Why is water in the oil?

Answer 1

It could be a head gasket, cracked head or cracked block. also IT IS MOST LIKELY A LEAK IN THE END PORTS OF IN TAKE MANIFOLD GASKETS. WATER GOES THROUGHT THOOSE PORTS AS PART OF THE COOLING SYSTEM AND THEN INTO THE HEADS .YOU WILL HAVE TO R&R THE INTAKE,AIR CONTROLSYSTEM.AND I BELIVE THE INJECTER ASSEMBLY TO PULL THE MANIFOLD. WHILE YOUR THAT FAR.PULL OFF THE RED VALVE COVERS AND REPLACE THE GASKETS THEY ARE PERTTY CHEAP AND WORTH DOING WHILE YOUR THERE ANYWAY. YOU WILL NEED A MANUAL FOR TORQUE SPECS AND GUIDANCE.....ITS NOT HARD WITH GOOD TOOLS.IT KINDA FUN AND WOULD TAKE THE BETTER PART OF A WEEK END............OF COARSE THIS WAS NOT AS DIFFICULT ON MY 302 BOOS ENGINE AS IT WILL BE ON THE VG30E.IF YOU DO THIS JOB CONSIDER REMOVING THE HOOD ITS ONLY 6 BOLTS AND WEIGHS ABOUT 20 LBS.MY HOOD ON MY 91 MAX IS ALLWAYS UN BOLTED.I DONT LIKE WEARING A HELMET WHEN FIXING MY RIDE.....................HOPE THIS HELPS.......BUDDY MACK....... update.....I WAS AT U PULL IT TODAY AND THE HAD THE OPROTUNITY TO LOOK IN DETAIL AT THE ENGINE .SOMEONE HAD REMOVED THE INTAKE ASSEMBLEY AND MANIFOLD TO TAKE THE "...HEADS"...THERE ARE NO PORTS ON THE ENDS OF THE MANIFOLD ON THIS ONE .IT WAS A 1993 WITH A VG30E MOTOR. FROM WHAT I SAW IT WOULD BE THE HEAD GASKET,OR CRACKED HEAD THOOSE ARE THE ONLY LIKELY PLACES WERE WATER COULD EVEN GET IN.THE WATER PUMP MOUNTING AREA IS ISOLATED FROM THE BLOCK AND UNLESS ITS CRACK NO WATER COULD GET IN.ALL THE BEST.......BUDDY MACK
