I am in the process of rebuilding the oil pump in my 1999 Dodge Grand Caravan, (3.3L V6) I am wondering how to remove and replace the oil pressure relief spring and plunger from the timing chain cover. The end of the plunger is flush with the bottom surface of the cover, and I don't see any other access which would allow me to release the spring. does this need to be pryed out of the cover? Any advice would be greatly appreciated. Thanks...........Jim
