Sir archie, baka ma-mislead si pepito7, i-clear natin.

During cold start, pag naka-idle na, okei lang na umangat angat yung tubig sa bibig ng radiator mo. why? If you have an existing radiator thermostat, it blocks most water flow sa engine mo, eh ang water pump, walang pahinga, so it still pump water and fills your radiator back with water, so ang tendecy, aangat lang ng aangat yung tubig, not until na maabot n ng operating temp ang engine, bubukas na yung rad thermostat, dun lang magiging dirediretso yung flow.

Ang mas abangan mo is yung "bubbles", if may bula bula na umaangat sa radiator, yung ang isang sign na may tama na ang head gasket.

not sure sa price ng engine oil sir,
bili ka nalang sir ng engine oil kahit 1 liter sa suking bilihan mo ng oil, as much as possible din, same oil na currently nasa engine mo na,
kaya naman DIY yan sir, top up ng onte then check dipstick, ulit ultin mo lang hanggang malapit na sa full or full n ang level. then observe.
