The friend of minethat had the EVO with the motor oil into the primary, had a lot of Blow-By at the piston rings.
You can check the compression in each cylinder and that pressure showing will tell you IF Blow-By is present.
I Might be wrong on the compression here,,, but showing 160# and up might be good IF it IS equal in each cylinder or close...
Take a compression test if you can and see. Please post the results here.

I have done the oil change and will keep checking oil levels is it a big job to fix and how do i do it?
Cross that bridge when you find out IF it is leaking from the motor into the Primary. That seal MAY quit leaking if leaking because it had set for a long time'
Depends on your ability to do repair. A good HD manual (big one) for that bike would do you a lot of good. Then you might be just fine doing it your self...
You'll have a lot of help from a few members here. But the big book is NECESSARY tool for you.
Another problem MIGHT be the squirel cage oil return More Latter IF you have oil into the primary.

I can see your green light is on. That tells me you are on the HDT forum.
Remember that you need to check the oil after it is run and warmed up to give you an accurate measure of engine oil...
Good luck with it.
