Hyundai 1.6-2.4L Tech Tip: Check The Weights On The Shafts Before Installing Belts
The addition of the balance belt won’t cause any problems as long as it’s timed correctly and the counterweights are in the proper position when the belts are installed.

Maintaining Your Balance: Engine Building Tips To Reduce NVH And Increase Life
Nobody would argue with the fact that engine balancing is right up there with “blueprinting” an engine. The goal is to equalize the reciprocating and rotating forces inside the engine so it will run smoother, last longer and achieve its maximum power potential. Although balancing would seem to be most important for high revving performance engines, it can also provide benefits for relatively stock engines, as well as low revving heavy-duty diesel engines.

Head Gasket Q & A
One reason head gaskets fail is because of engine overheating. If the engine gets too hot, the cylinder head can swell to the point where it crushes the head gasket (usually between the cylinders because this is the thinnest point). The extruded material and/or cracked combustion armor then provides a leak path for coolant and/or combustion gases.
