Default Re: 49-53 mercury flathead oil pump help

I change the oil after each test fire just to be safe because my fuel pump was leaking into my oil. Thanks to all the barners that pointed me in the correct direction, I have since purchased a new Charlie NY pump. Once I installed it I changed the oil again.

The other odd thing is, my understanding the 8BA blocks take 4 quarts of oil. My dipstick reads full at slightly over 3. This include preloading the filter before I thread it into the block. I don't know if my dipstick is incorrect for my 8BA block. I have attached pictures for those who know the correct style. It measures 18-1/2" overall.

The low oil pressure issue is not new. I bought the car because the compression is roughly 110 on all cylinders. I have only driven it a couple of times and I need to verify the cause of the low readings on the guage. No need to trash the compression if it is something as simple as a clogged pickup.

I was, and slightly still are having carb issues. I made great progress yesterday thanks again to all the barners help.
