I will use the Permatex Blue. And I just bought a torque wrench 50 to 250 inch-pounds.Once the LIM bolts are torqued to specification they will not loosen. As mentioned earlier, the gaskets shrink due to heat & contraction. That makes it appear that the bolts have loosened, but that is not the case.
