Put the sparkplug back into # 8 cylinder and cranked it over, did not hear any air leakage.
Put 5W30 oil into Cyl # 8 and cranked for about as long as it took too get to 125 psi last time [dry] , this time with oil its closer to 133 psi.
With a lot of cranking and more oil it pushed almost to 145 psi
Thanks everyone !
