Bumubula ang reservoir ko - help!

[it_online]

Bakit kaya bumubula ang reservoir ko kahit kakastart pa lang. Parang hinihipan ang tubig. Di naman nagbabawas ng tubig ang radiator. Wala naman halong tubig ang oil or oil ang tubig. Napa-overhaul ko na ang radiator last weekend lang. I also noticed na may tubig ang tambutso kahit mainit ang panahon. Parang di sya nauubusan ng pumapatak na tubig. Ang temp gauge ko naman eh hanggang kalahati lang. Ano kayang possible na reason nito? Di ko pa nachecheck ang thermostat kasi di ko alam kung saan makikita. Btw, my car is Nissan LEC. GA13 engine. Hope may makatulong. Thanks!

Update, parang kulay kalawang na ang oil ko pero di naman nababawasan ang tubig. Iniisip ko kung cylinder head gasket ang problema dapat mausok pero wala naman kahit konting usok. Hindi rin mahirap istart. One click nga iistart eh.

Option A

1. Make a compression test. Very easy do it yourself. Bili ka sa wilcon ng compression tester. Plug it sa spark plug then crank it. You should read somewhat 190psi or so. Pag pasado ito.

2. Do you have a fuel injected car? Some cars have coolant flowing inside the intake manifold. There is a seal in there as well este the Intake manifold gasket. If you have airgap dun it can suck amounts of air into your radiator. Sounds strange? But yes it can do that kc vacuum ung effect nya like a venturi.

Option B

Go for cheaper options. This is a more simpler trick of compression testing for poor people like me. Put a drop of motor oil inside your spark plug chamber mga 4~5 drops. Do it on piston number 1 muna. Remove all plugs.. (not the spark plug only the plugs para hindi magistart ung car)..
Start car.... Crank it a bit.... Check radiator... Do you see oil sa water? Pag meron congrats may leak ka. Repeat steps for each piston.

Next would be to check for cracks sa hoses.

Facts:
Hindi porket no white smoke ay walang topak cylinder head gasket...
Head gaskets role is just to seal the head and block together from the water coolant and oil passages. Kung konte lang tagos ng tubig sa piston hindi mapapansin ung sunog na coolant or vice versa it's pumping air into your radiator.

Compression test would be best to check.
