CHECK THE INTAKE MANIFOLD GASKETS EVEN IF IDLE IS OK.

WHEN YOU REMOVE THEM CAREFULY, YOU MIGHT SEE THE PLACE WHERE THE SEEPING TAKES PLACE. SOMETIMES THE ANGLE ON HEADS ARE MISMATCHED WITH INTAKE'S ANGLE.

FIRST CHECK THE TORQUE ON THE INTAKE. IT MIGHT SOLVE EVERYTHING, ESPECIALLY IF INTAKE BOLTS NEAR THE SUSPICIOUS CYLINDERS ARE NEEDING TO BE RE-TORQUED.

THERE ARE HEAVY DUTY THICKER INTAKE GASKETS THAT MAY SAVE YOU A TRIP TO THE MACHINE SHOP IF THE MISMATCHED ANGLES AREN'T TOO GREAT.

GOOD LUCK, B. SMITH
