This is odd. I have a 70 Mustang with a 302. I took the intake off to replace a lifter. Resealed the intake. Drove about a block and smelled antifreeze. Pulled over and antifreeze is pumping out the overflow. About another block later and I start blowing white smoke. Obviously it didn't seal correctly. Fine. Did the gasket again, and this time it started pump,g out the overflow again, no white smoke this time. I'm extremely frustrated. I've built many of these engines. Done many intakes, never an issue. I have a trained professional do the third gasket. SAME result! Puking antifreeze out the overflow. This time it appears I have water, condensation, or maybe antifreeze out the tail pipe. Thoughts?
