Possible Cracked Head

not sure if thts what it is yet or not, but I'm starting to think my head on s-10 is cracked. i was checking oil other day and i noticed the very tip of dipstick looked a bit milky. i wiped it off and rechecked and it had a little bit less in it every time. I havent seen anymore in it but i noticed about every 2 weeks i gotta put some water in the radiator because its getting a bit warm. other morning it was real cold and i had a bit of water running out of my exhaust. so im still not sure. havent seen anymore water in oil and i keep losing water. checked radiator for leaks or cracks and theres none in it. I wouldnt have the money to really afford a new head if thats my problem.

how long would the liquid glass hold for? my grandpa put it in a truck once and it lasted 4-5 years and i knew someone else that used it and didnt help. what do you think about it?

Response:
Don't know about the liquid glass. But it could be just a bad head gasket and not a cracked head. Go back into some of the older messages and read about the coolant problems that happened to some GM cars.

1st thing to check is your overflow tank. If it is cracked you will keep needing to add coolant. Depending on your climate you should use anti-freeze of a 50/50 mix BUT flush your system 1st to get rid of that damn GM trash they use. Moisture on the dip stick doesn't always mean a crack or leak also, espicially if you live in a high moisture density or damp envoirment or drive short distances so that the engine doesn't completely warm up. Engines that run less than an hour wont displace the moisture completely. Water from the tail pipe is also in your gas. White smoke continously from your tail pipe is a sign of an internal coolant leak.

Could just be a blown head gasket that needs to be looked at closer.
