So I am not on the wrong track so far in breaking in the liner by having
20w-50 oil in the case, correct?  I failed the previous liner badly.
I do not want anything to go wrong this time. I can feel the hidden power
of the new liner already. No coolant/oil leak anywhere. Will see how it
spins on the freeway a few hundred miles later.
