Had oil pushing everywhere on a 2.5L 89. First I had too much oil in it then a valve cover gasket, then the dipstick wasn't seated all the way. Had new lines to vacuum and PCV . Still get some oil show in the air box.
Once I had the proper amount of oil it all stopped leaking, oil pressure at speed was 70 psi.
