So......Been an Interesting last couple of days........After getting the gauge cluster in and getting the starter solenoid issue resolved.......I spun the engine over and noticed I wasn't getting any oil pressure........Hummm!!!......Must have lost it's prime........So......I borrow a pressure oiler to prime the system.......it has an adapter that screws on in place of the oil filter that connects to the canister with a hose.......Add oil to the canister ......pressurize the canister with 100lbs air pressure and open the valve.......the pressure pushes the oil thru out the entire oiling system in the car........open the valve and turn the key on 40lbs oil pressure........Humm....That was easy......Take all the pressure stuff off and put the oil filter back on...(still filled with oil)......Spin the engine over........"0" oil pressure....,,.WTF !!!.........Put all the pressure stuff back on......40 lbs.........Spun the engine over with the 40 lbs pressure..........Take it off ......."0" again......Talk about getting depressed........So.......I spend a day thinking this thru......It seems that the only place this problem can be coming from is when I changed the Oil Pan and changed the oil pick-up tube.........the mounting of the pick-up tube to the pump is critical to get the "O" ring seated correctly ...........I was very careful in putting in the new tube and "O" ring, so.......I was not convinced that was were the problem was.......So......I get a hold of my friend Gordon who works at GM Tech Center and explain what's going on.......He did some research and sends me a link that shows some past similar issues with the wrong size "O" ring installed.........Humm !!!.........I just took the supplied "O" that came in the kit installed it and never gave it a second thought.......But....It was the only answer that made any sense........So.......Other that the fuel system the car is a day away from running and now I have to take it apart to check a stupid "O" Ring.......Spent the day today taking the car apart.........Ha!!..........The tube was seated perfectly.......pulled the tube down and the "O" ring was in perfect condition........then I checked it with the old one that was on the GM pickup tube......... Basically 1 mm difference in size......the "O" ring supplied with the pan was smaller..........Darn !!!!........All this work for a stupid "O" ring.......But....I get it back together ........Put the pressure oil primer on .....take it off...put the Filter on and spin the engine over........Bingo.......Oil Pressure..........Some times the littlest things cause the biggest problems.............
