  My MGB engine has Reddi-Sleeves on both ends of the crank and I 
glooped the hell out of the tappet cover gaskets, et al,  when I built 
it up, have been knocking my self out trying to stop the oil leaks over 
the last few years.  It still "marks its territory."   I'm afraid if I 
put synthetic oil in it, it will pour out as fast as I pour it in!  (G)
