Rebuilt 10 years ago Chevy Big Block 396. I have at max 1000 miles on it. It sat about 2 years and when I started it this year (after oil change and new filter) it blows the seal off the filter. I tried a new filter, same result. Also tried a new spin on filter adapter with bypass and no luck there. Is it the oil pump? Sealed Power HV pump. The gauge slaps the max, then oil all over the floor. Never had this issue till now.
