Rear valve cover not coming out
 

Good day! I need some guidance as to why my rear valve cover is not coming out! I removed the bolts that I similarly removed from the front cover but it seems to be stuck to something on the passenger side? Looking in the Haynes manual I do not see any bolts that would be there and I am hesitant to just force it out. Is there bolts holding the cover to something on the passenger side?

I don't know the answer to your question, but you might have a bit more success getting a response if you included a few details, like what kind of car this is and what kind of engine you are dealing with.
