I took my 340 Dart out for a real test drive



I did not re-touque the heads soon after I got it started. I have been told I should have done that after the initial startup.

with this information, are these symptoms of a blown headgasket or could it be something else.

thanks again guys.





Chances are the head gaskets are blown,....hopefully thats all!....where they steel gaskets, or compositions?....how did you seal them?.......plus check the head dowel heights (put the head bare on the block, with no gasket, to see it if sits flat?), see if there holding the head "off" the motor enough to allow the gasket to blow due to pressure,......before the heads go back on, have them "magged" at a machine shop for cracks, going to cost a few bucks, but better than chasing your tail later, if their cracked now!......been there, done that!
