200 ENGINE ASSEMBLY Other changes include the use of new shouldered oil pan bolts which bottom on the cylinder block rather than the oil pan, and rubber isolators installed between the heads of the pan bolts and the oil pan. Together, these isolators and the isolating gasket eliminate metal-to-metal contact between the bolts and the oil pan, significantly
reducing the amount of engine vibration transmitted to the pan. The illustration below, Figure 6-54, shows both the fiber oil pan gasket arrangement and the new isolating gasket arrangement.
