You can do the hot and cold comparison. made easy with your phone / camera! And just like it sounds,pull dipstick when cold and get a picture. Then drive it with the intent of heating the oil. get it hot then snap a picture. Comparing the two pics, does the fluid get to high? or,is there room for it to grow? In an earlier post you mention the oil level was up to the port that the dipstick tube fit into.. I'd say that is high enough, was that hot or cold tho'??? If it was cold then you know the oil is going to grow and raise the level, And I don't think it should go over the seal "permanently".. But by doing the comparo you should be able to gauge where the top oil level will usually be when fully hot.
