I'm not 100% sure on this but I think the 2L block has a steel bushing in it
that the oil pump shaft rides in. It almost never gets replaced. If the
R16 blocks have the same thing then it would make more sense to hone the
bushing.
Just a thought.

Subject: Re: oil pump installation
Amen brother,
I have used motor oil and the white assembly lube in a very liberal manner.
The sucker still doesn't spin the way I think it should (too much pressure
required to turn the shaft in the block). I am going to remove the pump and
reduce the diameter of the shaft until it fits and spins like the 1600 pump
I
removed. No big deal the oil pan is still off. Will also install studs and
mount it right. Any thoughts/ advice are, as always, appreciated.
