Remove the cam to work on getting it out by eliminating the problem on the tip Are you sure it isn't oil sludge built up on the other end that you can't see I've had some that I needed to use a pry bar to force them out with sludge on them
just being sure you have the hex plug removed on the bottom, I have used spray carb cleaner and long nose pliers to help free em up. long nose vise grips should work as well.
I had that happen on a motor I wasn't willing to take apart, so I left it in there, put a block off plate over the fuel pump hole, and used an electric pump!
They can be stubborn, but the above tips should make quick work of it.
There's a good sized oil feed passage to keep the pushrod oiled. A lot of guys remove the fuel pump pushrod, and use a block off plate to cover the fuel pump hole. This leaves a significant opening in that section of oil system.
I didn't realize the pushrod had an oil supply other than splash. We need to solve this ? as I'm almost ready to test our 512 without the rod.
I see the one vertical gallery on the schematic just before the right main oil gallery but it doesn't look like it is involved with the pushrod.
With no pushrod, if there were an opening at that point, it would be a big pressure/volume loss to the rest of the oiling system, save for the front cam bearing supply. I have never heard of this??
I don't remember seeing any oil passage to any stock Mopar B/RB or Gen 2 Hemi fuel pump pushrod passages I'll look later today at two bare blocks, 383 and new World cast iron Hemi, that have in stock The number one main is oiled off the crossover oil galley from the oil pump boss in the front of the block that feeds the passenger side lifter galley, maybe that is what he is thinking of
