When using RTV, or any gelling-type sealant on Chrysler 300 gasketed surfaces, be careful not to apply so much that a lot of the excess is extruded into the working chamber. I had a Jeep transfer case that had been rebuilt with an excess of some unknown gasket material that sloughed off and plugged the little strainer on the lube pump with subsequent failure of the transfer case. Similar excess in rocker arm covers could plug the drain holes. My experience with cork gaskets is that they continue to compress with time, requiring periodic snugging up of the fasteners to maintain a seal.
