I believe Pre-1977 Yes.. And also Yes...Very Bad idea to remove it.. Guaranteed to leak foreverafter!
I have never seen any reason to purge a bottom end...Unless it really should have come Apart. But, if I felt the need...I would do the "waste a quart" method...run clean oil in, till clean oil comes out!! A waste IMHO
