Got a new to me 350z with this piece of trash, pentagon shaped, Nismo oil cap on it. Recessed about a half an inch, can't even get so much as a single finger in there. Need help removing it, and can't believe there's nothing on the internet to help, or even a tool to use. Also, can't believe someone would buy this. Any help appreciated, once this thing is off, it's off for good, piece of junk.

 

Take the engine cover off, toss engine cover in trash

 

I absolutely love this solution Thank you.

 

Simpler solution is to put a rod in one of the corners and hammer it in the counter clockwise direction . It will spin lose right away
