Subaru Cylinder Head Gasket Replacement Issues

Even on a routine cylinder head gasket replacement can be pretty labor intensive but even more so on a Automatic transmission vehicle. Customer came in due to poor driveablitiy and an overheating issue. Both very common issues in a cylinder head gasket replacement on a Subaru so it's expected in a vehicle when they get around 90,000 to 120,000 miles. First thing we check is the cooling system just because its fairly simply but gives a ton of information. In our check we found that we were losing pressure with no external leaks. Pulled the oil drain plug and behold all the coolant we were missing. 

The rest of the job was pretty routine in pulling the motor so we could seperate the cylinder heads from the engine block except when it came time to actually pull the engine. For some reason the torque convertor that attaches to the flexplate at the back of the engine didn't want to seperate. We checked the bolts to ensure we didn't leave one, tried different angles & even applied a little force. Still nothing, so we removed the torque convertor with the engine. We found out there is a snout that protrudes off the torque convertor and rests in a hole in the flexplate that had received some corrosion and made them stuck together. The real issue was yet to come.
