I have a 1962 235 Chevy and when I replaced the valve cover gasket and readjusted my valves the other day I noticed that where the two pieces of the rocker shaft meet there is alot of oil pouring out the joint. Also if I run highway speeds around 3000 RPM for 15 -30 minutes the rockers develop a rattle like it runs out of oil. Let off for a minute and it quietes down. This is a fairly fresh motor (1.5yrs) with low miles on it but a daily driver.
Thanks in advance, Morgan
