[Healeys] Very loud clatter tentative explanation

Previously I had posted re a very loud intermittent engine clatter.

After examing the top end thru a bore scope and dropping the pan and
examining the bores from the bottom, as well as the cam lobes, I decided to
replace the rocker assembly on the theory that at least if the problem
reoccurred it would be in the lifters or the cylinders for sure.

Yesterday I replaced my rocker assy with a 1.6 high-lifter from Rocker Arm
Specialist in Anderson, CA.

Just finished driving about 20 mi street & freeway at 85 degrees
ambient--problem seems to have disappeared.

Yesterday when I removed the orig assy and examined the pushrods, I noticed
on the pushrod for valve #3--the little cup on the end was bone dry of oil
and all the rest had visible oil in them. Oil passage in #3 rocker must have
gotten clogged.

Will post again if there are any more developments.
