I was wondering if the 394 Oldsmobile rocker ***emblies had (retainer?) springs and end caps that held the rocker arms in place when the engine is running. When I got my car, the rocker ***embly did not have them, and what's even more strange is how the picture of the ***embly in the original '64 service manual doesn't show springs, but only shaft end caps. What is even more interesting, I found on a website called rockerarms.com is that there are two options: 394 1962-64 8 Olds. Rocker ***y. Hyd. Non-Adj. OL-44 394 1962-64 8 Olds. (***y. w/o Springs on Shaft) BU-66 Not sure what they entirely mean, for those who have worked on these 394s, are there really ones without springs and they work without them? Also where is a reputable source to obtain these springs and end caps? I'll also upload a pic of what my ***embly looks like. Sorry for the trouble, Bryan
I've seen them with and without. The pushrods have a slight lean towards the towers keeping the rockers in place
Interesting how Olds decided to do that. Do I still need end caps on my rocker shaft or do I have everything ?
Yes , you need them . They keep oil in the rocker shaft . The rocker arms are oiled by the shafts . the shafts get oil from a p***age in one rocker stand . Which gets oil from p***ages drilled in the heads and block . The springs were used thru '58 with the straight rocker arms . After '59 they weren't needed . Per the reason stated previously . New rocker shafts are available from Fusick Automotive . They are a good investment if you are doing an overhaul . Old rocker shafts retain dirt and sludge . New rocker arms aren't a bad idea either .
