Here's the story. Yesterday my car's temp got up to around 220-230* on the way home from work. I think the thermo was stuck on it. It was only there for a very short period of time. I would have shut it off, but it dropped back quickly. Well, tonight I went into town to get taxes done and I noticed it was running really crappy. I got home and got out and guess what I see? White smoke billowing from the exhaust. I got it inside my shop as steam starting comin up from underneath the hood as well, not alot, but some. Water is definitely leaking from the back of the motor somewhere. White smoke is usually an indication of a cracked head or blown head gasket right? I can only pray that it's not a cracked head, considering I have $1500 wrapped up in my heads! Input? Comments?

 

Even in Missouri, this is "thermostat" weather. A lot of them will stick under these conditions. If your dash guage showed 230°, the coolant may have been at 230, or may have been much warmer or cooler. If you have an obvious coolant leak, you need to repair it. Whether it is due to damaged castings, leaking intake gaskets, or even a loose heater hose will be up to you to determine.

I can't however, tell you with any certainty that "it's not..."

All we can do is hope for you that it "ain't so".

AFR's are nice and thick so you shouldnt have to worry about them being trashed
