I was shown a neat trick years ago by a now deceased old-timer in our MG club,
who had rebuilt more engines than I have ever seen. He told me to mix a can of
STP oil treatment with a quart of oil and use it as an assembly lube for
bearings etc. This is a very slippery, high adhesion lubricant. I also filled
the oil pump with that mixture before installation. Even if it drains out,
there is enough residue to "prime" the pump even years later.
