got the root cause, it was a blown head gasket. The other day on my way to work in the morning. the car suddenly lost its power. it ran as if it had only 2 cylinders operational.

pressure tests showed 2 cylinders lost compression (only 7kpa or below, while others got 11 to 13). I decided to get the cam blocks removed. Head gasket was blown, coolant came into cylinders and got burned there. that was why I was losing coolant.

I bought a head gasket set and got it replaced. no coolant loss now. solved it.

Thanks guys for your recommendations and advises. I am happy now. Cheers

what the motor taken apart before the head gasket problem? very rare to hear a blown head gasket from a factory assembled motor, but glad you found the problem and resolved it quickly!
