I've had no trouble getting to any of my plugs even with the fuel rail on, until #8 drivers side at firewall. I can not get a socket to seat on the plug to remove it I've tried every possible angle and swivel and even tried removing the fuel rail, I can not get the socket to go down all the way to remove it. The boot came out intact and was clean so there's nothing stuck down there, do I need a special socket?? Help please.........

 

got a mirror in there and something flat is across one side of plug hole almost looks like it could be part of intake gasket?? now to SOMEHOW get that out, damn it!

 

Get something thin and sharp, dig it out. If you have air, blow out around the plug.

 

Boy this COP boot design and placement really sucks, how the heck does a little rock get down there? Had to loosen it up with a screw driver then make a contraption to hook up to my VAC to suck it out that added about an hour to my project, I probably wouldn't even had to remove the fuel rail if it weren't for the rock.

 

i had the same thing last year on my old nissan truck with deep plug wells. Mine was jammed in from vibration and I had to pry it out with some long picks.
