Sounds like a bad head gasket. You can confirm this with a compression test, and while the spark plugs are out you can inspect the piston tops, if any are steam cleaned it's a solid indication of the head gasket.

Also milky oil (looks like a **** ton of milk was poured into the oil) is another indication of a bad head gasket.

Bubbling radiator is another indication of a bad head gasket.

With the coolant loss, I'm pretty sure the piston tops and a compression test will verify.

If you are unsure of anything I am talking about just say so and I will expand to the best of my ability on any part as necessary so you can have a solid understanding to proceed with your issue.

Not that it really matters in this case but is part of the regulations for this sub section, you should provide the trim level and the model of civic you have (i.e. sedan, hatchback, etc.) and if the car is modified and what those modifications are.

Do you actually want help in diagnosing your car, or do you just want us to magically tell you the problem?

Buy/borrow/rent a compression tester, and use it.

I believe Autozone has some. You give them a deposit, and they return every penny (including tax) when you return their tool back to them.

Back when my 99 civic was overheating, I had to look for leaks so I hit up autozone for their compressor. I used it to test out my radiator cap, and I also used it to find where coolant was leaking from. Autozone also has a "block tester", which is used to diagnose a bad head gasket. I had trouble finding out my overheating problem, and the block tester confirmed that a head gasket was NOT the problem.

OP, there are all kinds of hoses that run to and from the block. My leaks were near the intake manifold (there's some small hoses that run back there, I forgot the exact location). A compressor from Autozone is your best bet to finding the leaks.

And for what it's worth, my thermostat was the cause of my overheating issue. Turns out that the thermostat was stuck closed, which was overheating my motor (no coolant was going to the block, I believe), and some of the hoses actually tore apart because of all the pressure (I had to drive my car almost on "H" for about 5 miles!)

EDIT: Just so we don't have any confusion, I'm talking about the tool that uses pressure to find leaks in your coolant system... not an actual Compression tester for your motor lol

This is the block tester from Autozone. Use it to diagnose a bad head gasket: http://www.autozone.com/loan-a-tools...er/391378_0_0/

Here is the Radiator and Cap Tester. Use it to find any possible leaks: http://www.autozone.com/test-scan-an...it/391374_0_0/

Run car to operating temp to pressurize coolant system.

Shut car off. Remove spark plugs and look in cylinders

Chances are you will see coolant.

i just want to find out is it the head gasket. also the radiator reserve tank has smoke coming out when it overheat

Unfortunately, noncompliance to the regulations is just one way to get the thread locked let alone alienate those who are knowledgeable in helping you.

People in the know don't usually take the time to help those who don't provide accurate and detailed information.
