Oil filter issue!

Yes, I never pulled the base plate when I put the 90 on. Not sure I was supposed to. I think from taking the filter fitting off, installing the 90, then taking it back off and putting the filter fitting back on, the gasket must have broken it's seal? Fortunately, I had gasket in the parts box. It was a one piece that looks like a steering wheel. Not as shown in the manual, but identical to what came off. So, cleaned the plate and the block real good, put a real thin coat of permatex on all mating surfaces and reassembled it. Find out tomorrow if it's good! Thanks to all for the insight, hope your Independence Day was awesome!!
