Did you turn the engine over every 90 degrees and prime for 2 rotations?Tom

Are you SURE about the rear passenger side threaded plug behind the expansion plug?
Also, 95 psi indicates too thick engine oil. Pontiac V8´s requires 10w30 (10w40 for RA engines) weight oil to flow out into lubricating locations in engine. 20w50 needs to be 120°-130°C (248°-266°F) to flow and protect engine as well as 10W30 does at 90°-100°C (194°-212°F). |

Yes did try rotating couple times,also I double checked oil plug front and rear. I've always used the rotella diesel oil I believe 15 40 in other pre prime pont engines and has worked ok.
