Valve train oil tubes
1963 F100 223 6cyl.
Well, I caught the problem before it hurt something. Heard a knocking under the valve cover when I started Alberta the other day. So I rode the bike and checked it out after I got home. Turns out one of the oil squirting tubes that runs to the top of the rocker arm shaft is loose. Hopefully, it just slipped out. Anyway, I'm planning on replacing it with new brake lines, but I'm curious if anyone has ever done this before? There are two in my engine. One for the rear bank of valves, on for the front. The one on the front actually has a jagged hole in the top of it. I'm not sure how it got there, because it's not contacting the valve cover.
What I really would like to know is if those are pressed in to the oil journals in the head. Everyone I've talked to thinks so, but I would like a definite yes or no. And any other info you guys could give I'd appreciate. Thanks in advance.

I replaced the oil inlet lines when I rebuilt my 223 back in 1998. I had to fabricate a pair myself - one was in terrible shape and the other was missing! I used break line, but I still had to do some soldering and shaping at the end of the oil inlet tube that inserts into the passage in the cylinder block. There is actually an "O" ring fitting at this end that makes for a snug fit and insures lots of oil makes it up to the rocker arm assemble. A common problem with these 223's is that the oil inlet lines are missing the "O" ring and things get sloppy, and the top end doesn't get the oil that it really needs!
I hope this helps!
