- My credo
- I can do it fast, or I can do it right... what's your pleasure?
Been giving this a lot of thought - and I haven't seen much here on anything like it, nor explorerforum, ford-trucks (although a little discussion on the idea there from years past).
My idea is an old one, with a new twist I guess one could say. For those of us who DIY more than by the book, I came up with a possible solution to the notorious 4.0 rocker oiling problem. well, 2 possibly.
First is the one that drove me to write this so here goes:
Back in the day there were plenty of people who modded their Y block fords for oiling issues, which I understand the rocker assembly on the OHV 4.0 is actually based on. Generally speaking on those it was the entire rocker assembly that suffered from the poor oiling characteristics we OHV owners face with the pushrod end. They've had many solutions that seem to work, such as laying grooves in the shaft the rocker sits on, drilling holes through rockers, and my personal favorite which I have used to great success on my old 64 F100 Y block 292.
That is, to drill precisely placed holes in the valve cover and run oil tubes from the oil pressure sending unit location to the rocker assembly. I did it with T fittings, brass tube and short lengths of oil-safe rubber hose sans-nozzle, by pinching the middle of the valve cover ends into a 'figure 8' creating a dual cone spray pattern. by aiming them precisely at the rocker arms, it did the trick. My thought now is, with a little more careful aiming of said homebuilt oil sprayers through the valve covers directly at the valve end of the rockers, would it not assist in the notorious dry socket problem they tend to face? Especially if very carefully aimed like I said before?
Or am I simply putting too much effort in out-thinking Ford's design team on an old problem that won't go away?
