Regarding your first question: this is definitely not normal. Grinding noises
indicate metal-to-metal contact and this is to be avoided. What is the oil
pressure once the engine runs? Your description of the problem is similar to
what you get when an oil filter drains when the engine is not running. When
you start the engine, the oil pump first has to fill up the oil filter before
sufficient
pressure can build up. Do you have an inverted type of oil filter, or one with a
missing backflow flap?
Regarding the Slick-50: There is probably no knowledgable person on the net
which favours it. Nevertheless, in his MGB restoration book, Lindsay Porter has
a little section on the advantages of Slick-50 (it's in the engine section). I
guess
Slick-50 paid part of the bills for the restoration :-).
