'left side" as you look at the engine from the front of the car or left side as you sit in the car driving it?? The distributor end is the RIGHT side of the engine

Change the valve cover gasket with the "kit" that includes plug tube seals, grommets, etc.... and change the O-ring on the distributor base... those leak a lot, too.

Put a small dab of Hondabond in the corners of the VCG when you install it.
