I've been printer for about 6 months and most things I can figure out. Replaced the extruder end this week because I had a severe clog. In replacing the hot end I found that the top end was starting to break in areas. So I print a new top end and there lies the issue. Picture one is how it set on the bed.

The hole from the top to the bottom (vertical) is circular which is good.

Holes on the sides, picture 2, is oval, not good considering that is where the hot end goes.

Also it seems compressed by about 1/4 inch from top to bottem.

So my question is, what the heck is going on?
