Oil leak after routin oil change

Hi I have a 2001 s 80 non turbo. After I changed oil, it has been leaking from the passenger side. I can not locate the leak. The only variable I can think of [first time working on Volvo] is that I did add oil to the oil filter about half way. Anyway, it did not leak oil before the oil change, but not is it leaking oil. Any help would be great thank you.

coincidence. though a light viscosity or synthetic will turn 1 drip into 3.

Did you replace the o ring on the filter cap, get it in the right spot and get it tight?

Thank you for responding. I did replace o ring. I thought I put o ring is same location, but on Saturday I will check. Again thank you for your hel!

Update on oil leak. Saturday I investigated the oil leak. On the engine block, above the drive axle mounting location on the passenger side, is a “hex” style bolt. The oil as best I can tell was dripping oil from there. The thing is, when I went to tighten it, i don’t believe I moved the bolt, not even a millimeter! But I must have just the littlest bit, because that did stop the leak. Thanks for all the help
