Thank you sooo much.  I have been looking all over the place for this little
bit of info on the slave. Bentley isn't very explicit on this subject and
like you everybody else on the list hasn't ever had to replace the slave,
just the master on a 4kq. I checked the interior side of the MC finding it
dry, it must be the slave fouling
