I started it up and now only 3 days and it lost prime.
Turned off ignition and turned it on and it took about 20 seconds to get oil pressure.
I did use the oil accumulator and got 25 psi shot into the motor.
But oil pressure did not go up quick enough for my liking.
Wondering if they make a 1 way check valve for the bottom oil line?
Going to try again tomorrow and if I lose prime again I'm going to change out the oil filter back to my trusty WIX.


Sammy, mine does the same with the Wix and Mobil1 filters, and mine does what yours does, exactly. I am now thinking the filter is full, but the oil in the pump drains back into the engine and loses its prime. In the summer heat, I sometimes get pressure right away.

I am thinking if there is a way to prime the engine with the accumulator off of the front of the oil pump...maybe that would work???
