does the filter on the wolverine just go in loosly and you tighten up the oil lines, of does it screw in somehow ?

 

I assume you are talking about the oil filter, and yes, it does sit in there, the cover holds it in place, the 3 metric Allen bolts hold the cover on, and there is no need to take the oil lines off, just remove the bolts and swing the cover and lines over a little to get the filter out for cleaning.
