Default blown headgasket???

OK so I went to drive to work this morning but kinda didn't make it.

So when it cold my T-stat hates to open, so the car sometime will start to spike and I just pull over when the temp gets over 3/4 and wait for the t-stat to open.

Well today, she didn't want to open. The pulled over to see some steam coming from under the hood. Open the hood to see the overflow tank bubbling. Joy

The water that was in the over flow was milky but hard to tell.

I can't tell if maybe I was low on coolant, but I never known low coolant to cause the overflow to boil. There was enough pressure to cause the cap to steam.

I don't have a compression tester to test the compression. If anyone in Atl want to come help that would be great. Please.

Thanks.

I will only mention once the how retarded it is to operate a vehicle with a known faulty component as significant as a thermostat... when they're $5 to replace. I certainly have never done anything that dumb

Things to check for blown HG.

Some kind of smoke from the tailpipe.
Pull all 4 sparkplugs and check for steam in the cylinders.
Drain coolant and check for oil.
Drain oil and check for coolant.
Check the block/head itself and see if you're leaking into the engine bay.

If none of these are present, it's doubtful your gasket has failed.

Well I will answer you first part first.

I replaced the t-stat already and it only seem to happen when it before freezing and its only happen 4-5 times, and not everytime it get cold either.

I going to check the block to see if there is coolant in there. I am not sure if my roommate has work, so I can go get oil so I can drain my oil. Atleast I was going to do an oil change anyway.

As for smoke... yea it was smoking a little more then normal this morning but the weather been weird here in Atlanta so couldn't tell if it was the cold.

BTW thanks for a speedy replay.

oh and sorry to make it sound the t-stat was a really bad problem..

well I just flushed the coolant and the oil.

The coolant had a weird brown tint at first then it was normal. I did have slush in the rad, there was still some flow but majorly blocked. I am thinking that maybe the rad was blocked enough to not allow enough flow, there for causing it to overheat.

I going to keep my eye on it and watch it for the next month to make sure there is not problem, but it drove fine to the gas station (1 mi) and back with out going above normal. As the vac is at normal so I think everything is fine.

Thanks again for the quick relay Brain and Sam

brown tint was probably rust.

that is what I hoping for. I did a coolant flush about 4 months ago and the coolant was nasty then. Figured I had gotten most of it.
