[EF You]

sounds to me like you have either a crack in the head, a crack in the block, or a crack in the throttle body or Idle Speed Control motor. the first two mean your engine is shot, the last two give you a little hope.

heres what you do, start the car with the radiator cap off. if the radiator starts bubbling a lot of air out of it, you have a crack in either the head or the block, and engine compression is leaking into the coolant system. another way to confirm this is if your upper radiator hose tries to swell up, or by doing a compression test. another really good way is to pressurize each cylinder with air using a compression tester threaded fitting and any air line for air tools. do each one for a few seconds with the radiator cap off. if its cracked anywhere internally, it will bubble steadily from the radiator.


now, if you are lucky, which you probably arent, its just a small coolant passage in the intake system. look around the intake manifold and you will see a bunch of small black coolant hoses. they feed coolant into passages in the throttle body, ISC, and valve cover breather tube. this is supposed to keep the incoming air warmer for cold climates, or some other almost useless BS. sometimes the internal passages in those things crack, and cause coolant to suck into the intake. what you need to try is to bypass all of them. take the one that goes to the valve cover breather from the intake manifold and disconnect it. do the same for the throttle body ones and ISC ones. now, you should have an open fitting on the intake manifold and on the black pipe under the intake manifold (the one that connects the thermostat housing to the water pump) you need to connect a hose from one open fitting directly to the other. this bypasses all the intake coolant passages, but leaves very little chance for those other fittings to leak. if you just block them off, they might leak under pressure, but if you connect them to each other, they can still flow.

try that first, and if the car still blows whites smoke, start looking for another engine.
