Tommy nailed it with the question...did you put in 6 qts.? The answer...NO. It only took 4 1/2 qts.(with filter). I poured in a qt this am and lo and behold steady pressure about 45 lbs. The oil reads over full so I am thinking a PO installed the wrong dipstick. Anyone have a picture and dimensions of a correct dipstick for a '59 235?
