Adam, Are you referring to the oil connector (1954) in the middle of the two rocker-arm bars, which changed over the years (1959)? You will need the style of connector that matches the year of of your rocker-arm assembly, that hopefully matches the year of your head (that hopefully matches the oil-supply plumbing on the year of your block). If everything is from 1962, you will most likely want a connector as shown from in the 1959 manual (I'll check later manuals tonight). When Pre '68 Dave sees this, he'll correct and clarify what would be needed in 1962. | | | | | Joined: Dec 2010 Posts: 21 New Guy | | New Guy Joined: Dec 2010 Posts: 21 | Brad
Yes it's on the middle rocker arm support where the two shafts meet, the one that I have looks like someone pinched it with a pair of pliers.

head #3835913

is the same from 59-62.
Early part # was 3764478
later # is 3779879.
Pinching it with a pair of pliers was not uncommon.

Pinching it to change presure/ flow both ? do I replace it ? new to the hobby.
Adam | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | 1959-62 will be pinched off from the factory to give full pressure to the shafts, before that there is an over flow tube.
I would check your rockers to make sure they are 1959-62. The groove inside each rocker should be offset 1/4" from center.
If the groove is centered let me know.
If you can't find a connector PM me, I can help.

Would you please post your head date casting code? You might want to also post a link to a photo of your connector. It could be the earlier style I posted above - which style of connector does it look like (1954 or 1959)? If yours is like the one in 1954, I have seen almost all of these pinched a little at the outflow tube (perhaps to increase pressure a little?). | | | | | Joined: Dec 2010 Posts: 21 New Guy | | New Guy Joined: Dec 2010 Posts: 21 | Here a pic of my the oil connector

head casting # 3835913, date code L84, and the groves are in the center of the rocker arms.
Thanks Adam | | | | | Joined: Dec 2010 Posts: 21 New Guy | | New Guy Joined: Dec 2010 Posts: 21 | sorry the link did work , the oil connector looks just like the one from the 1954 from post above, only pinched off.
