Charley:
You seem to be willing to run the engine with the valve cover
removed, so try this:
Hold the steel end of a hammer and press the wooden end firmly on
various parts of the valve train while the engine is running. When you
get to the offending part the noise will change drastically.
Any hard piece of wood that won't splinter easily will do.

Developed a knock in the '55 engine and seems to be located in the
rocker arm area. The small diameter upside down "u" pipe has a hole
or split on the underside top that leaks oil when the engine is cold,
but not after it warms up. Should that hole be there?
Second, there doesnt seem to be a whole lot of oil in the rocker arm
enclosure, in fact doesn't splatter out when reving the engine with the
cover off. Should this area have alot of oil or just a heavy film on
the rocker arms from the seepage thru the little holes?
The noise or knock is pronounced at a very fast idle and is not hardly
evident at most other engine speeds. Any ideas or suggestions on what
to try?
Thanks for any and all help.
Charley
