Resealing the magnum..

Mine does the same jada said it was my plenum gasket. switched to 5 quarts 40 weight and one quart of Lucas and so far so good I will check it later and give you an update but last time I checked i was over 500 miles and hadn't lost a drop. Before I made this change I had lost 4 quarts in about 1200-1500 miles maybe.
