Engine temps...
I just bought an infrared temperature sensor and discovered a big discrepancy in temps on my engine. It seems that the left side (driver's) of my engine is running about 100 to 150 degrees cooler than the right side. This goes for the temp of the cylinder head and exhaust manifold. The temp of thermostat housing reads about 185 with a 180 degree thermostat. The car seems to run fine. Should I be concerned.

I would bet that the heat riser valve on your right exhaust manifold is stuck in the 'closed' or partially closed position causing it to run hot. If so, you need to fix it or, at least, wire it open. You can do some real damage to the engine if the riser valve is closed and you run it at highway speeds for very long.
