1986 CADILLAC DEVILLE Engine And Engine Cooling Problems

CAR DEVELOPED AN OIL LEAK, I THOUGHT IT WAS THE OIL PAN GASKET. TOOK IT TO A DEALERSHIP WHO CHANGED THE OILPAN GASKET. IT STILL LEAKED OIL, SO I REMOVED THE ENGINE. I DISCOVERED THAT THE BLOCK HAD A CRACK FROM THE CRANK SHAFT TO THE CAM SHAFT ON THE REAR OF THE ENGINE. I TRIED TO ALUMINUM WELD IT ONCE, BUT IT STILL LEAKED. *AK

WHILE DRIVING INTO THE DRIVEWAY UPON RETURNING FROM WORK, PARKED THE VEHICLE, NOTICED A PUDDLE OF WATER UNDERNEATH. LIFTED UP THE HOOD, COULD SEE WATER COMING OUT OF THE ENGINE CYLINDER GASKET. *AK

DIFICULT STEERING WHEN VEHICLE IS COLD. ALSO, ENGINE LEAKS OIL. *AK
