Engine Performance problem
1999 Daihatsu Sirion Two Wheel Drive Manual 63000 miles

Sirion 1.0L 3 cylinder. I have done a compression test on the engine all cylinders are equal in output 175.

I have also changed the valve stem oil seals but the engine pours out white smoke in the morning until it is warm. Any help out there

Maybe its condensation if not could be coolant leaking into the cylinders due to blown headgasket, cracked head or block when the engine contracts.

When the engine start reaching its normal operating temperature this is where the leak seals iself due to metal expansion.

Or get it block and pressure tested
