concern and possible leads...

I do have my own connections with Toyota :-) and already a long time client of the same Casa :-)

The 1st confirmed problem is the Oil Pump, and that my valves were not "in-tune"... Made me think baka kaya may oil sludge (for the others) because oil pump is not working... for now I cant believe oil sludge is my culprit because my car is relatively new... and regularly serviced (no miss at all).

Parts are already with them... so they will install within 2 days and reevaluate again... I really hope it will be back to normal!
