I have successfully change 1-7 plugs, but cannot access the 8th plug with a torx screw due to the coolant line being so bulky. I have tried every contraption I know of and asked about 8 different men at Oreily, harbor freight, Home Depot, and Autozone. I’m at a loss. Any mechanics out there who have had success getting to this 8th plug without completely having to take things apart? Any helpful tips or tools you use will be SO appreciated. I’ve nearly stripped the head off the screw trying and trying to unscrew it at gawky angles.

My car is an LR4 2011

oh and one more question. The even numbered plugs seemed to be more compromised than the odd plugs. Why does there seem to be this right sided overcompensation with the cylinders?
