I'm sure they are but originals were rubber and modern type he used (don't remember what they were for but think GM} were a synthetic material and not prone to the cracking and drying and heat supposedly. One thing to check also is if the baffles are in place. They were added in mid production to keep excess oil from landing on the stems. If missing, could also be contributing (with combination of bad seals) to the problem. See Jan, 56 service counselor.
