BN1 oil pump

["S. P. Carr" <scvc70@epix.net>]

Good afternoon all,

We're in the middle of a rebuild on a well-worn BN1 engine, and are wondering
how to tell whether the oil pump is any good.

The service manual for my MG-TD gives specs. for side and end clearances for
those pumps (tho' we wonder how many people have a feeler gauge that can
measure .0056 - .0064!), but we've not been able to find anything in the
Healey manual.   Advice, please?

Thanks,
