Hello All,

I just got my 240 rear end bolted up over the long weekend and needed to take my car into work after having it sit in the garage for the past 4 months while I finished the conversion. As my car was not tuned for the current weather (still not past 10 degrees C) I decided give the carbs a couple of flats and make sure the needle was centered.

So after fiddling around with the carbs for 10-15 minutes (right after a 10 minute drive from work) - I got the jet centered and the mixture set and then, just as I was about to shut it off, I get coolant steaming out of the overflow tube under pressure.

I shut it off and went for a read of my Haynes. According to them, this is an indication of a blown head gasket...Is there something else that would force steaming coolant out of the overflow tube? I wish I could tell you if it had overheated, but my temp gauge quit working some time ago. I've got an electric fan with a thermo switch mounted in the coolant distribution tube (on at 185 F off at 175 F) - it didn't come on.

Could this be just a stuck thermostat?

P.S. Good thing I've got a B20 on the bench in case the head gasket truly went.
