From my post on another thread about this topic asking about the same thing...
I can feel some extra resistance whenever I turn it with the drill, however the gauge, I'm told by my daughter, does not move.
Could the gauge be faulty or the oil pump be faulty? The oil filter is full after spinning oil pump.
As far as I know the pump used to work fine. Is it common they can go out?
At this point I am getting frustrated and losing motivation because I'm still NOT getting the oil up top that needs to be.
I read a bunch of posts and reasons why the oil would not come up, but they have been different reasons. None of which have seemed to be my same experience.
For some it was plugged up oil galleys, for others it was reversed head gasket, someone else had installed the bearing caps incorrectly, and others a bad oil pump. This system doesn't seem to be too complex so I'm just a little stumped as to exactly what is happening.
Here is everything I've done so far:
1. Checked that the rocker rail is installed correctly.
2. Turned oil pump with screwdriver several times with no oil coming out of rockers.
3. Turned oil pump then rock vehicle back to rotate crank slightly then turn oil pump again and still no oil.
4. Removed rail and turn oil pump to see if oil comes out of hole, there was no oil coming out.
5. Blew some air down the hole to see if it was plugged up, then turned the oil pump again and still no oil.
6. The oil filter does get filled with oil when I turn the oil pump.
7. I even used a syringe to pour oil down the hole from above the head. The oil slowly goes down.
8. Verified through pictures and just from my memory that the head gasket was positioned correct.
Do I need to remove the oil pan and just start from the bottom up? I did pull the cam but didn't touch the bearing caps, could they have gotten moved when reinserting the cam? At this point I don't know what else to do, and I'm losing hope it's something simple. In my mind I'm having to tear the entire thing apart all over again. That would be super devastating to my morale.
