Martin,
I don't think there is anything OK about a bearing knock. The
problem is not going to get better and the next things that
happen are very costly.
I would stop driving it... and plan a winter rebuild... at least
the bottom end. But if you have a knock already, you probably
have some damage to the bearing shells and consequent wear on the
main and rod crankshaft surfaces. If you put in new shells with
less than perfect crankshaft surfaces... they won't last long.
Think of it has an opportunity to get a "like new" engine.

Subject: TR6 Poll: Bearing Knock
Hi kids:
I imagine I ought to be doing something more familial on
Christmas Eve,
but to
heck with the family -- I see them all the time, don't I??
Today's question is about bearing knock. Mostly because I have
some on
my '72 TR6 engine, at start-up and then again at hot idle, where
the oil
psi is about 20-25 pounds. The bearing knock at hot idle
disturbs me,
and has me contemplating at least a bottom end rebuild, but I was
wondering if others experience the same thing.
And Merry Christmas, everyone. Hope you find a short block under
the
tree!
