I am thinking on the line of oil pressure being too high, not letting the
lifters behave as they should.
As one turns the engine when assembling, maybe the oil pressure relief valve
is affected. Happened once years ago.
What to do if it won't go away? Would I have to check the relief valve,
which I'm not familiar with. Could it be 'stuck'?
Should I check later, if I would adjust one, to see if the pressure is
normal again?
Has this problem come up before with others?

Sometimes a valve job is not done right. After the seats amd/or valves are
cut the springs need to be shimmed to compensate. Excessive oil pressure
will also cause this you need to check the function of the relief valve.
Running with lash can be a problem. When a lifter goes soft the plunger can
bang on the retaining ring. Once it fails the lifter can separate and drop
parts. If the plunger pr spring should catch in that slot in the case the
case is pretty much destroyed.

Hi
Yes I have done this.
I rebuilt a motor that I thought had no compression when it would run
for about 15 min the compression would drop off to zero in 2
cylinders. Basically the lifters were over charging and floating the
valves so no compression. let it sit for a day or so and it would
fire on all 4 for about 15 min again. Motor had other issues but that
one drove me crazy. After the rebuild it did it again so I set the
valves at zero and had compression issues never again.
Hope that helps
