Rocker oiling

Yes. But I do not press the tube in. I don’t know why Chrysler thinks it needs a press fit.

I use a slip fit. Once you peen the tube it can’t come out or leak.

I mean it can’t rattle around in there like socks on a rooster but a .003-.005 slip fit makes tubing the block a bunch easier.
What size drill and tube do you use?
