Thanks Bob,
I knew you had the experience to shed additional light on the subject.
Interesting that the 1.9s, you say always need bore.
I rebuilt my 1.9 and the case had plenty of crush on the bearing and no
ridge in the saddle.
its got 40k on it and still going strong with good oil press.
I have been hearing all sorts of stuff about the 2.1s oil press issue that
it may be related to this.
How much out of round do you allow?
Doug
