If you get pressure turning the pump manually then the only thing left is the gear on the distributor is sheared from the shaft or the hex drive in the bottom of the distributor shaft is stripped. or the pump shaft is too short. what else is there?
I thought I updated it, I have oil pressure again. I guess maybe I didn't give it enough time when I was priming it before. still at around 50ishpsi cold idle and 20ish hot idle all the way up to around 50ish hot bringing up the rpms. I did replace the cam synchro, and it appears the cam gear was a little bit lower than the new one. I'm guessing that is one of the reasons the synchro was wearing into the block.
Right now, I'm still dumbfounded on this sound. Next I'm going to check the flex plate and torque converter nuts for signs of damage, and go back over the exhaust for leaks but I don't think either of those are it.
I changed the oil again a few days ago, the oil I drained looked good, no signs of fod or anything.
with my stethoscope I can hear the sound the best in the exhaust collectors, and in the fuel rail. I can't really hear it from the engine oil pan, the intake manifold, the valve covers, the timing cover, or bellhousing.
I have adjusted the valves a few times now, and fixed a few things I noticed that was bad with those, that helped quiet the engine down quite a bit but it's still loud. I have pulled plug wires one at a time seeing if the sound changed at all, and it didn't. I tried a little bit of a thicker oil which made no difference in sound or oil pressure.
I pulled the spark plugs out and they all seem fine; I went over the wires and don't see them shorting out anywhere.
The engine runs strong, doesn't misfire or anything but the sound is getting worse.
i ran it without the belt for a few and the sound is still there, doesn't change when the engine is hot or cold but i swear sometimes the sound just stops before starting back up a few seconds later.
