I can't think of any way that the timing chain would effect the oil pump chain.

And my oil pressure is steady, no bouncing that I've noticed.
I just looked at the other thread on the tensioner.
It seems the tensioner is filled with oil and the pressure is regulated by the springs pressing against the 2 check balls.
The oil then bleeds out port B to the pan. Basically a small shock or accumulator.

The only way I see it over pressurizing would be if the B port is blocked
or partially blocked. This would give you full oil pressure in the tensioner. It would also block any means for the oil to escape.
The piston would not retract eliminating the shock function making it into a solid piece of metal.
This would maintain until the pressure bled off. You backing it out a thread relieves the pressure.

Maybe a piece of trash stuck in the B port ?
