I JUST REPLACED THE INTAKE AND PASSENGER SIDE HEAD GASKET ON MY 4.3. DRAINED THE OIL SET THE VALVES ETC.
BEFORE I REPLACED THE GASKET WHEN U DROVE IT WATER LEAKED INTO THE EXHAUST AND IT LOOKED LIKE I WAS IN A BOND MOVIE OR SOMETHING FROM THE WHITE SMOKE.
I FIGURED IT WAS A HEAD GASKET DUE TO THE WATER LEAKIUNG OUT THE EXHAUST.SO I REPLACED THE HEAD GASKETS AND LOW AND BEHOLD IT STILL DOES IT.
COULD THIS BE FROM A CRACKED OR WARPED HEAD OR A CRACKED BLOCK MAYBE? IT LOOKED LIKE IT WAS THE #6 CYLANDER SO I TOOK OUT THE BACK 2 EXHAUST BOLTS AND THE OIL AND WATER POURS OUT THOSE 2 HOLES ALSO.
ANY TIPS HINTS HELP AS TO WHAT MAY BE WRONG?

 

You may have to replace the head bolts evertime you remove them. (use new ones.)
