On the 4.3 there are two per side..one on each side can be replaced with out to much trouble..Replace them with rubber expandable plugs, ez.. the other plugs on each side are mounted under the engine mounts.. There is several hours work alone just to get the engine mounts out of the way..If there is no foam in the oil and the leak cant be traced from the intake manifold, then it should be your freeze plug under the motor mount.. Im no authority on this..But I did stay at a motel six last night..Dave
