If they pressure tested to 30 and it held for awhile they eliminated most external leaks.
Your engine may be eating the coolant but you should be seeing a lot of white smoke/steam out the exhaust.
By the way you will probably blow the egr cooler before you get a big pressure rise from a restricted oil cooler.
Coolant flows thru the oil cooler and then feeds the egr cooler. The restricted oil cooler wiil not pass enough coolant to the egr cooler and the hot exhaust gasses cause the coolant to flash boil and rupture the cooler.
Lord I shall lead them to the water but I will not try to make them drink
